CBA's housing prices measure recorded an increase of 23 per cent nationally in the 12 months to March 2003. The continued strength in the housing market was due to low interest rates, consumer expectations, a competitive lending market and the relative unattractiveness of other investment options, a spokesman said. Low-income earners and first-home buyers would probably cope with higher interest rates but people who entered the housing market late would be most at risk if conditions change, he said.
