Australian housing resale profits reached a 20-year high, with nearly 96% of property resales making a profit in the December 2025 quarter, Cotality said in a statement released on Wednesday.

The median gain hit a record AU$365,000, while the median loss inched up to AU$45,000, according to Cotality's Pain & Gain report.

The strength in resale outcomes is a product of sustained value growth over time, said Gerard Burg, Cotality Head of Research.

In December 2025, properties sold at a profit had a median hold period of 9.2 years, while those that recorded a loss had a median hold period of 8.2 years, according to the report.

Resale profitability outlook for this year is becoming more varied across markets with rising interest rates, rising listings in Sydney and Melbourne, as well as easing population growth, Burg said.
