Westpac economists say the slump in house sales volumes during the past two months is a "strong signal" that prices are about to cool.
Latest Real Estate Institute figures showed that while the median price surged to a new high of $425,000 in November, the number of sales was down 6.6% compared with November 2012.
Westpac chief economist Dominick Stephens said that on a seasonally-adjusted basis, house sales fell 6% in November. He said that combined with October's decline, housing market turnover had now fallen 10% in the past two months.
In the latest edition of Westpac's Home Truths monthly housing update, Stephens said "the fact is", house sales bear a tight relationship with house price inflation (see chart below).
"Prices may be rising strongly right now, but the drop in house sales is a strong signal that prices are about to cool. We expect the rate of house price inflation will start slowing from early-2014."
Stephens said, however, the Westpac economists were "not suggesting that the sky is about to fall in".
"Our long-standing forecast is that house prices will rise 6.5% next year, compared to almost 10% this year. We have not changed that forecast."
Stephens said Westpac had "always said" that the Resrve Bank's restrictioins on high loan-to-value lending would "cause a short, sharp shock to the market" as the first home buyers dropped out.
"However, in time we expect investors will come into the market, limiting the fallout for prices."
Stephens said that rises in interest rates would eventually "prove a much more potent headwind for house prices".
"But it will take years for mortgage rates to throttle this market. It is not until 2016 that we expect high interest rates to cause house prices to decline."
In the mean time, Stephens said it was expected that the "ever-strengthening economy and inward migration" would remain "offsetting positive forces" for house prices during 2014.
