RBA warns of future apartment oversupply

THE Reserve Bank says an oversupply of apartments poses a risk to household finances and the country's overall stability.

The RBA's biannual Financial Stability Review says a surge in apartment building in Sydney, Brisbane and Melbourne could bring down prices and rents in the coming year.

"If that occurs, investors will need to service their mortgages while earning lower rental income and any households facing difficulties may not be able to resolve their situation easily by selling the property," the report said.

For now, things are stable.
