A scheme to help people take their first step onto, or move up, the property ladder is being introduced in Wales in Spring.
The three-and-a-half-year scheme will be available to all buyers facing housing pressures.
£27m from the Welsh Government will support the purchase of up to 3,000 new-build homes up to the price of £250,000.
Buyers will not be able to claim the funding directly, instead house builders and the government will act as guarantors. Buyers will contribute a 5% deposit.
The mortgage guarantee scheme could allow an investment in housing of up to £500m within a three year period.
Huw Lewis, the Housing Minister, said the scheme was "excellent" news for potential house buyers, which would "boost house building," "create jobs" and "stimulate growth".
