For many Australians, saving a 20% deposit while renting can delay the dream of homeownership by several years. Guarantor home loans could offer a way to fast-track your property journey by allowing a family member to use the equity in their own home as added security for your loan. This can reduce or eliminate your needed deposit and may help you avoid costly Lenders Mortgage Insurance (LMI), bringing you closer to buying a home sooner than you might expect.

Think of it this way: a guarantor loan lets someone you trust (usually Mum or Dad) use the equity in their home to help you get your foot in the door. They’re not giving you cash—they’re backing your loan with their property as extra security.
Here’s the setup in plain English:
Saving 20% can take years—especially when rent keeps eating into your savings. With a guarantor, you could buy next year instead of in five years.
LMI can cost you tens of thousands when you have a small deposit. Using a guarantor often means you can avoid this cost entirely—that’s money that stays in your pocket.
The extra security means you might qualify to borrow more, which could help you buy in the area you actually want to live in rather than settling for something further out.
Got a solid job but not much in the bank? That’s okay. If you can afford the repayments, a guarantor loan could still work for you—some lenders will even approve 100% of the purchase price.
Once you’ve built up enough equity (usually 10-20%), you can apply to remove your guarantor and fly solo. This typically happens through refinancing or a simple loan review.
Real talk: Guarantor loans aren’t without their downsides. Both you and your guarantor need to go in with eyes wide open.
If you can’t make your repayments, your guarantor has to step in. In a worst-case scenario, they could be forced to sell their home to cover your debt. That’s a big deal.
While they’re guaranteeing your loan, your guarantor’s ability to borrow for their own needs—like renovating or investing—gets limited because of the liability on their shoulders.
The guarantee shows up on your guarantor’s credit file, which could affect future loan applications or credit cards they might want.
Money and family don’t always mix well. Before anyone signs anything, make sure everyone’s on the same page about expectations, risks, and what happens if things don’t go to plan.
Lenders will insist your guarantor gets independent legal and financial advice before committing. This protects everyone by making sure the decision is fully informed.
Lenders are pretty specific about who qualifies. Here’s what they typically look for:
Having a guarantor helps, but you still need to qualify on your own merits:
Good news: your guarantor doesn’t stay attached to your loan forever. Here’s how the release process usually works:
Build equity, gain freedom: Once you’ve paid down your loan or your property value increases enough to give you 10-20% equity, you can request to release your guarantor.
Absolutely. Refinancing a guarantor loan is common and often smart. Here’s why people do it:
