The Easiest Way to Structure a Family Loan Agreement

What Is a Family Loan Agreement for a Home Loan?

A family loan agreement is a formal written contract between you and a family member who's lending you money for a deposit or settlement costs. The agreement needs to specify the loan amount, repayment terms, interest rate (even if it's zero), and security details in a way that satisfies both your lender and the ATO.

In Clayfield, where buyers are often competing for character homes and newer townhouses in a tightly held market, family assistance with a deposit can make the difference between securing a property or missing out. But lenders want to see that the money is genuinely a loan, not a gift that might need to be repaid suddenly, and they'll ask for documentation that proves the arrangement is sustainable.

Why Lenders Care How Family Loans Are Documented

Lenders assess family loans as part of your total debt position. If the loan has monthly repayments, those repayments reduce your borrowing capacity the same way a car loan or personal loan would. If the family loan has no formal repayment schedule, some lenders will add a notional monthly repayment to your liabilities anyway, typically calculated at around 3% of the loan amount annually, divided by twelve.

Consider a buyer who borrows $50,000 from parents to help with a deposit on a Clayfield Queenslander. If the family loan agreement shows no repayments for five years, the lender might still assume a monthly commitment of around $125 when calculating serviceability. If the agreement specifies $500 per month in repayments, that $500 becomes part of your ongoing liability and will affect how much you can borrow. The documentation you provide shapes how the lender models your capacity to service the mortgage.

The Three Documents Lenders Will Ask For

You'll need a signed loan agreement, a statutory declaration from the family member, and evidence of how the funds were transferred. The loan agreement should include the amount, the term, the repayment schedule, whether interest applies, and what happens if circumstances change. The statutory declaration confirms that the family member understands the arrangement, has the financial capacity to lend the money without hardship, and won't demand early repayment.

Most lenders also want to see that the funds came from the family member's verified savings or the sale of an asset, not from another borrowed source. If your parents are refinancing their own home to lend you the deposit, some lenders will want to see that their loan serviceability isn't compromised by the new debt.

How Repayment Terms Affect Your Home Loan Application

The structure of your repayment terms directly affects your home loan approval. A family loan with interest-only payments, or no payments at all until the property is sold, will generally have less impact on serviceability than a loan requiring $400 per week in principal and interest repayments.

In our experience, buyers often assume that setting the family loan as interest-free with no repayments for ten years is the most helpful structure. Sometimes it is. But if that arrangement pushes your total liabilities high enough that the lender applies a buffer or declines the application altogether, you're better off with a modest monthly repayment that keeps your debt position manageable and demonstrates you can service all commitments.

Does a Family Loan Need to Charge Interest?

No, but the tax treatment changes depending on whether interest is charged and whether it's at a commercial rate. If a family member lends you money at zero interest, there's no requirement to charge interest for the loan to be valid. But if the loan is large and long-term, the ATO may treat any unpaid interest as a gift, which can have implications for the lender's estate and for capital gains tax if the family member later forgives the debt.

If your family member does charge interest, the rate should be documented clearly. The interest they receive is assessable income and must be declared on their tax return. If the loan is used to purchase an investment property, the interest you pay may be tax-deductible, but only if the funds were used for an income-producing purpose. For an owner occupied home loan, the interest you pay on a family loan is not deductible.

What Happens If the Family Loan Is Secured Against the Property

Some family members want their loan secured by registering a second mortgage or caveat over the property. This gives them a legal interest in the property if you default, but it also creates complications when you apply for finance. Most lenders will only lend up to a certain loan-to-value ratio when a second mortgage is registered, and some lenders won't lend at all if another party holds security over the title.

If you're buying in Clayfield and planning to use a family loan as part of your deposit, it's worth discussing whether security is necessary before the loan agreement is signed. Unsecured family loans are far more common and much easier to work with when structuring a mortgage. If the family member insists on security, expect your pool of available lenders to shrink and your interest rate to reflect the additional risk.

How a Family Loan Agreement Differs from a Gift Letter

A gift letter states that the funds have been given to you with no expectation of repayment. A family loan agreement states the opposite: the funds must be repaid according to the agreed terms. Lenders treat these two documents very differently. A genuine gift increases your deposit and has no impact on your liabilities. A loan increases your liabilities and may reduce the amount you can borrow, depending on the repayment structure.

Some buyers try to present a loan as a gift to avoid the serviceability impact, then make informal repayments later. That's fraud. Lenders verify large deposits, and if the funds came from a family member, they'll ask for a statutory declaration clarifying whether it's a gift or a loan. Misrepresenting a loan as a gift can result in your loan being recalled, and it puts your family member in a difficult position if the lender later requests updated information.

Setting Up a Family Loan That Works for Your Lender and the ATO

The agreement should be written, signed, dated, and specific. Include the full names of both parties, the loan amount, the date the funds were transferred, the term of the loan, the repayment amount and frequency, the interest rate, and what happens in the event of financial hardship, sale of the property, or death of either party. You don't need a lawyer to draft the agreement, but having one review it is often worthwhile, particularly if the loan is over $100,000 or involves multiple family members.

Keep records of every transfer and repayment. If the ATO or your lender ever questions the arrangement, a clear paper trail is your strongest evidence that the loan is genuine. If you're making repayments in cash, document them with a receipt or a note in both parties' records. If you're making repayments by bank transfer, keep the transaction history.

When a Family Loan Makes Sense and When It Doesn't

A family loan works when it gets you into a property sooner, avoids Lenders Mortgage Insurance, or bridges a temporary savings gap without creating unmanageable debt. It doesn't work when the repayments stretch your budget so thin that you can't service the mortgage, or when the terms are so vague that your lender won't accept the arrangement.

In a scenario like this: a buyer wants to purchase a townhouse in Clayfield and has saved $60,000, but needs $80,000 to reach a 10% deposit and avoid LMI on a property at the upper end of the precinct's townhouse range. A parent offers to lend $20,000 with repayments of $100 per month over ten years at zero interest. The buyer provides a signed loan agreement, a statutory declaration from the parent, and bank statements showing the transfer. The lender accepts the arrangement, factors the $100 monthly repayment into serviceability, and approves the loan. The buyer secures the property, avoids LMI, and repays the family loan gradually without financial strain.

That outcome depends entirely on the quality of the documentation and the honesty of the arrangement. If the buyer had presented the $20,000 as a gift but signed a private agreement to repay it, the loan would have been based on false information. If the family loan had required $500 per month in repayments, the buyer's serviceability might not have supported the mortgage at all. The structure matters as much as the amount.
