The most probable outcome, assigned a 45% likelihood, is an orderly correction where house prices ease by 5 to 8% in Sydney and 7 to 10% in Melbourne. This scenario assumes that recent reforms to negative gearing and capital gains tax are absorbed without triggering panic selling, thanks to grandfathering provisions. However, a 35% probability is assigned to an extended pressure scenario. Should the Reserve Bank raise rates further, Sydney could see declines of 10 to 14%, while Melbourne faces sharper drops of 12 to 16% as investors rush to exit before stricter tax rules take effect in mid-2027.

Sydney dwelling values have already retreated 2.1% from their November peak to a median of $1,282,020, while Melbourne prices have fallen 3.2% from 2022 highs to approximately $995,000. Matt Proctor, Principal Analyst at PropCred, notes that the financial stakes are substantial, with a potential $90,000 difference in value for a $1.5 million Sydney property depending on which path the market follows. The industry will look to the spring listing season for clarity: clearance rates consistently below 53% in September would signal a deepening correction, while a recovery above 60% might support a soft-landing scenario with only minimal price adjustments.
