Falling house prices do not automatically mean more affordable homes. Buyers need the right property to become cheaper, a manageable repayment and enough borrowing capacity—all at the same time. October's Melbourne reporting shows why those conditions can pull in opposite directions.
The latest twist is not another national crash forecast. It is a split inside the market: the homes buyers can realistically compete for may be holding up—or rising—even while the city-wide headlines turn red.
For investors, that matters too. A weaker city index does not guarantee a discounted entry-level purchase, and an apparently cheaper property can still require more cash each month.
The city fell. Parts of its cheapest quarter went the other way
Reporting published on 12 October describes Real Estate Institute of Victoria analysis of September-quarter sale prices. Melbourne's overall median house and unit prices declined 0.7%, but the lower quartile—the bottom 25% of sale prices in a market—was stronger in many suburbs. 3
The reported examples are striking:
| Suburb | Reported lower-quartile sale-price level | Change over the year |
|---|---|---|
| Mornington | $920,000 | Approximately 12% higher |
| Caroline Springs | $735,000 | 11.4% higher |
| Glenroy | $796,000 | 10.2% higher |
| Frankston North | $640,000 | 8.5% higher |
These figures are REIV sale-price analysis as reported by realestate.com.au, not our own transaction-level research. The comparison runs from 30 September 2025 to 30 September 2026. 3
Two cautions stop this becoming misleading clickbait. First, “cheap” is relative: a $920,000 lower-quartile home is not an affordable option for every household. Second, a change in a quartile's sale-price level is not proof that the same individual homes appreciated by that percentage. The mix of properties sold can change.
Nor does this establish that every entry-level suburb is rising. It shows why a city-wide decline is a poor substitute for evidence about the actual segment you want to buy.
The other trap: a smaller price can still produce a bigger repayment
The RBA's 29 September decision raised the cash rate by 0.25 percentage points to 4.60%. The statement noted three earlier increases that year, acknowledged falling housing prices in most capitals and declining new housing loans, and still judged further tightening necessary because inflation remained too high.
Separate reporting on 11 October, citing Canstar modelling, puts the gross income needed for a median-priced Sydney house at about $245,000, and Brisbane at $185,000, up from approximately $160,000 a year earlier. These are model-dependent estimates, not universal salaries required by every bank or for every home. We have not independently reproduced Canstar's full model. 1
Here is a simpler, reproducible illustration. Assume a 20% deposit, a 30-year principal-and-interest mortgage, no fees and the following hypothetical mortgage rates—not the RBA cash rate:
| Scenario | Purchase price | Mortgage rate | Approximate monthly repayment |
|---|---|---|---|
| Starting point | $900,000 | 6.00% | $4,317 |
| Price falls 5%, rate rises 0.50 points | $855,000 | 6.50% | $4,323 |
| Price falls 10%, same higher rate | $810,000 | 6.50% | $4,096 |
In the middle scenario, a $45,000 price discount is almost entirely swallowed by the higher rate. The upfront deposit falls from $180,000 to $171,000, but the monthly mortgage payment is slightly higher. In the last scenario, the larger discount does reduce repayments. Rates do not erase every possible price saving.
This is a mathematical example, not a forecast or a lender quote. It excludes stamp duty, insurance, maintenance, other purchase costs and tax. The rate difference is an assumption, not a claim about what every bank has passed on.
Approval is a separate hurdle. Income, dependants, existing debt and the lender's assessment criteria still matter. Our borrowing-capacity explainer explains the difference between an actual repayment and the assessment used for approval.
How can entry-level homes resist a broader downturn?
There are plausible mechanisms, but the reported quartile figures do not isolate their contribution:
- Buyers can trade down. Reduced borrowing capacity can move demand from a larger house to a smaller one, or from an expensive suburb to a cheaper location.
- Suitable supply may be limited. A market can have more listings overall without many homes matching a particular buyer's budget and needs.
- Sale mix matters. Different sizes, conditions and locations within a suburb can change its reported sale-price distribution.
These are explanations to investigate, not proven causes of the specific suburb increases. Before declaring an entry-level boom, compare recent settled sales for similar homes—not just asking prices or a single median.
The wider downturn is real in the data we checked: NAB's October Housing Monitor reports combined-capital dwelling prices down 1.2% in September and 6.4% below their March peak. That is a different geography and measurement from Melbourne's quarterly sale-price medians. Both can be true without being interchangeable.
Where the Budget changes the equation—and where it doesn't
The 2026–27 Budget tax explainer describes reforms from 1 July 2027 that preserve negative gearing for new builds while restricting losses on affected established residential investments to offsets against residential property income, with excess losses carried forward.
It also specifies that properties held before 7:30pm AEST on 12 May 2026 are exempt from the negative-gearing changes. Separately, it sets out replacement of the 50% CGT discount with cost-base indexation and a 30% minimum tax on relevant real capital gains accruing after 1 July 2027, subject to transition rules and exemptions.
For an investor comparing an established home with a new build, those distinctions can change the expected after-tax holding cost. They do not mean every existing landlord loses deductions, and they do not set an owner-occupier's mortgage rate.
The Government presents the reforms as supporting first-home buyers and housing supply. But a policy objective is not proof that buying is immediately easier. Today's price, borrowing assessment and repayment still have to work together.
We cannot attribute a particular suburb's change—or a precise share of the national downturn—to the Budget from these sources. Read our Budget guide, then confirm the applicable rules with a registered tax adviser before modelling a purchase.
Is Australia worse than the US, Canada and Europe?
Australia's 4.60% cash rate is above the selected September benchmarks we verified: the US federal funds target of 3.75–4.00%, the ECB deposit rate of 2.50% and Canada's 2.25% overnight target.
But the Fed and ECB also raised rates at those September meetings; Canada held. “Australia hikes while everyone else cuts” would misdescribe those decisions.
More importantly for this story, a policy-rate gap is not an affordability ranking. Mortgage terms, fixed-rate periods, household incomes, deposits and purchase taxes vary across countries. A lower overseas benchmark does not tell us what a particular buyer pays.
For a defensible international house-price comparison, the OECD housing indicators distinguish nominal prices, inflation-adjusted prices and price-to-income measures. Without a verified same-period table using the same definition, we cannot call Australia the developed world's worst-performing housing market. Our international rate comparison covers the narrower benchmark comparison.
Before chasing a “bargain”, check these four numbers
- Comparable settled prices. Check the property type and price segment you actually want, rather than applying a city-wide percentage to the asking price.
- The full monthly cost. Include repayments, rates, insurance, maintenance and, where relevant, strata levies. Investors should also include vacancy and agent fees.
- A current borrowing assessment. Have your broker or lender update it after rate changes; an old pre-approval is not a permanent budget.
- The tax treatment of that asset. Investors should distinguish acquisition date, new versus established property and ownership structure. Our negative gearing calculator can help with illustrative cash flow, but should not be assumed to model every Budget transition rule.
Bottom line: the overlooked risk is not simply that prices fall further. It is that the home you can afford does not fall with the headline—and the bank still charges more to finance it. A cheaper market and an easier purchase are not the same thing.
Does a falling house-price index mean my target home is cheaper?
No. An index describes a wider market. Local sale prices, property types and price segments can move differently, and a suburb's sale mix can affect medians and quartiles.
Can higher rates outweigh a lower purchase price?
Yes, depending on the size of each change. In our illustrative 30-year loan with a 20% deposit, a 5% price fall combined with a mortgage-rate rise from 6.00% to 6.50% leaves repayments slightly higher. A larger price fall can still lower repayments.
