Saving a 20% deposit is the hardest part of buying a first home. A guarantor home loan can be a way around it — here's how it works.
A guarantor (usually a parent) uses the equity in their own home as extra security for your loan. They don't hand over any cash, and you still make all the repayments. Their guarantee simply tops up your security so the lender treats you as having a larger deposit.
What that can mean for you:
• Buy sooner — you may not need to wait years to save a full deposit.
• Skip LMI — getting your effective deposit to 20% can remove Lenders Mortgage Insurance, often saving anywhere from $15,000 to $35,000+.
• Borrow up to the full purchase price in some cases, with a guarantee in place.
It's important to be clear-eyed about the guarantor's side too. They're responsible for the guaranteed portion if repayments aren't met, it can affect their own borrowing capacity, and they should always get independent legal advice before signing. The good news: a "limited guarantee" can cap their exposure to just the shortfall amount, and the guarantee can usually be released once your loan drops to 80% of the property value — through repayments or price growth.
A guarantor isn't right for every family, but for many it's the difference between buying now and buying years from now.
