Since then, Barfoot & Thompson’s clearance rate has plummeted, according to Sykes, prolonging sales times and sending prices lower.

“In an ideal world, you’ll get a bit of froth blown off the top [of house prices] and everything is fine.

But even a modest a fall in house prices will knock confidence, causing homeowners to cut back on spending.
A slowdown in activity will also deal a blow to many other parts of the economy because of the housing market’s links to builders, lawyers, banks, moving companies and furniture stores, to name a few.
“An additional negative factor, compared to the [global financial crisis], is that the Chinese housing market is also in a downturn,” according to Slater.
“So rather than offsetting the impact on world output of a global housing downturn, as was the case after the GFC, the Chinese housing sector is contributing to the slump.”— Laura He contributed to this report.
