The Treasurer said talk of a bubble in the property market was "lazy analysis" and ignored supply issues.
House prices have risen more than 10 per cent in the past year, according to property research business RP Data, while Sydney prices have risen almost 24 per cent in two years.
Former treasurer Peter Costello told the property forum that he believed it was state government taxes on the release and transfer of land that were restricting supply.
"Building a house is comparatively cheap," he said. "What is expensive in Australia is land.
"So we have an increasing demand but we have quite a restrictive supply of land."
Mr Steinhart said each of Australia's major metropolitan cities faced supply issues, though the situation was most pronounced in Sydney.
But he said Australians shouldn't expect the recent housing market boom to continue and prices would grow at much more moderate rates in the next few years. He expects Sydney prices to rise by about 5 per cent a year, while Brisbane and Melbourne will likely rise by 4.5 and 3.5 per cent respectively. AAP
