Mirvac Group's Susan Lloyd-Hurwitz forecasts Sydney's fast house price growth is close to ending.
And she anticipates volumes of home sales could fall away by 15%.
"Previous cycles would suggest that activity, i.e. volume of sales, will moderate for a year or two by 15%, but importantly we don't believe this will lead to price falls rather we expect price growth to moderate away from the double-digit growth rate that it has been experiencing."
She suggested the recent Australian Prudential Regulation Authority crackdown had been a "blunt" measure.
Ms Lloyd-Hurwitz has presided over a record $2 billion in residential sales in the past year at Mirvac.
