Home prices across Australia's major cities slipped for a ninth straight month in June as tighter lending standards stifled investment demand in Sydney and Melbourne, a trend that seems unlikely to reverse anytime soon.

Property consultant CoreLogic said on Monday its index of home prices for the combined capital cities fell 0.3 per cent in June, after a 0.1 per cent dip in May.

That left capital city prices down 1.6 per cent for the year. Regional prices fared a little better with annual growth of 2.2 per cent, leaving prices for the combined markets down 0.8 per cent on June last year.

Along with tougher rules from regulators, lenders have also been raising borrowing standards amid revelations of widespread malpractice on loans and financial advice among several major institutions.
