PERTH home sellers are increasingly achieving more than their asking price, with new data showing the trend has reached record levels.

Real Estate Institute of Western Australia (REIWA) figures revealed that in the final three months of 2025, only 9.9 per cent of houses sold for less than their advertised price.

REIWA president Suzanne Brown said the result was unprecedented.

“Discounting levels did not reach these lows during the last two booms,” she said.

“During 2013 and 2014, 44.3 per cent and 46.3 per cent of houses respectively sold for less than their listed price.

“During the 2006 boom, the level of discounting was 49.0 per cent.”

The current market conditions are being driven by low housing supply and strong buyer demand.

New listings fell below the long-term average in the second half of 2025, while buyer numbers remained high.

Homes were selling in as little as eight days in September and October, marking record-low selling times.

Ms Brown said when demand outweighs supply, prices are pushed higher.

On average, houses sold for 6.5 per cent more than their asking price during the quarter.

For a home listed at $700,000, this equates to a sale price of about $745,500.

Ms Brown said this was the strongest result on record, surpassing the 2006 boom where homes sold for an average of 3.2 per cent above asking price.

She said even during the strong 2013–14 market, homes generally sold slightly below their advertised price.

“This really is a very unique time in the market,” she said.

However, she warned sellers not to expect the same outcome in every case.

“Every sale is different, and this average shouldn’t create an expectation from sellers,” she said.

Ms Brown also addressed concerns about underquoting, where properties are advertised below their expected sale price.

“While current market dynamics will see the majority of houses sell at or over the listed price, I remind people that underquoting is illegal,” she said.

“If anyone has genuine evidence an agent has deliberately underquoted the price of a property, I would ask them to report the agent to Consumer Protection.”
