How to Structure a Family Loan Agreement for Home Loans

Your family wants to help you get into a property.

Borrowing from parents or having them guarantee part of your loan can get you into a home years sooner, especially when you're on shift work and saving a deposit between rosters feels like you're getting nowhere. The part that goes wrong is when no one writes down who's responsible for what.

What a Family Loan Agreement Actually Does

A family loan agreement is a legal document that sets out the terms when a parent or relative lends you money or guarantees your home loan. It covers the loan amount, repayment terms, interest rate (even if it's zero), and what happens if circumstances change. When drafted properly, it protects both you and your family member by making expectations clear before money changes hands.

Consider a FIFO worker borrowing $40,000 from his parents to cover the deposit on an owner occupied home loan. Without a written agreement, the parents might expect monthly repayments starting immediately. The son might assume he'll pay them back when he sells the property in five years. That gap in understanding destroys relationships. A family loan agreement removes the guesswork.

Why Lenders Want to See Documentation

Banks treat undocumented family money with suspicion. If $50,000 appears in your account three weeks before settlement and you can't prove it's a genuine gift, the lender will assume it's a loan and adjust your borrowing capacity downward to account for those repayments. A signed family loan agreement confirms the terms, which lets the lender assess your actual position. If the money is a genuine gift with no repayment obligation, you'll need a statutory declaration from the person giving it, stating exactly that.

This matters when you're applying for a home loan as a FIFO worker because lenders already scrutinise irregular income patterns. Adding unexplained cash movements gives them another reason to tighten serviceability.

Interest Rates and Tax Implications

You can structure a family loan with zero interest, but the Australian Taxation Office has views on what that means. If your parents lend you a substantial amount interest-free and you use it to purchase an investment property, they're technically foregoing income they could have earned elsewhere. That can trigger tax considerations, particularly if the loan runs for years. For an owner-occupied purchase, the tax treatment is simpler, but you still want the agreement to state the interest rate clearly, even if it's zero.

In our experience, parents who charge a nominal rate of 2-3% often feel more comfortable with a formal arrangement, and it makes the loan look more legitimate to lenders when you're applying for a home loan. The rate doesn't need to match bank rates, but documenting it avoids confusion.

Guarantor Loans Versus Direct Family Loans

A guarantor loan involves a family member using their property as security to cover part of your loan, which lets you borrow up to 105% of the property value and avoid Lenders Mortgage Insurance. The guarantor doesn't hand over cash, they pledge their equity. A direct family loan means they give you money, you deposit it, and you repay them separately from your mortgage.

Both approaches reduce the deposit you need to save, but the risk sits in different places. With a guarantor loan, your parents are on the hook if you default, but they don't lose cash upfront. With a direct loan, they've parted with money immediately, and if your circumstances change, recovering it can turn into a legal dispute.

As an example, a FIFO mobile plant operator used a guarantor arrangement where his mother guaranteed $60,000 of his loan using her paid-off home in regional Queensland. He paid down the guaranteed portion within three years, the guarantee was released, and his mother's property was never at risk because he kept up repayments. That outcome relied on him maintaining steady income through his roster and prioritising the guaranteed portion in his repayment strategy.

What Goes Into the Agreement

The agreement needs to specify the exact loan amount, the repayment schedule (weekly, monthly, lump sum), what happens if you sell the property, and what happens if either party dies or becomes unable to meet obligations. It should also cover whether the loan is secured against your property or unsecured, and whether repayments are required if you lose your job or go on extended leave.

For FIFO workers, adding a clause that adjusts repayments during unpaid leave or roster changes can prevent default. If you're earning $8,000 a fortnight on a two-weeks-on, one-week-off roster and suddenly move to a three-and-one with lower day rates, your capacity to meet a fixed monthly repayment drops. Building flexibility into the agreement acknowledges that reality without leaving things vague.

When the Loan Needs to Be Registered

If the family loan is secured against your property, it may need to be registered on the title as a second mortgage. That registration costs money and involves a solicitor, but it gives your family member legal priority if the property is sold or if you refinance. An unsecured family loan doesn't appear on the title, but it also means your relative has no claim on the property if things go wrong.

Most family loans for deposits remain unsecured because the amounts are smaller and the relationship is informal. But when parents contribute $100,000 or more, registering the loan protects their position. Speak to a solicitor about whether registration makes sense in your situation, particularly if you're planning to refinance within a few years.

Getting the Agreement Drafted

You can download a template online, but paying a solicitor to draft or review the agreement is worth the $500 to $1,000 it costs. A lawyer ensures the document is enforceable, covers all necessary clauses, and complies with Australian consumer credit laws if the lender is a natural person. If your family loan is substantial enough that default would cause genuine financial harm to the lender, the agreement needs to be airtight.

FIFO income can look unpredictable on paper, and lenders already apply loadings or discounts to your reported income. A poorly drafted family loan agreement can make your application harder to assess, while a clean one helps the lender see exactly what you owe and to whom.
