How Many Homes in Australia Might Need to Be Sold if Mortgage Rates Continue to Rise in the Second Half of 2026?

SYDNEY, NSW – 6 Aug, 2026 – As of early August 2026, the Reserve Bank of Australia’s cash rate sits at 4.35% after three hikes earlier in the year. Variable mortgage rates for many borrowers remain in the high 5% to low 6% range. The central question for many households is stark: if rates rise further in the second half of 2026, how many homes could be forced onto the market?

The short answer is that while mortgage stress is already elevated, widespread forced selling on a catastrophic scale remains unlikely — though tens or even hundreds of thousands of households sit close to the edge.

Current Mortgage Stress Snapshot

Recent data paints a clear picture of pressure:

  • Roy Morgan research shows around 29–30% of mortgage holders (approximately 1.54–1.6 million people) are now considered at risk of mortgage stress. A further rate rise to 4.60% was modelled to push this closer to 1.6 million.
  • Digital Finance Analytics data indicates more than 421,000 households across the 80 hardest-hit postcodes were in mortgage stress by the end of June 2026 — a sharp quarterly rise.
  • Stress has spread beyond traditional outer suburbs into some blue-chip areas of Sydney, Melbourne and other capitals.

A Finder survey earlier suggested that a rate hike could push as many as 9% of property owners (potentially up to around 290,000 households) toward selling, with another cohort saying two further hikes would force their hand.

Will Further Rate Hikes Actually Happen?

Most major banks and economists now expect the RBA to hold the cash rate at 4.35% through the remainder of 2026, with the first cuts more likely in 2027. Cooler recent inflation readings have reduced the probability of another hike, although the RBA continues to keep the option open if inflation reaccelerates.

If rates do rise further, the impact would be felt most acutely by:

  • Recent first-home buyers with small deposits
  • Highly geared investors affected by the 2026 negative gearing and CGT changes
  • Households that stretched their budgets during the previous lower-rate environment

Why Widespread Forced Sales Are Still Unlikely

Despite rising stress, several factors continue to limit a wave of distressed selling:

  • Most homeowners still hold substantial equity buffers after earlier price growth.
  • Loss-making resales remain relatively rare in many markets.
  • Households often respond by cutting discretionary spending, drawing on savings, refinancing, or switching to interest-only arrangements before selling.
  • Strong population growth and ongoing housing shortages provide underlying demand support.

Experts note that any further downturn is more likely to be driven by weaker buyer demand than by a surge in forced vendor activity.

What This Means for the Market in Late 2026

Even without further rate rises, higher servicing costs and tax changes are already cooling demand. Forecasts from major firms point to flat-to-modestly declining national prices for the full year 2026, with steeper falls expected in Sydney and Melbourne. A further hike would amplify that softness and increase the number of stressed sellers, particularly in more recent purchase cohorts.

Practical Takeaways

  • Borrowers close to the edge should stress-test their finances now and speak to their lender early.
  • Buyers may find more negotiating power as some vendors become motivated.
  • Long-term fundamentals (supply shortages and population growth) still favour patient holders of quality assets.

Final Thoughts from the Editor’s Desk

There is no precise number of homes that “must” be sold if rates rise further — the outcome depends on how high rates go, how long they stay elevated, and how unemployment evolves. What is clear is that mortgage stress is already significant and would intensify with any additional tightening.

The Australian housing market has so far avoided a disorderly forced-sale cascade thanks to equity buffers and adaptive household behaviour. That resilience is being tested. Smart buyers and owners will plan for a higher-for-longer environment rather than hoping for rapid rate relief.

At Smart Buyer Agent, we help clients navigate these pressures — whether that means securing value in a softer market or restructuring existing holdings.
