Westpac has launched a service allowing family members to help first-home buyers into properties.
The move comes ahead of restrictions that will make it tougher to get a loan for those with a low deposit.
In the next two months, banking experts expect the Reserve Bank to introduce loan-to-value ratio restrictions on banks to try to ensure the financial system is not threatened by high-risk lending practices.
A loan-to-value ratio of, say, 80-20 would mean a minimum deposit of 20 per cent of the property's value would be required before a bank could lend. Westpac said it had in the past allowed borrowers to use the equity of third parties to raise money but that its new "family springboard" service would formalise and streamline the process.
The bank will allow prospective home owners to borrow against the equity in the property of an immediate family member, or their savings, to reach the required deposit.
