Higher borrowing costs, changing migration settings and a major shift in investor taxation are reshaping Australian housing. Falling prices may create opportunities, but affordability and supply remain unresolved.
Australia’s housing downturn has broadened, confronting buyers and owners with an uncomfortable combination: homes are losing value while borrowing remains expensive.
Cotality’s September Home Value Index recorded a 1.1% national monthly decline, the sixth consecutive fall. Values were 5.2% below their March 2026 peak. The question now is how higher interest rates, migration policy changes and new property tax arrangements will interact—and whether the adjustment produces more affordable housing or simply a more difficult market.

How far has the market fallen
September’s results show that the downturn extends beyond Sydney and Melbourne.
| Market | Change in dwelling values during September 2026 |
|---|---|
| Australia | −1.1% |
| Brisbane | −1.5% |
| Sydney | −1.4% |
| Melbourne | −0.7% |
| Darwin | +0.4% |
Darwin was the only capital to record a monthly rise. Sydney values were 8.6% below their February peak, while Melbourne was 7.2% below its November 2025 cyclical high.
These are changes in an estimated dwelling-value index, not a prediction for every individual home. Location, dwelling type and condition still matter. The dates also matter: a fall from a city’s own peak is different from its movement over the past month or year. Source: Cotality
Why cheaper homes can still be difficult to afford
On 29 September, the Reserve Bank increased the cash rate by 0.25 percentage points to 4.60%. It cited elevated inflation, global energy pressures and domestic capacity constraints, while acknowledging declining housing prices and a noticeable fall in new housing loans.

The implications for buyers run in opposite directions. A lower purchase price can reduce the deposit required and the amount borrowed. A higher mortgage rate increases the cost of servicing that debt and can reduce the loan a lender will approve.
A buyer therefore needs to compare the complete purchase budget rather than the advertised discount. Stamp duty where applicable, conveyancing, inspections, insurance, maintenance and strata costs remain part of the decision.
For existing owners, the immediate issue is often cash flow. A paper decline in value does not increase the outstanding loan balance, but it can reduce the flexibility to refinance, sell or access equity.
What the migration changes actually mean
Home Affairs says its latest policy package is designed to support net overseas migration forecasts of 245,000 in 2026–27 and 225,000 in 2027–28.
Announced measures include stronger visa compliance, action against student visa hopping, restrictions on secondary applicants for most student visas and a No Further Stay condition for visitor visas. The package also identifies priority skilled-visa processing for sectors including construction, healthcare and education. These are the government’s stated measures and forecasts; individual visa changes should be checked against their commencement and application rules. Source: Home Affairs
Net overseas migration is the balance of people arriving and leaving under the statistical residence rules. It is not the same as the permanent migration programme or the number of visas issued.
ABS figures for the year to March 2026 put net overseas migration at 292,100, down 5.6% from a year earlier. Total population nevertheless grew by 392,700, or 1.4%. Those are historical estimates, not a measure of the impact of September’s announcements. Source: ABS population release
Migration affects both demand and the capacity to build
Analysis: Slower population growth could moderate additional demand for housing, particularly in rental markets that receive substantial numbers of new arrivals. But a national migration forecast cannot be translated directly into a percentage fall in house prices.
Household size, where people settle, interstate movement, departures and the homes available in each area all affect the outcome.
There is also a supply-side consideration. Migrants include construction workers and other skilled employees. Policy that reduces demand while improving access to building skills could have a different housing effect from a broad reduction that also makes construction more difficult.
The useful indicators are therefore local vacancy rates, rent growth, household formation and dwelling completions—not migration numbers in isolation.
Foreign buyer restrictions are a separate policy
The government’s foreign-investment guidance says foreign investors are generally prohibited from purchasing established dwellings from 1 April 2025 until 30 June 2029, subject to limited exceptions. Its stated policy directs foreign residential investment towards additional housing supply.

This should not be described as a ban on all migrants buying Australian homes. Migration settings and foreign-investment eligibility answer different questions. A purchaser’s legal status and the type of property need to be assessed before a contract is signed.
Negative gearing changes have important transition dates
The ATO describes the 2026 negative-gearing and capital-gains reforms as law, with the principal changes applying from 1 July 2027. That distinction matters: legislation can already be enacted without its future rules yet applying. Source: ATO reform update
Under the Budget arrangements, qualifying new builds retain the ability to offset rental losses against other income. Established properties held before the Budget announcement retain their existing negative-gearing treatment.
For affected established properties acquired after the announcement, losses from July 2027 can instead offset residential-property income, with unused losses carried forward. They cannot simply be deducted against wages. Source: Budget tax reform overview
The detailed transition uses 7.30pm AEST on 12 May 2026 as the announcement cut-off. It includes properties already under contract but not yet settled. Established properties purchased between that announcement and 30 June 2027 can receive the existing treatment during that period, but do not secure permanent protection merely by being bought before July 2027.

Capital gains tax needs a separate calculation
The reforms replace the general 50% capital-gains discount for affected assets with inflation-based cost-base indexation and a minimum 30% tax on real capital gains from 1 July 2027. The Budget overview also provides a choice of the 50% discount or the new arrangements for investors in new builds. Source: Budget tax reform overview
Transition rules distinguish gains accrued before and after commencement. Treasury’s explainer describes valuation and apportionment methods for assets spanning that date. Negative-gearing grandfathering should therefore not be mistaken for a guarantee that every future capital gain receives the old tax treatment. Source: Treasury tax explainer
Analysis: Investors should model annual cash flow and eventual sale proceeds separately. A property can have manageable rental expenses but a different after-tax sale outcome. Ownership structure, acquisition dates, eligibility and exemptions require individual assessment; a headline tax percentage is not a complete calculation.
Falling sale prices do not guarantee lower rents
Analysis: Purchase prices reflect financing costs and the returns buyers expect. Rents reflect the availability of rental homes and what tenants can pay. Those markets interact, but they need not move together.
An investor selling to an owner-occupier removes a rental property, but if the buyer previously rented, it can also remove a household from rental demand. The outcome depends on who buys, who moves and whether additional homes are built. Claims that investor sales must always cause either falling rents or a rental crisis oversimplify the adjustment.
Supply remains a major constraint. The Productivity Commission’s July interim housing-regulation report identifies land-use restrictions and poorly coordinated infrastructure as obstacles to delivering homes where people need them. Its reform areas remain draft findings ahead of a final report, rather than completed nationwide policy changes. Source: Productivity Commission
How exposed are existing borrowers
The RBA’s October Financial Stability Review estimates that fewer than 1% of borrowers are in negative equity—owing more than their property is worth. Recent buyers with high loan-to-value ratios are more exposed, including some participants in the government’s 5% Deposit Scheme.
The RBA also tested a hypothetical further 20% uniform fall in prices. Around 5% of mortgages would enter negative equity in that exercise. That is a stress scenario, not the RBA’s house-price forecast, and it does not capture all wider economic consequences.
The distinction between equity and repayment capacity is crucial. A borrower can keep servicing a loan despite negative equity; financial difficulty becomes more serious when income or cash flow also deteriorates. Source: RBA Financial Stability Review
Three possible paths from here
The following scenarios are editorial analysis, not numerical forecasts.
| Scenario | Conditions that could produce it | Potential housing outcome |
|---|---|---|
| Gradual stabilisation | Inflation eases, borrowing costs stop rising and employment holds up | Price falls moderate, with recovery varying by location |
| A deeper downturn | Persistent inflation, further rate pressure or weaker employment | Lower borrowing capacity and more pressured sales prolong the correction |
| Continued affordability pressure | Population growth slows but construction also weakens | Sale prices soften while rents and the shortage of suitable homes remain difficult |
The indicators worth following are mortgage rates, unemployment, arrears, listings, local rents, vacancies and completed homes. The July 2027 tax transition adds another date for investors to monitor, but there is no reliable single date on which every Australian property market will turn.
What buyers and owners should consider
For owner-occupiers, the central question is whether the home meets their needs and remains affordable under less favourable conditions. An attractive discount is less useful if the repayments exhaust the household’s buffer.
For investors, assess rental income against realistic vacancy, maintenance, insurance, finance and tax costs. Compare new and established properties on their overall economics rather than choosing a new build solely for a tax concession. Construction timing, quality and settlement finance remain relevant.
For sellers, recent comparable transactions are more informative than the highest price achieved during a previous boom. For households staying put, a change in an online valuation does not by itself require a transaction.
Australia’s downturn is creating a different negotiating environment, but lasting affordability will depend on the interaction of incomes, credit, population growth and housing delivery. Lower prices can help the next buyer without resolving all of those pressures.
