Family Loan Agreements and Home Loans in Sydney

A family loan agreement is a formal arrangement that allows family members to provide funds for a property purchase while meeting lender documentation requirements.

For self-employed company directors applying for a home loan in Sydney, demonstrating genuine savings and adequate deposit sources can be one of the most scrutinised aspects of the application. Lenders assess whether borrowed funds come from a legitimate source, whether repayment obligations affect your ongoing serviceability, and whether the agreement is structured in a way that meets prudential lending standards. A properly documented family loan agreement resolves each of these concerns and allows you to access finance that might otherwise be declined.

Why Lenders Require Family Loan Agreements to Be Documented

Lenders need to see that any funds you receive from family members are either a genuine gift or a loan with clear, sustainable repayment terms. If the funds are a loan, the lender must include the repayment obligation in your debt-to-income calculation and assess whether you can service both the home loan and the family loan simultaneously. Without a signed agreement, the lender cannot determine the repayment terms and will often treat the arrangement as either undocumented debt or request that the funds be converted to a gift.

Consider a company director purchasing in Sydney's Inner West. A parent provides $80,000 toward the deposit. The lender requests evidence that the funds are a gift, along with a signed statutory declaration from the parent confirming no repayment is expected. The director provides the declaration, and the lender accepts the deposit without adjusting serviceability. In the absence of that declaration, the lender would have assumed a repayment obligation and recalculated borrowing capacity based on an estimated monthly repayment, potentially reducing the approved loan amount.

What a Compliant Family Loan Agreement Must Include

A family loan agreement that satisfies lender requirements must specify the loan amount, the repayment schedule, the interest rate (which may be zero), the term, and the names of all parties. It should be signed and dated by both the borrower and the lender. If the loan is interest-free and has no fixed repayment schedule, this must be stated explicitly. Some lenders will accept an interest-free, no-repayment-schedule arrangement provided it is documented and the director's income can support the home loan independently.

In our experience, the most common mistake is preparing an agreement that is vague about repayment terms. An agreement that states "repayable when financially able" does not meet lender standards because it does not allow the lender to calculate a monthly commitment. If you cannot commit to a fixed repayment schedule, structure the arrangement as a gift or as a loan repayable on sale of the property, with a signed acknowledgment that no monthly payments are required.

How Family Loan Repayments Affect Serviceability and DTI Limits

Under APRA's debt-to-income lending limits, which have applied to all authorised deposit-taking institutions since 1 February 2026, lenders measure your total debt against your gross income. If your family loan agreement specifies monthly repayments, those repayments are included in your total debt. This can affect whether you fall within or above the DTI ratio of six times income, which is the threshold above which no more than 20 per cent of an ADI's new owner-occupier lending may be extended.

For a company director earning $150,000 in declared income, a family loan requiring $500 per month in repayments adds $6,000 to annual debt commitments. Combined with a proposed home loan repayment, this may push the total DTI above the threshold. Structuring the family loan as interest-free with repayment deferred until sale or refinance removes the monthly commitment and keeps the DTI calculation within acceptable bounds.

Gift Declarations Versus Loan Agreements

If family members are willing to provide funds without expectation of repayment, a statutory declaration confirming the gift is the most effective approach. The declaration should state the donor's name, the amount gifted, the date, and confirmation that no repayment is required. Both the donor and the recipient should sign. This removes any impact on your serviceability and allows the full amount to count as genuine savings or deposit, depending on how long the funds have been held in your account.

A director purchasing an established home in the Eastern Suburbs received $100,000 from a sibling. The sibling signed a gift declaration, and the funds were transferred into the director's offset account three months before application. The lender treated the funds as genuine savings because they had been held for more than 90 days and were evidenced by a clear gift declaration. Had the funds been provided as a loan, the lender would have required a formal agreement and adjusted the application to reflect the repayment commitment.

Structuring a Family Loan to Align with Lender Policy

When a gift is not appropriate and a formal loan is required, structure the agreement to specify either a fixed monthly repayment or repayment on a defined future event, such as sale of the property or refinance. If you choose a fixed repayment, ensure the amount is sustainable based on your current income. If you choose repayment on sale, obtain written confirmation from the family member that no payments are required in the interim, and include this in the loan agreement.

Some lenders will register the family loan as a second mortgage on the property title. This is not required by all lenders, but if the family member requests security over the property, the lender providing your home loan must be informed. The presence of a registered second mortgage affects the lender's position in the event of default and may result in a higher interest rate or reduced loan amount.

Using Family Loans Alongside the Australian Government 5% Deposit Scheme

The Australian Government 5% Deposit Scheme allows eligible first home buyers to purchase with a deposit of as little as 5 per cent without paying lenders mortgage insurance. Family loan funds can contribute to the 5 per cent deposit, provided the loan is documented and the repayment terms meet lender policy. In NSW, the property price cap is $1,500,000 in capital cities and regional centres including Sydney, Central Coast, Newcastle and Lake Macquarie, Illawarra, and other defined areas.

If the family loan is structured as a gift, the funds can be used to meet the minimum deposit requirement without any impact on serviceability. If the loan requires repayment, the lender must assess your capacity to service both the primary home loan and the family loan at the same time, and the combined commitments must meet the 3.0 percentage point serviceability buffer that applies to all new borrowing.

Tax and Legal Considerations for Family Loan Agreements

Family loans that charge interest may have tax implications for the lender, as interest income is assessable. Loans that are interest-free do not generate assessable income but should still be documented to avoid disputes. If the family member providing the loan is also a director or shareholder in your company, additional considerations may apply under Division 7A of the Income Tax Assessment Act 1936 (Cth), particularly if the funds originate from company retained earnings. We recommend speaking with your accountant before finalising any arrangement that involves related-party transactions or company funds.

For directors purchasing investment property, the source of the deposit does not affect the deductibility of interest on the investment loan itself, but any interest paid on a family loan used to fund the deposit is not deductible unless the family loan was used exclusively for income-producing purposes and meets ATO requirements.

Preparing Documentation Before You Apply

Before submitting a home loan application, ensure that any family loan agreement or gift declaration is signed, dated, and supported by bank statements showing the transfer of funds. Lenders will request evidence of the source of the donor's funds, particularly if the amount is large. If the donor is a parent, the lender may request recent bank statements or a letter from their accountant confirming they have the financial capacity to provide the funds without affecting their own financial position.

For self-employed applicants, lenders also assess your business financial statements, tax returns, and company structure as part of the overall application. A loan health check conducted before you apply can identify any gaps in documentation or serviceability and allow you to address them before formal submission.
