Rising Rates Drive Australian House Price Falls

The Reserve Bank of Australia’s decision to lift the cash rate to 4.60% in September has added further pressure to household borrowing capacity and housing affordability, even as property prices continue to soften across many parts of the country.

The RBA increased the cash rate by 25 basis points on 29 September 2026, with the new 4.60% rate taking effect from 30 September. The Bank said higher interest rates were needed to bring inflation back toward target, while also acknowledging that housing prices had fallen across most capital cities and new housing lending had declined noticeably.

Higher mortgage rates directly affect how much buyers can borrow. Because lenders assess home loan applications using serviceability buffers above the actual interest rate, even a relatively small rate increase can reduce the maximum loan available to a household.

For buyers in Melbourne’s western growth corridor, this means budgets may need to be reassessed before making offers. A household that previously qualified for a larger detached home may now need to consider a smaller property, townhouse, unit or a more affordable suburb within the corridor.

The impact is particularly significant for first-home buyers and households with smaller deposits, as they often rely more heavily on borrowed funds. Higher monthly repayments can also reduce the amount buyers are comfortable spending even when a lender is prepared to approve a larger loan.

At the same time, weaker borrowing capacity across the broader market can reduce competition. Buyers who have maintained strong financial positions and already secured updated loan pre-approval may find themselves competing against fewer purchasers than they would have during stronger market conditions.

This can create opportunities for buyers who are ready to act. Properties that remain on the market for longer may provide more time for building inspections, contract reviews and negotiation, particularly where sellers have adjusted expectations to reflect current conditions.

However, lower competition should not be confused with universally cheap property. Well-located and appropriately priced homes can still attract multiple buyers, particularly in areas with strong schools, transport links, employment access and limited supply.

For sellers in Melbourne’s west, the reduction in borrowing capacity means understanding what buyers can realistically finance has become increasingly important. Pricing a property according to previous market peaks may make it more difficult to achieve a timely sale.

Investors are also affected by the higher-rate environment. More expensive finance increases holding costs and can reduce cash flow, placing greater emphasis on rental yield, tenant demand and purchase price when assessing opportunities.

The RBA has acknowledged that tighter monetary policy is already contributing to weaker housing conditions. Scheduled mortgage repayments have risen to around 10% of household disposable income, close to their 2024 peak, illustrating the pressure higher rates are placing on borrowers.

For prospective buyers, the current market therefore presents both challenges and opportunities. Borrowing is more expensive and budgets are tighter, but softer prices and reduced buyer competition can improve negotiating conditions for financially prepared purchasers.

Pre-approved financing is particularly valuable in this environment because it provides buyers with a clearer understanding of their current borrowing limit. Buyers should still confirm that any approval remains valid after recent rate changes before committing to a purchase.

Melbourne’s western growth corridor continues to offer a broad range of property types and price points, allowing buyers to adjust their strategy without necessarily leaving the region. More affordable suburbs, townhouses and units may become increasingly attractive as borrowing capacity remains constrained.

Overall, sustained high interest rates are reshaping rather than eliminating property opportunities. Buyers with realistic budgets, updated finance approval and a clear understanding of local market conditions may be well positioned to take advantage of reduced competition while the broader housing market remains softer.
