Australian property prices have fallen through 2025, but the correction hasn’t brought the market back to historical fair value by at least one widely-watched metric. The question now: how much further would prices need to drop, and does that change your buying decision?
Which valuation measure we’re talking about
The most common gauge is the price-to-income ratio: median dwelling price divided by median household income. When that ratio climbs above its long-run average, property is considered overvalued relative to what households can afford. When it falls below, it’s undervalued.
Australia’s national ratio sat around 5.5× in the early 2000s. By 2021 it had stretched past 8×. Even after 2025’s price falls, preliminary data suggests the ratio remains above 7× in major capitals, still elevated by historical standards.
Other measures exist: price-to-rent (yields), replacement cost, real prices adjusted for inflation. But price-to-income is the one policymakers and economists cite most often when discussing affordability and valuation risk.
Key numbers
- National price-to-income ratio peaked above 8× in 2021
- Current ratio estimated around 7–7.3× in Sydney and Melbourne
- Long-run average sits closer to 5.5–6×
- A return to that average would require a further 15–20% price decline from current levels, all else equal
What drives valuation back toward fair value
Three paths: prices fall further, incomes rise faster than prices, or time passes while both adjust slowly. The mix matters.
If mortgage rates stay elevated and credit growth weak, prices face downward pressure. If wage growth picks up and rates eventually fall, incomes do the work and prices stabilise or edge higher without the ratio worsening.
Historically, Australia has solved overvaluation through a combination: prices stall or dip modestly, wages grow, and the ratio compresses over years rather than months. Sharp corrections have been rare outside recessions or credit crunches.
The 2025 scenario sits somewhere in between. Rates are high but not rising further, employment is softening but not collapsing, and price declines have been orderly so far. That points to a slow grind rather than a crash.
The practical take for buyers
Waiting for textbook fair value means waiting for an outcome that may not arrive, or may take years. If your horizon is long, seven-plus years, and you can service the loan comfortably today, short-term valuation gaps matter less than whether the property fits your needs and whether you can hold through a cycle.
If you’re stretching serviceability now or banking on quick capital growth, the valuation risk is real. A market trading above historical norms has less upside cushion and more downside if rates stay higher for longer or unemployment ticks up. Falling property prices vs rising rate risk: the math that matters walks through that trade-off in detail.
For investors, elevated valuations hit yields twice: higher entry prices and thinner rental returns. Compare gross yields in your target suburb against the long-run average, if they’ve compressed below 3% in a capital city, you’re buying expensive by income standards. Second investment property: where serviceability replaces savings covers how that affects borrowing capacity on a second purchase.
What could shift the dial
Three scenarios over the next 12–18 months:
-
Base case: Rates hold or ease slightly, wages grow 3–4%, prices drift down another 3–5% in Sydney and Melbourne, ratio compresses slowly. Buyers face a marginally better entry point but no step-change.
-
Upside (for sellers): RBA cuts faster than expected, credit growth rebounds, prices stabilise or lift 2–3%. Ratio stays elevated, affordability worsens again.
-
Downside (for owners): Unemployment rises above 4.5%, forced sales increase, prices fall another 8–12%. Ratio corrects faster but buyer confidence stays weak.
None of these paths deliver a swift return to long-run fair value. The ratio took a decade to climb this high; unwinding it will take time unless a shock forces the issue.
Red flags in the next six months
Watch auction clearance rates in Sydney and Melbourne. If they fall below 50% and stay there, it signals weak demand and more price pressure ahead. Rising listings without matching buyer activity points the same way.
Monitor wage data from the ABS. If household income growth stays below 3% while mortgage costs remain elevated, the affordability squeeze tightens and the valuation gap persists.
RBA commentary on the labour market matters. If they signal concern about rising unemployment, rate cuts may arrive sooner but property sentiment could weaken before the cuts help.
One clear next step
If you’re deciding whether to buy now or wait, model your own version of fair value for the specific property. Take the asking price, compare it to similar sales 12–18 months ago, check the rental yield, and stress-test your repayments at 6.5%. If the numbers work at that rate and you’re prepared to hold for a full cycle, valuation debates matter less. If they don’t, wait.
