For many first home buyers, the biggest obstacle to homeownership isn’t income — it’s deposit. Saving a 20% deposit while paying rent in an expensive city can take a decade or more. A guarantor home loan is one of the most powerful tools available to help buyers get into the market sooner, without paying Lenders Mortgage Insurance (LMI).
What Is a Guarantor Home Loan?
A guarantor home loan involves a third party — usually a parent or close family member — using equity in their own property to guarantee part of your loan. This allows you to borrow more than your deposit alone would support, and in many cases eliminates the need for LMI entirely.
For example: you want to buy a $700,000 home but only have a $35,000 deposit (5%). Without a guarantor, you’d need to pay substantial LMI. With a parent guarantor providing a $105,000 guarantee against their own property, you effectively have a 20% deposit for LMI purposes — paying none.
How Does the Guarantee Work?
The guarantor doesn’t actually hand over money. Instead, they agree that if you default on your loan, the lender can recover the guaranteed portion from their property. This is why it’s critical that both you and your guarantor understand the risks involved.
The guarantee is typically limited to a specific dollar amount (a “limited guarantee”) rather than your entire loan. Once you’ve built sufficient equity — typically reaching 80% LVR — the guarantee can be released, and your guarantor’s property is no longer at risk.
Who Can Be a Guarantor?
Most lenders require the guarantor to be an immediate family member — parents are most common, but siblings, grandparents, or children may also be accepted depending on the lender. The guarantor must: own property in Australia with sufficient equity, be an Australian citizen or permanent resident, meet the lender’s credit criteria, and generally be under a certain age (often 65–70 at the end of the loan term).
Risks for the Guarantor
Being a guarantor is a significant financial commitment. If the borrower defaults and can’t repay the loan, the lender can pursue the guarantor and, in a worst case, force the sale of the guarantor’s property. This is why many lenders require guarantors to obtain independent legal advice before signing.
In practice, guarantor loans rarely result in guarantors losing their homes — defaults are uncommon and lenders exhaust other options first. But the risk is real and guarantors should only proceed if they’re confident in the borrower’s ability to manage the loan.
Releasing the Guarantee
Once you’ve repaid enough of your loan (or your property has grown in value) to bring your LVR below 80%, you can apply to have the guarantee released. This typically requires a new property valuation and formal application to your lender. Most guarantors see their guarantee released within 3–7 years.
Alternatives to a Guarantor Loan
If a guarantor isn’t available, other options include the First Home Guarantee (government scheme allowing 5% deposit with no LMI for eligible buyers), the Family Home Guarantee (for single parents with a 2% deposit), or simply saving a larger deposit. A broker can help you compare all options.
