Western Australia's land authority says new figures showing an increase in property activity reflects growing confidence in the state's housing sector.
Landgate's December report shows a 14 per cent increase in the number of documents lodged, compared to the same month in 2011.
Chief Executive Mike Bradford says the figures, which include house transfers, new mortgages and land releases, are part of a broader trend..
He says more people buying property could eventually help to ease W-A's tight rental market.
"I expect the gradual improvement in transaction levels to continue throughout this financial year and we anticipate 2013 will finish about 12 to 15 per cent above the previous year in terms of transaction levels," he said.
"I'm not sure we're yet to see a significant number of investors return to the market and that is certainly possible over the next few months.
"The sort of factors that contributed to an improved confidence from a buyers perspective have been lower interest rates and a shortage of rental properties."
