For many Australians, the dream of owning a home has quietly changed. A few years ago, the conversation was largely about “How much can I borrow?” In 2026, a more useful question is: “How much can I comfortably afford to repay every week?” That is a very different way of looking at the property market. A buyer who can technically qualify for an $800,000 mortgage may not necessarily want to commit to repayments that leave little room for groceries, childcare, insurance, rates, utilities, holidays, unexpected repairs and the general cost of living. This is why the $670-a-week repayment mark is an interesting benchmark for Perth buyers. It is not a universal affordability threshold. It doesn’t guarantee a lender will approve a particular loan. And it certainly doesn’t mean a property costing $670 a week to finance is automatically “cheap”. But it is a useful budget filter. And in Perth’s rapidly changing 2026 property market, budget filters matter more than ever.

Perth is no longer the relatively inexpensive capital city it was several years ago. REIWA’s latest data shows that the Perth median house sale price reached $950,000 in July 2026, up 18 per cent year-on-year, while the median unit price reached $681,000, up 22.7 per cent over the year. At the same time, the market is entering a different phase.

• Listings have increased.
• Selling times have lengthened.
• Buyers have more choices.
• Interest rates remain elevated.
• Affordability has become central to almost every serious Perth property conversation.

REIWA reported 6,718 properties listed for sale at the end of July 2026, which was 101.9 per cent higher than a year earlier. Houses were taking a median of 23 days to sell, compared with 13 days a year earlier. That does not mean Perth has suddenly become a buyer’s market, far from it. It means the rules are changing. And for buyers with a firm weekly repayment ceiling, that change could be important. The opportunity is not necessarily to find a detached house in one of Perth’s most fashionable suburbs for $670 a week. The opportunity is to understand which property types, suburbs, deposit structures and price points can realistically bring the mortgage component of home ownership below that figure. 

Walk into almost any Perth home open today, and you’ll see the same tension. Buyers want:

• a good suburb;
• a reasonable commute;
• enough bedrooms;
• access to schools and shops;
• outdoor space;
• a property with future resale appeal;

and, ideally, a mortgage that does not consume their entire household budget. The problem is that these requirements increasingly compete with one another. Perth’s median house price is now around $950,000, according to REIWA’s July 2026 market data, while the metropolitan unit median is $681,000. So when someone says: “I want my repayments below $670 a week,” the answer cannot simply be:

• “Look for a house under $670 a week.”

We need to work backwards.

• What loan size produces a $670 weekly repayment?

And then:

• What purchase price does that loan size support, depending on the buyer’s deposit?

That calculation is the starting point.

What Does a $670 Weekly Mortgage Actually Buy You?

For this blog, we model the repayment benchmark using a 30-year principal-and-interest loan. The Reserve Bank of Australia left the cash rate unchanged at 4.35 per cent in August 2026, following three rate increases earlier in the year. Mortgage rates available to borrowers vary significantly by lender, LVR, borrower profile and loan structure. Canstar’s September 2026 comparison data shows owner-occupier variable rates beginning in the high-5 per cent range, with several competitive products around 5.8–6.0 per cent.

• For our affordability modelling, we use a rate of approximately 5.84 per cent as an illustrative market-rate assumption.
• At that rate, a $500,000 30-year principal-and-interest mortgage would require roughly $680 per week. That means the $670 threshold is surprisingly restrictive.
• A loan of approximately $493,000 produces a repayment close to $670 per week at 5.84 per cent over 30 years.
• At 6 per cent, the equivalent maximum loan falls to roughly $484,000. At 6.5 per cent, it falls further to around $459,000.

A buyer targeting repayments below $670 a week should generally be thinking in terms of a mortgage of approximately $460,000–$493,000, depending on the interest rate. That is the first major affordability insight. Repayment Sensitivity Table:

Loan amount	Approx. weekly repayment at 5.84%	Approx. weekly repayment at 6.5%
$400,000	$544	$583
$420,000	$571	$613
$440,000	$598	$642
$450,000	$612	$656
$460,000	$626	$671
$470,000	$639	$686
$480,000	$653	$700
$490,000	$666	$715
$500,000	$680	$729
$520,000	$707	$758
$540,000	$734	$788
$550,000	$748	$802

This table reveals something important. A $670 weekly target is not really a $670,000 mortgage problem. It’s more like a $460,000–$490,000 mortgage problem. That distinction changes the entire suburb search.

Now we reach the second piece of the puzzle. Suppose a buyer can borrow around $490,000. With a 20 per cent deposit, that could theoretically support a purchase around:

• $612,500

With a 30 per cent deposit:

• about $700,000

With a 10 per cent deposit:

• about $544,000

This is before considering purchasing costs and other transaction expenses. Indicative purchasing power

Deposit	Approx. loan	Approx. property price
10%	$490k	$544k
15%	$490k	$576k
20%	$490k	$613k
25%	$490k	$653k
30%	$490k	$700k
35%	$490k	$754k

This is why saying that a particular suburb is “affordable” without discussing the buyer’s deposit can be misleading. A $700,000 home may be impossible for one buyer and perfectly manageable for another. For example:

Buyer A

• Purchase price: $700,000
• Deposit: $210,000
• Loan: $490,000
• Approx. Repayment: ~$666–$680 per week, depending on the rate

Buyer B

• Purchase price: $700,000
• Deposit: $70,000
• Loan: $630,000
• Repayment: well above $670 a week

Same property. Completely different affordability. This is one of the most important lessons for Perth buyers in 2026.

Before looking at suburbs, it is important to understand where the Perth market currently sits. The Perth market has experienced several years of exceptional growth. But the latest REIWA data indicates a transition. In July 2026:

• Perth’s median house price reached $950,000.
• The median unit price reached $681,000.
• House prices were up 18 per cent year-on-year.
• Unit prices were up 22.7 per cent year-on-year.
• Active listings reached 6,718.
• Listings were more than double the level of a year earlier.
• Median selling time for houses increased to 23 days.
• Median selling time for units reached 19 days.

REIWA’s interpretation is particularly important. The institute described Perth as moving towards more balanced conditions, rather than experiencing a market crash. A more balanced market can mean:

• buyers have more time;
• there is greater choice;
• price negotiations become more realistic;
• vendors have to respond to feedback;
• overpriced properties can sit longer;
• and buyers can become more selective.

For someone with a strict weekly repayment target, this is potentially positive. You do not necessarily need to chase the first property that appears.

• You can compare.
• You can inspect.
• You can negotiate.

And, perhaps most importantly, you can walk away when the numbers do not work.

Don’t search for a suburb first. Search for a repayment range first. If $670 a week is the ceiling, establish your approximate loan capacity.

• Then determine your deposit.
• Then establish the property price range.
• Only after that should you shortlist suburbs.

This prevents one of the most common mistakes buyers make:

• Falling in love with a property before checking whether the numbers work.

In a rising market, emotional buying can be particularly expensive. A buyer sees a beautiful kitchen, renovated bathroom, large backyard and good location. Then the mortgage broker says:

• “The repayments will be around $850 a week.”

Suddenly the dream home becomes a financial burden. The better strategy is the reverse:

• Budget → Loan → Property price → Suburb → Property

not:

• Suburb → House → Emotion → Mortgage

Which Perth Suburbs Can Actually Work?

At current 2026 Perth prices, finding a median detached house that comfortably fits under the $670 weekly repayment benchmark with a standard 20 per cent deposit is becoming difficult. Several suburbs once considered affordable are now above $700,000. But that does not mean the search is over. It means buyers need to look at:

• lower-quartile properties;
• two-bedroom homes;
• units;
• villas;
• townhouses;
• older established properties;
• smaller landholdings;
• suburbs where the median remains comparatively low;
• properties requiring cosmetic rather than structural renovation;
• and properties where a larger deposit can reduce the mortgage.

The strongest candidates include parts of: Armadale; Camillo; Medina; Orelia; Parmelia; Midland; Kelmscott; Gosnells; Maddington; Brookdale; Cooloongup and selected unit markets across established suburbs. But each needs to be understood properly.

1. Armadale: Still One of Perth’s Key Affordability Markets

If affordability is the primary objective, Armadale deserves serious attention. REIWA’s latest suburb data places Armadale’s median house price at approximately $700,000 for the 12 months to August 2026.

• Its median unit price is approximately $595,000.
• The lower quartile for houses is around $650,000.

This matters because the median isn’t necessarily the price of every property. A buyer looking below the median may find properties closer to the $600,000–$650,000 range. Armadale snapshot:

Metric	2026
Median house	~$700,000
Lower house quartile	~$650,000
Median unit	~$595,000
Median house rent	~$630/week
Median unit rent	~$570/week
Median house time on market	~21 days

A $650,000 property with a 25 per cent deposit would require a loan of approximately $487,500. At around 5.84 per cent, that sits close to the $670 weekly repayment threshold. This creates a very practical affordability scenario:

• $650,000 purchase
• 25% deposit = $162,500
• Loan = $487,500
• Approximate repayment = around $660–$670/week

That is not a recommendation to buy any particular property. It simply demonstrates how a higher deposit can make a property price work.

The suburb has an established urban structure, transport infrastructure, schools, shops and access to the wider south-eastern metropolitan corridor. It is also important to understand that “affordable” does not mean “risk-free”. The buyer needs to assess:

• individual street quality;
• property condition;
• zoning;
• land size;
• proximity to transport;
• surrounding development;
• rental demand;
• insurance;
• flood or drainage considerations where applicable;
• future infrastructure;
• and resale depth.

This is where suburb-level research becomes more valuable than looking at the median alone.

2. Camillo: A Strong Contender for the $670 Benchmark

Camillo is one of the more interesting suburbs for affordability-focused buyers. REIWA’s latest data places the median house price at around $750,000, with the lower quartile around $690,000.

• At first glance, that seems too expensive for our target. But the property mix tells a different story.
• Two-bedroom houses have a median of around $625,000, while three-bedroom houses sit around $735,000.

This illustrates why property type matters. A buyer searching specifically for a smaller two-bedroom property may be able to access a much lower entry point than the headline suburb median. Camillo snapshot:

Property type	Approx. 2026 median
Overall houses	$750k
2-bedroom house	$625k
3-bedroom house	$735k
4-bedroom house	$795k
Units	~$616k
Median house rent	~$630/week

A $625,000 purchase with a 22 per cent deposit would require approximately a $487,500 mortgage. Again, that puts the mortgage component close to the $670 weekly threshold. This is exactly the kind of suburb where a buyer should not be discouraged by the headline median. Instead, filter by:

• 2 bedrooms
• established property
• $600,000–$650,000
• low-maintenance
• good street
• transport access

That produces a much more useful search.

3. Medina: One of the Clearest Affordability Plays

Medina is particularly interesting because its median house price remains below $700,000. REIWA’s September 2026 data places the median house price at approximately $690,000, with a lower quartile of around $646,000. The median house rent is approximately $587 per week. Medina snapshot:

Metric	2026
Median house	$690k
Lower quartile	$646k
2-bedroom house	~$670k
3-bedroom house	~$702k
Median house rent	$587/week
Median unit	~$515k

The unit market is even more interesting. At approximately $515,000, a buyer with a 10 per cent deposit would borrow around $463,500. That would be close to the $670 weekly repayment threshold, assuming roughly 5.84 per cent. With a larger deposit, the repayment becomes considerably more manageable. Medina therefore deserves attention from:

• first-home buyers;
• downsizers;
• investors;
• buyers prioritising land over prestige;

and households prepared to trade CBD proximity for affordability.

4. Orelia: Affordability With a Kwinana Location

Orelia is another suburb worth putting on the 2026 affordability radar.

• REIWA reports a median house price of approximately $720,000, with a lower quartile around $670,000.
• But the two-bedroom house median is approximately $683,000, while the unit median is only around $477,500.

That unit figure dramatically changes the repayment equation. Orelia snapshot:

Metric	Approx. 2026 figure
Median house	$720k
Lower quartile	$670k
3-bedroom house	$683k
4-bedroom house	$820k
Median unit	$477.5k
Median house rent	$600/week
Median unit rent	$490/week

A $477,500 purchase financed at 80 per cent LVR would mean a loan of only around $382,000. At approximately 5.84 per cent over 30 years, that is comfortably below $670 per week. This is one of the clearest examples of the difference between:

• “affordable suburb”

and

• “affordable property”.

Orelia may not have a median house price low enough for every buyer. But it offers property types that can fit the weekly repayment objective much more comfortably.

5. Parmelia: A Suburb Worth Looking at Beyond the Headline Median

Parmelia has also experienced significant price growth.

• REIWA’s latest figures put the median house price at approximately $740,000, up strongly over the year.
• But the lower quartile is around $680,000, while the median for a two-bedroom house is approximately $589,000.

That is a very important distinction. Parmelia 2026 snapshot:

Metric	Approx. figure
Median house	$740k
Lower quartile	$680k
2-bedroom house	$589k
3-bedroom house	$720k
4-bedroom house	$790k
Median unit	$474k
Median house rent	$600/week

A two-bedroom house at roughly $589,000 could be financed within the $670 weekly target even with a relatively modest deposit, subject, of course, to the borrower’s actual rate and loan terms. The unit market creates an even larger buffer. This makes Parmelia particularly interesting for buyers willing to compromise on:

• house size;
• age;
• land size;
• or number of bedrooms.

6. Midland: The Affordability Story Is Changing

Midland is fascinating because it combines relatively accessible property prices with established infrastructure.

• REIWA’s September 2026 data puts the median house price at approximately $710,000, with the lower quartile around $645,000.
• The unit median is approximately $566,000.

Midland market snapshot:

Metric	Approx. 2026 figure
Median house	$710k
Lower quartile	$645k
Median unit	$566k
2-bedroom house	$715k
3-bedroom house	$690k
Median house rent	$695/week
Median unit rent	$630/week
House time on market	13 days

Midland’s 13-day median selling time is particularly notable. Even in a more balanced Perth market, affordable and well-located property can remain highly competitive. This is an important point for buyers:

• Affordable does not automatically mean easy to buy.

In fact, affordability can create competition. If a suburb has a lower price point but good transport, employment access, shopping and infrastructure, buyers may compete strongly for the best properties. Midland has a different proposition from outer southern suburbs. It sits within an established urban corridor with:

• train infrastructure;
• major retail;
• healthcare;
• employment;
• access towards the Perth Hills;
• and connection to the broader eastern metropolitan area.

That means a buyer is not simply purchasing a cheaper house. They are buying into a location with established urban infrastructure. For long-term ownership, this distinction matters.

7. Kelmscott: More Expensive Than It Looks, But Still Worth Screening

Kelmscott’s median house price is now approximately $765,000, according to REIWA’s latest data. At first glance, that appears outside the $670 weekly mortgage objective.

• The lower quartile is around $683,000.
• Two-bedroom houses are around $680,000, while three-bedroom houses are around $740,000.
• The unit median is around $542,500.

That unit market is where the affordability opportunity becomes obvious. Kelmscott snapshot:

Metric	Approx. 2026 figure
Median house	$765k
Lower quartile	$683k
2-bedroom house	$680k
3-bedroom house	$740k
Median unit	$542.5k
Median house rent	$650/week
Median unit rent	$650/week

A $542,500 unit with a 20 per cent deposit requires a mortgage of around $434,000. At around 5.84 per cent over 30 years, that would be comfortably under the $670 weekly benchmark. This is a strong example of a buyer using property type to preserve affordability.

8. Gosnells: A Suburb Where Smaller Properties Matter

Gosnells has moved considerably over the past year. REIWA’s latest data puts the median house price at approximately $765,000, with a lower quartile around $700,000.

• The unit median, however, is approximately $591,500.
• Two-bedroom houses are around $681,000.
• Three-bedroom houses are around $738,000.

Gosnells snapshot:

Metric	2026
Median house	$765k
Lower quartile	$700k
2-bedroom house	~$681k
3-bedroom house	~$738k
Median unit	~$591.5k
Median house rent	$655/week
Median unit rent	$640/week

This means Gosnells is unlikely to be a straightforward 20 per cent deposit + median house + $670 repayment suburb. But it remains relevant if buyers consider:

• units;
• smaller homes;
• properties below the suburb median;
• or a higher deposit.

That distinction is essential. 

9. Maddington: Strong Growth, But Still Some Entry-Level Options

Maddington’s median house price has risen to approximately $770,000, according to REIWA’s latest data. That is a major change from the affordability perception the suburb historically carried. But there are still lower-priced segments. REIWA reports:

• 2-bedroom houses around $590,000;
• 3-bedroom houses around $750,000;
• 4-bedroom houses around $850,000;
• units around $592,500.

The two-bedroom market is therefore the obvious place to investigate for a $670 weekly target. Maddington snapshot:

Property	Approx. median
Overall houses	$770k
2-bedroom house	$590k
3-bedroom house	$750k
4-bedroom house	$850k
Units	$592.5k
House rent	$700/week

This is another reminder that suburb medians can hide meaningful affordability pockets.

10. Brookdale: An Outer-South Opportunity

Brookdale is another suburb that deserves attention from buyers who are willing to trade centrality for affordability. REIWA’s latest data shows:

• median house price: approximately $750,000;
• lower quartile: approximately $700,000;
• three-bedroom median: around $700,000;
• four-bedroom median: around $768,000;
• median rent: approximately $690 per week.

The suburb has experienced strong annual growth. That is both an opportunity and a warning. A buyer should not assume that because a suburb was affordable five years ago, it remains cheap today. The Perth market has repriced many of these locations. The better question is:

• “Which individual properties remain attractively priced relative to their current local market?”

That is a much more sophisticated way to buy.

11. Cooloongup: An Interesting Rockingham-Area Option

Cooloongup’s median house price is approximately $770,000, according to REIWA. However, the median unit price is about $593,000.

• Three-bedroom houses sit around $730,000, while four-bedroom houses are around $817,000.
• The suburb’s median house rent is approximately $600 per week.

Cooloongup snapshot:

Metric	2026
Median house	$770k
Lower quartile	$706k
3-bedroom house	$730k
4-bedroom house	$817k
Median unit	$593k
Median house rent	$600/week
House selling time	15 days

For a buyer who wants access to the Rockingham corridor but needs to keep mortgage repayments contained, units may therefore be a more realistic path than detached houses.

The Real Shortlist: Where Does $670 a Week Actually Work?

If we focus purely on the math rather than the suburb name, the strongest opportunities fall into three groups.

Group A: Detached homes that can work with a larger deposit

These include selected properties in:

• Armadale;
• Camillo;
• Medina;
• Parmelia;
• Orelia;
• Midland;
• Maddington;
• Kelmscott;
• Brookdale.

The key is purchasing below or around the lower quartile, rather than automatically buying at the median.

Group B: Units and villas that work with a more conventional deposit

This is where the affordability equation becomes significantly easier. Potential areas include:

• Orelia;
• Parmelia;
• Armadale;
• Kelmscott;
• Midland;
• Gosnells;
• Maddington;
• Cooloongup;
• and selected other established Perth suburbs.

A unit in the $475,000–$550,000 range can produce repayments significantly below $670 a week with a 20 per cent deposit.

Group C: Established suburbs where smaller homes create an entry point

This is the most overlooked strategy. A suburb may have an $800,000 median house price but still contain:

• two-bedroom villas;
• older cottages;
• small-lot homes;
• strata properties;
• duplexes;
• downsizer homes;
• or properties requiring cosmetic renovation.

The buyer does not necessarily need to leave the suburb. They may need to change the property brief.

Why the Unit Market Deserves Much More Attention in 2026

One of the strongest conclusions from the numbers is this: If your repayment ceiling is $670 a week, don’t automatically restrict your search to houses. Perth’s unit market has become increasingly relevant.

• REIWA’s July 2026 data put the Perth median unit price at $681,000, compared with $950,000 for houses. The gap between houses and units is now one of the most important affordability mechanisms in the metropolitan market.
• REIWA reported that the median Perth unit rent rose to about $700 per week at the end of the 2025–26 financial year, up 7.7 per cent. This reflects continuing rental demand.

But buyers need to be careful here. High rental demand does not automatically make every unit a good investment. A unit must still be assessed for:

• strata levies;
• sinking fund;
• special levies;
• building condition;
• insurance;
• parking;
• owner-occupier appeal;
• rental demand;
• location;
• and future resale liquidity.

A $500,000 unit may have a lower mortgage repayment than a $650,000 house. But the mortgage is only one part of ownership. This is where affordability analysis often goes wrong. A buyer calculates: Mortgage = $620/week. Then assumes the property costs $620 a week. There may also be:

• council rates;
• water charges;
• strata levies;
• building insurance;
• contents insurance;
• maintenance;
• utilities;
• pest control;
• land tax in investment scenarios;
• and potential special levies.

For a house, maintenance can be unpredictable. For a unit, strata expenses can be predictable but potentially substantial. So treat $670 as a mortgage-repayment benchmark, not a complete housing-cost benchmark. Make that distinction very clear to every buyer.

Interest rates remain one of the biggest variables in the affordability equation. The RBA cash rate is currently 4.35 per cent, following three increases earlier in 2026. The RBA has also indicated that inflation remains too high and that further increases remain possible if upside risks materialise. This means buyers should avoid building their entire budget around today’s lowest advertised mortgage rate. The right question is:

• “Could I still comfortably afford this loan if my rate increased?”

That is particularly important for buyers targeting a $670 ceiling. A buyer whose repayment is already exactly $670 at 5.84 per cent has almost no buffer. A better approach may be to target:

• $550–$620 per week

rather than:

• $670 exactly.

That gives the household more room if rates move. Let’s consider a buyer borrowing $450,000. At approximately 5.84 per cent:

• ~$612/week

At 6.5 per cent:

• ~$656/week

That is a much healthier position than borrowing $490,000. At $490,000:

• ~$666/week at 5.84%

but approximately:

• ~$715/week at 6.5%.

The difference is significant.

• The buyer who deliberately chooses a $450,000 mortgage has built a buffer.
• The buyer who maximises their borrowing to $490,000 has effectively used the entire repayment budget.

This is why responsible affordability research should never ask only:

• “Can I get the loan?”

It should also ask:

• “Can I live comfortably with the loan?”

The Investment Angle: Don’t Confuse Yield With Affordability

Consider Cannington. REIWA identified Cannington among the top-performing Perth suburbs for house rental yield during 2025–26, with a reported yield around 5.0 per cent, based on a median house price of $780,000 and median rent of $750 a week. That is attractive from an investment perspective. But that doesn’t mean a $780,000 house is affordable for someone targeting a $670 weekly mortgage. Investment affordability and owner-occupier affordability are not the same thing. An investor may be assessing:

• rental income;
• tax;
• depreciation;
• vacancy;
• capital growth;
• yield;
• financing.

An owner-occupier may care more about:

• weekly cash flow;
• lifestyle;
• school zones;
• commute;
• maintenance;
• future flexibility.

The best suburb for one buyer may be completely wrong for another.

First-home buyers should also consider government schemes when assessing affordability. The Australian Government’s 5% Deposit Scheme allows eligible buyers to purchase with a deposit as low as five per cent, subject to eligibility and price caps. For Western Australia’s capital-city market, the published property price cap is $850,000. That makes several Perth suburbs relevant to eligible first-home buyers. However, a critical point: A smaller deposit reduces the cash needed upfront, but it does not make the mortgage cheaper. For example, A $600,000 property with a 5 per cent deposit:

• Deposit = $30,000
• Loan = $570,000

That mortgage is well above the loan size associated with a $670 weekly repayment. The scheme can solve a deposit problem. It does not automatically solve a repayment problem. This is one of the most important distinctions first-home buyers need to understand. Let’s use a $600,000 property.

Scenario A — 5% deposit

• Deposit: $30,000
• Mortgage: $570,000
• Approximate repayment at 5.84%: well above $670/week.

Scenario B — 20% deposit

• Deposit: $120,000
• Mortgage: $480,000
• Approximate repayment: around $653/week.

Same property. Very different weekly budget. This is why saving a larger deposit can be financially powerful even if it means waiting longer. However, waiting also has a cost if property prices rise. There is no universal answer. The right decision depends on:

• household income;
• savings rate;
• property market;
• interest rate;
• expected price growth;
• rent being paid while saving;
• and personal circumstances.

A market like Perth in 2026 is becoming increasingly difficult to understand through headline numbers alone. This is where local agency knowledge becomes valuable. Bargoti Real Estate builds its reputation on local market knowledge, personalised service, and a human approach to buying, selling, investing, and renting. That philosophy matters particularly when affordability is the objective. Because the difference between a good and bad purchase is not always visible in the suburb median, two homes in the same suburb can have completely different:

• street appeal;
• land characteristics;
• renovation requirements;
• rental appeal;
• resale potential;
• parking;
• orientation;
• building condition;
• strata costs;
• and buyer demand.

For example, consider a suburb with a $700,000 median. One property may sell for $640,000 because it needs substantial work. Another may sell for $720,000 because it is renovated, well positioned and highly desirable. The cheaper property is not automatically the better buy.

Why $670 Is a Useful Benchmark — But Not a Magic Number

It is tempting to call $670 the “affordable mortgage”. For one household:

• $670/week may be very comfortable.

For another:

• $670/week may be financially stressful.

A household earning $180,000 a year has a very different capacity from a household earning $90,000. Likewise:

• one income;
• two incomes;
• childcare;
• car loans;
• HECS-HELP debt;
• credit cards;
• dependants;
• insurance;
• and other commitments

All influence borrowing capacity. Banks do not approve loans based solely on the repayment figure. They assess the applicant’s overall financial position and apply serviceability requirements. So view this article as a property market affordability framework, not financial advice or a borrowing approval.

• The advertised property price is not the most useful number.
• The suburb median is not the most useful number.
• Even the interest rate is not the most useful number.

For a buyer with a fixed weekly budget, the most useful number is: Total sustainable weekly housing cost. That starts with:

• Mortgage repayment

and then adds:

• Rates + insurance + utilities + maintenance + strata where applicable.

Once you factor those costs in, the property that looked affordable at $670 a week may no longer be comfortable. That is why a buyer targeting a $670 mortgage should ideally search for properties that produce a mortgage closer to $550–$620. The remaining buffer can absorb ownership costs and interest-rate movement.

Consider three hypothetical buyers.

Buyer 1: Maximum borrower

• Loan: $490,000
• Mortgage: ~$666/week
• There is almost no mortgage buffer.

Buyer 2: Balanced borrower

• Loan: $450,000
• Mortgage: ~$612/week
• Mortgage headroom is about $58/week.

Buyer 3: Conservative borrower

• Loan: $420,000
• Mortgage: ~$571/week
• Mortgage headroom is around $99 a week.

That difference compounds over time. A conservative buyer may have more capacity to:

• make extra repayments;
• build an emergency fund;
• renovate;
• replace a car;
• handle rate rises;
• or take time off work.

This is why the “cheapest house I can technically buy” is rarely the same thing as the “best house I can comfortably own”.

What Should Buyers Give Up First?

If $670 is the hard mortgage ceiling, something usually has to move. The key is deciding what to compromise on.

Compromise 1: Property size

Instead of four bedrooms:

• Look at three.
• Instead of three:
• Look at two.

This can meaningfully reduce the purchase price.

Compromise 2: Land size

A 250 sqm property can still provide a perfectly functional home. Not every buyer needs 600–800 sqm. Smaller land can also mean:

• less mowing;
• less maintenance;
• lower landscaping costs;
• and potentially easier upkeep.

Compromise 3: Distance from the CBD

This is often the biggest lever.

• Moving further out can open up dramatically different price points. But the buyer needs to calculate the true cost.
• If moving 20 kilometres further out adds $150 a week in fuel, parking and commuting time, some of the mortgage savings disappears.

Affordability is not simply a property calculation. It is a lifestyle calculation.

The Commuting Cost Test

Imagine two homes.

Home A

• Mortgage: $650/week
• Travel cost: $80/week
• Total: $730/week

Home B

• Mortgage: $580/week
• Travel cost: $30/week
• Total: $610/week

Home B is clearly more affordable. But imagine Home C:

• Mortgage: $540/week
• Travel: $150/week
• Total: $690/week

The cheapest mortgage does not necessarily create the cheapest lifestyle. This is why Perth buyers should consider employment location when comparing outer-suburban opportunities.

Compromise #4: Renovation

A property needing cosmetic work may be cheaper. But buyers must distinguish between:

• cosmetic renovation

and

• structural risk.

Cosmetic:

• paint;
• flooring;
• landscaping;
• light fittings;
• kitchen cabinetry;
• bathroom finishes.

Potentially manageable. Structural:

• roof issues;
• serious water damage;
• foundation problems;
• major electrical defects;
• extensive termite damage;
• significant plumbing problems.

Potentially expensive. The cheapest property can become the most expensive property if the buyer underestimates repairs.

Compromise #5: Prestige

This is the hardest psychological compromise.

• Many buyers want the suburb they grew up admiring. But property ownership does not need to begin with the final dream home.
• A $500,000–$600,000 property that builds equity may become a stepping stone. The first property does not need to be the property you own forever.

It needs to be a property you can afford, enjoy and hold comfortably.

A good affordability article should not only tell buyers where to look. It should also tell them where the numbers may not work. For example, Perth’s median house price is now around $950,000. That means a buyer with a $670 weekly mortgage budget and a conventional 20 per cent deposit is unlikely to purchase a median-priced Perth house comfortably. The numbers do not support it. At a 20 per cent deposit on $950,000:

• Deposit: $190,000
• Loan: $760,000

That mortgage is far above the repayment threshold. The same applies to many established premium suburbs. A buyer cannot solve an affordability problem by wishing the median price were lower. They need to change:

• suburb;
• property type;
• deposit;
• property size;
• or budget.

A Smarter Search Strategy for a $670 Budget

If I were constructing a Perth property search around this repayment target, I would approach it in seven steps.

Step 1: Set the repayment ceiling

• Maximum mortgage: $670/week
• But ideally target: $550–$620/week

Step 2: Establish the actual interest-rate assumption

• Do not use the cheapest rate advertised online.
• Use a realistic rate based on the borrower’s likely circumstances.
• Then run a stress test at a higher rate.

Step 3: Establish the loan amount

• At approximately 5.84 per cent, Target loan: $400k–$490k

Step 4: Add the deposit

Now determine the purchase price. A $450,000 loan with a:

• 20% deposit → ~$562,500 property
• 25% deposit → ~$600,000 property
• 30% deposit → ~$643,000 property
• 35% deposit → ~$692,000 property

Step 5: Search suburbs

Now shortlist locations. The search could include: Armadale, Medina, Orelia, Parmelia, Camillo, Midland, Kelmscott, Gosnells, Maddington, Cooloongup, plus suitable unit/villa markets.

Step 6: Filter by property type

Look for:

• 2-bedroom houses;
• smaller 3-bedroom homes;
• villas;
• townhouses;
• units;
• duplexes;
• smaller lots.

Step 7: Assess the individual property

• Finally ask: Is this actually a good property?

That is where the suburb research ends, and property due diligence begins.

A 2026 Perth Buyer Scorecard

Factor	Weight
Purchase price	20%
Mortgage repayment	20%
Location	15%
Transport	10%
Property condition	10%
Resale demand	10%
Rental demand	5%
Land/property size	5%
Ongoing costs	5%

This stops buyers from deciding purely on price.

• A $520,000 property might score badly if it requires $100,000 of work.
• A $600,000 property may score better if it is structurally sound, well located and easy to resell.

The latest numbers offer several major lessons.

• Perth is still expensive: A $950,000 median house price is no longer an affordable market in the traditional sense.
• Units provide a much more realistic entry point: The $681,000 Perth unit median remains substantially below the house median.
• Supply has improved: Listings were significantly higher in mid-2026 than the previous year.
• Buyers have regained negotiating power: REIWA says buyers now have more choice and more time than during the extreme shortage period.
• The market is not uniform: Suburb-level performance varies dramatically.
• Affordable properties can still be competitive: Midland, Armadale and other lower-price markets can still sell quickly.
• Interest rates remain an affordability constraint: The RBA’s 4.35 per cent cash rate and the possibility of further movement mean borrowers need buffers.

Australian property commentary often treats the country as one market. That is a mistake. WA has different:

• population dynamics;
• economic drivers;
• housing supply;
• geography;
• construction pipeline;
• employment structure;
• migration patterns;
• and buyer behaviour.

REIWA has stressed that WA should not be interpreted simply through the lens of eastern-state markets. For Perth buyers, that means national headlines such as: “Australian property prices are falling” are not sufficient. The more useful question is: “What is happening in my Perth suburb?”

The Market Is Becoming More Negotiable — Not Necessarily Cheap

This may be the most accurate description of Perth in late 2026. The market has not suddenly returned to 2021 prices. It has simply become less frantic.

• More active listings give buyers more choice.
• The longer selling times give buyers more breathing room.
• Higher interest rates also make buyers more price-sensitive.

REIWA reported that houses were taking 23 days to sell in July, compared with 13 days a year earlier. For a buyer, that is significant. It means there may be more opportunity to negotiate. But negotiation does not mean vendors will accept unrealistic offers. The best strategy is:

• Know the comparable sales.
• Know the property’s condition.
• Know the suburb.
• Know your finance limit.
• Then negotiate from evidence.

Suppose you find a property advertised at $650,000. You have calculated that you need the purchase price to remain below $625,000 to keep your loan within your preferred repayment range. Do not simply say:

• “I’ll offer $600,000 because I want a cheap house.”

Instead:

• research recent comparable sales;
• assess days on market;
• inspect the condition;
• compare land size;
• assess renovation;
• understand vendor motivation where possible;
• and make an evidence-backed offer.

The strongest buyer is not the buyer with the biggest budget. It is the buyer who understands the property’s value better than competing buyers.

There is also a seller-side lesson. A growing number of buyers are likely to be financially constrained. That means a property priced at $620,000 may access a completely different pool of buyers from a property priced at $680,000. The $60,000 difference can materially affect:

• deposit requirements;
• borrowing capacity;
• mortgage serviceability;
• first-home-buyer eligibility;
• and repayment comfort.

Price brackets matter. Crossing a psychological or financial threshold can remove a large portion of potential buyers. This is one reason accurate pricing becomes increasingly important as the market balances out.

The Real Opportunity: Finding the Affordable Edge of Established Suburbs

One of the most interesting strategies for 2026 is not necessarily chasing the cheapest suburb. It is finding the affordable edge of a better-established suburb. For example, a buyer may not afford the typical family house in an established suburb. But they may afford:

• an older villa;
• a two-bedroom unit;
• a small-lot home;
• a duplex;
• or a property needing cosmetic updating.

This can be powerful because buyers gain access to the suburb’s broader infrastructure. They may benefit from:

• established schools;
• public transport;
• shopping;
• parks;
• employment;
• mature streets;
• and better resale liquidity.

That is often a better long-term strategy than simply chasing the lowest dollar-per-square-metre figure.

First-home buyers often dominate the affordability conversation. But downsizers can play an equally important role. An older owner may sell a $900,000 family home and purchase a $600,000 villa. That creates a much smaller mortgage — or potentially no mortgage at all. For younger buyers, this also matters because downsizer activity can increase the supply of family homes. Perth’s demographic transition means the demand for low-maintenance homes is likely to remain relevant. This makes villas, townhouses, units, and small-lot homes important parts of the market. New builds can appear attractive because of:

• government incentives;
• modern construction;
• energy efficiency;
• warranties;
• lower immediate maintenance.

But buyers need to compare the total cost. A $550,000 house-and-land package can potentially become:

• $550,000 land/build cost;
• plus upgrades;
• plus landscaping;
• plus fencing;
• plus blinds;
• plus driveway;
• plus site costs;
• plus other inclusions.

The advertised starting price may not represent the finished product. Established properties can therefore offer greater certainty.

Established Property vs New Build

Factor	Established property	New build
Price certainty	Often stronger	Can vary
Land	Existing	Depends on package
Immediate occupancy	Usually possible	Construction period
Maintenance	Depends on age	Usually lower initially
Renovation	Possible	Often unnecessary
Hidden upgrade costs	Usually inspectable	Can emerge during build
Established suburb	Often	Depends on location
Rental history	May exist	No history initially

A suburb list is useful. But it is only the first filter.

Consider Camillo.

• The overall median house price is approximately $750,000.
• Yet the two-bedroom median is around $625,000.

Consider Maddington.

• The overall median is approximately $770,000.
• Yet two-bedroom houses are around $590,000.

Consider Parmelia.

• The median is around $740,000.
• Yet two-bedroom houses are around $589,000.

These differences are enormous. They show that bedrooms can matter more than suburb medians.

For buyers with a strict repayment ceiling, two-bedroom homes deserve serious consideration. A two-bedroom property can:

• lower purchase price;
• reduce maintenance;
• suit singles/couples;
• suit downsizers;
• suit some investors;
• and provide a lower mortgage.
• It may not be the traditional family home.

But affordability means buying the right property for your current stage of life. A buyer can always reassess later.

What About Renting Instead?

This is another important question. Perth’s median house rent is around $750 per week and the median unit rent around $700, according to REIWA’s end-of-financial-year 2025–26 figures. That makes the decision more complicated. A household paying $700–$750 rent may ask:

• “Would I rather put that money towards a mortgage?”

But ownership also involves:

• deposit;
• stamp duty where applicable;
• rates;
• maintenance;
• insurance;
• interest;
• transaction costs.

Renting provides flexibility. Buying provides ownership and potential equity growth. Neither is automatically superior. A smaller mortgage provides something property investors rarely talk about: sleeping room. A $420,000 mortgage can be much easier to manage than a $600,000 mortgage. It can allow:

• faster principal reduction;
• larger savings;
• emergency funds;
• future renovations;
• investment contributions;
• and flexibility during economic downturns.

The objective should not simply be: “Get into the market.” It should be: “Get into the market without becoming financially trapped.”

A Buyer Should Ask These 15 Questions Before Making an Offer

• 1. What is the actual repayment at my lender’s rate?
• 2. What happens if rates rise?
• 3. What is my total cash requirement?
• 4. What are the council rates?
• 5. What are the water charges?
• 6. If it is strata, what are the levies?
• 7. Is there a sinking fund?
• 8. Are there proposed special levies?
• 9. What are comparable properties selling for?
• 10. How long has this property been listed?
• 11. Why is the vendor selling?
• 12. What work will the property need?
• 13. How easy will it be to resell?
• 14. What is the local rental demand?
• 15. Would I still want this property if prices stayed flat for three years?

Imagine you buy a $600,000 property. For the next three years, the property price does not increase. Would you still be happy living there?

• If yes: That is a strong sign.
• If the only reason the property makes sense is: “It will definitely be worth $750,000 in three years.”

Then the buyer is speculating. No property market guarantees capital growth.

The Most Promising Affordability Strategy for Perth in 2026

After examining the current data, the strongest conclusion is not that one suburb is “the cheapest”. It is this: Perth buyers targeting repayments below $670 should focus on the intersection of three things:

1. Lower purchase price

• Ideally around $550,000–$650,000 depending on deposit.

2. Smaller or alternative property type

• Units, villas, townhouses and smaller homes.

3. Established infrastructure

• Transport, employment, shopping, schools and services.

This combination produces a more sustainable search strategy than simply looking for the cheapest suburb. If affordability is the dominant objective, I would divide the Perth opportunities into tiers.

Tier 1 — Strongest affordability potential

Medina

• median house price around $690k;
• lower quartile around $646k;
• unit market around $515k;
• comparatively accessible entry prices.

Parmelia

• two-bedroom houses around $589k;
• units around $474k;
• established Kwinana location.

Orelia

• units around $477.5k;
• lower quartile houses around $670k.

Armadale

• median house around $700k;
• lower quartile around $650k;
• units around $595k.

Tier 2 — Strong if You Buy the Right Property

Camillo

• Two-bedroom houses around $625k make the suburb interesting despite the $750k overall median.

Midland

• Lower-quartile houses are around $645k, and units are around $566k.

Kelmscott

• Units around $542.5k and two-bedroom houses around $680k.

Gosnells

• Two-bedroom houses around $681k and units around $591.5k.

Tier 3 — Works Mainly With the Right Deposit

Maddington

• Two-bedroom houses around $590k make it interesting, despite the $770k overall median.

Brookdale

• The three-bedroom market around $700k means you may need a larger deposit.

Cooloongup

• Units around $593k provide a more comfortable entry point than detached houses.

Let’s simplify everything. If your maximum mortgage repayment is:

• $670 per week

you should probably avoid thinking: “I need a $670,000 property.”

Instead think:

• “I need approximately a $460,000–$490,000 mortgage, depending on the rate.”

Then work backwards. If you have:

• $100,000 deposit

your property range may be around:

• $560,000–$590,000

If you have:

• $150,000 deposit

you may be looking around:

• $610,000–$640,000

If you have:

• $200,000 deposit

you may be looking around:

• $650,000–$690,000

The larger the deposit, the more suburbs you can choose from. A buyer may qualify for $700,000. That does not mean they should spend $700,000. If their preferred repayment is $670, they may be better off borrowing $430,000–$460,000.

• The economy remains uncertain.
• Interest rates remain elevated.
• Inflation remains a concern.
• Household expenses remain high.
• And Perth property prices have already risen dramatically.

A buyer entering the market today should therefore prioritise sustainability.

Forecasting property prices with precision is impossible. However, the current market data gives us some useful signals. REIWA says Perth price growth has peaked but does not characterise the market as a crash. At the same time:

• listings have risen;
• selling times have increased;
• sales activity has softened;
• buyers have more choice;
• and interest rates remain restrictive.

This suggests the next stage may be less about runaway price growth and more about quality, negotiation, and affordability. That’s a healthier environment for disciplined buyers. A market that rises 20 per cent a year creates urgency. A more balanced market creates choice. For a buyer with a $670 repayment ceiling, choice is valuable. You can reject:

• overpriced properties;
• poor streets;
• excessive renovation;
• bad layouts;
• high strata costs;
• and properties that do not fit your finances.

The buyer who knows their numbers can become more powerful as the market becomes more balanced.

The Bottom Line

REIWA’s latest data shows a median house price of around $950,000 and a median unit price of around $681,000. But affordability has not disappeared. It has moved towards:

• smaller properties;
• lower-quartile transactions;
• units;
• villas;
• established outer suburbs;
• smaller lots;
• larger deposits;
• and more disciplined negotiation.

For a buyer determined to keep mortgage repayments below $670 a week, the numbers suggest a mortgage of roughly $460,000–$490,000 under current illustrative interest-rate assumptions. That means the realistic property price depends heavily on the deposit.

• With around 20 per cent down, buyers are generally looking around the $575,000–$615,000 region.
• With a 25–30 per cent deposit, the potential purchase range expands towards $615,000–$700,000.

That puts parts of the Perth market back on the table. Suburbs such as Armadale, Medina, Orelia, Parmelia, Camillo, Midland, Kelmscott, Gosnells, Maddington, Brookdale and Cooloongup all deserve investigation — but not necessarily for their headline median house price. The opportunity often sits underneath the headline. It may be the:

• two-bedroom house instead of the four-bedroom house;
• unit instead of the detached home;
• lower-quartile property instead of the suburb median;
• established home instead of the brand-new build;
• $620,000 purchase with a larger deposit instead of a $700,000 purchase with maximum borrowing.

That is the real affordability story in Perth in 2026.

The Perth market is entering a new phase. The days of buying anything in a desirable suburb and assuming rapid growth will solve every affordability problem are gone. Today’s buyer needs to be more deliberate.

• Start with the weekly repayment.
• Work backwards to the mortgage.
• Work backwards again to the purchase price.
• Then identify suburbs.
• Then identify property types.
• Then inspect individual homes.
• And finally, negotiate based on evidence.

That is how a buyer turns a $670 weekly ceiling from a limitation into a strategy. For many Perth buyers, the answer will not be a spectacular four-bedroom home on a large block.

• It might be a well-positioned two-bedroom house in Medina.
• It might be a unit in Orelia.
• It might be a smaller home in Armadale.
• It might be a two-bedroom property in Camillo.
• It might be a villa in Parmelia.
• It might be a unit in Kelmscott or Midland.

Or it might be an overlooked property in an established suburb where the headline median looks too expensive, but an individual property sits comfortably within the buyer’s actual budget. And that is the important distinction. For buyers working with a firm weekly repayment limit, that disciplined approach could be the difference between simply entering the property market and entering it with confidence.
