With more first home buyers relying on family support to get into the market, we explain why it may be beneficial to put the details in writing if Mum and Dad offer a financial helping hand.

Higher home prices are seeingmore first homebuyers turn to family membersfor help buying a place of their own.

That support can come in a variety of forms, including living at home rent-free to help grow a deposit, or having parentsact as guarantorfor a first home loan.

But it can also go one step further.

An estimated60% of first homebuyers have dipped into the ‘Bank of Mum and Dad’– receiving financial assistance from parents – to get started in the market.

The amounts handed over aren’t small,averaging more than $30,000according to one study.

With that sort of money changing hands, it can be worth having a written agreement in place.

As many as64% of first homebuyers who rely on the support of parentshave no paperwork at all for the arrangement, which can make things complicated with lenders.

Let’s take a look at why it’s worth considering putting the details in writing.

The Bank of Mum and Dad can help fast-track homebuying plans

In general, parents provide funds to their first-home-buying children as a loan, a gift or an early inheritance.

For first homebuyers, this injection of cash can cut the time taken to save a deposit, or push a deposit up to 20% – the amount usually required to avoidlenders mortgage insuranceif you’re not relying on any federal government or lender schemes.

A bigger deposit may also have the upside of giving buyers access to lower interest rates.

How do lenders treat funding from Mum and Dad?

If you’re expecting Mum and Dad – or other close relatives – to offer cash towards buying a first home, it’s likely your lender will askwhether the money is a gift or a loan.

This distinction matters because if the money is a loan, the bank may take the repayments to parents into account when considering your ability to service a home loan.

This could even impact your borrowing power.

That said, research shows nearly half (49%) of parents who provide financial assistance to their childrendo not expect to be repaid.

More than a quarter (26%) offer the money as a gift.

Even so, having these details set out in writingbeforeapplying for a home loan can answer a lender’s questions about funding sourced from Mum and Dad, and help prevent delays in your loan application.

A new reason to have a written agreement

New anti-money laundering lawsin place from 1 July 2026 mean that real estate agents are now required to verify the identity of home buyers, and in some cases, ask about where thefunds used to buy a homecame from.

Here too, it can be handy to have a written document that describes the nature of support from parents.

What documentation is required?

It depends on the type of arrangement.

If the money is a gift, a statutory declaration signed by your local Justice of the Peace (JP) confirming there’s no repayment expected is usually enough.

For anything more, such as the money being a loan or your parents acting as guarantor, you’ll want to seek legal advice from your solicitor.

A few tips for first homebuyers to bear in mind

The financial assistance of family members can give first homebuyers a valuable leg-up with a deposit.

But your deposit is just one part of the picture.

Lenders usually want to see that you’ve been regularly setting money aside in savings – usually for at least three to six months.

This evidence of ‘genuine savings’shows you have the discipline to manage a home loan.

Also, your personal income still does a lot of the heavy lifting in determining if you’re eligible for a home loan.

After all, family members may provide a generous helping hand to get you started, but you need to be able to live comfortably with your loan over the long term.
