Boosting Your Borrowing Power Through Guarantor Home Loans

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.

Your Guide to Guarantor Home Loans: Getting Into Your First Home Faster

Stuck in the rent cycle while trying to save a deposit? You’re not alone. At Ausfirst Lending Group, we help first home buyers break into the property market sooner with guarantor loans—even if you haven’t saved the full 20% deposit yet.

So, What Exactly Is a Guarantor Home Loan?

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:

  • Your guarantor doesn’t hand over money. Instead, they allow the lender to use part of their home’s equity as security alongside your new property.
  • It’s usually a family thing. Most lenders want a parent, grandparent, or sibling to guarantee your loan. Some accept other relatives depending on their policies.
  • You might not need a big deposit. Because your guarantor’s equity fills the gap, you could buy with just 5% down—or sometimes even nothing at all.
  • You’re still in the driver’s seat. You make all the repayments. But if things go wrong and you can’t pay, your guarantor becomes responsible for covering the guaranteed portion.

Why First Home Buyers Love This Option

Stop Waiting, Start Buying

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.

Skip Lender’s Mortgage Insurance (LMI)

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.

Borrow What You Actually Need

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.

Works Even With Limited Savings

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.

Your Guarantor Won’t Be Tied Up Forever

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.

But Let’s Talk About the Risks Too

Real talk: Guarantor loans aren’t without their downsides. Both you and your guarantor need to go in with eyes wide open.

Your Guarantor Is Taking On Real Risk

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.

It Affects Their Borrowing Power

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.

There’s a Credit Impact

The guarantee shows up on your guarantor’s credit file, which could affect future loan applications or credit cards they might want.

Family Dynamics Can Get Complicated

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.

Legal Hoops Are Required

Lenders will insist your guarantor gets independent legal and financial advice before committing. This protects everyone by making sure the decision is fully informed.

Who Can Actually Be Your Guarantor?

Lenders are pretty specific about who qualifies. Here’s what they typically look for:

  • Close family members. Parents are most common, but siblings and grandparents usually work too. Some lenders accept extended family or even ex-partners, though that varies.
  • They need to own property. Your guarantor must own a home in Australia with enough equity available to offer as security.
  • Financial stability matters. Lenders check your guarantor’s income, assets, debts, and credit history to make sure they could handle the responsibility if needed.
  • Age isn’t necessarily a dealbreaker. Older guarantors might face more questions about retirement plans, but it doesn’t automatically rule them out.
  • They have to genuinely agree. Your guarantor needs to sign formal documents and get legal advice—no one can be pressured into this.

What Lenders Want to See From You

Having a guarantor helps, but you still need to qualify on your own merits:

  • Stable income and employment. Lenders want to see you can afford the repayments with consistent income and a solid work history.
  • Some savings help. Even with a guarantor, many lenders like to see you’ve got a small deposit or genuine savings tucked away.
  • Clear loan purpose. Most guarantor loans are for first homes, but they can work for investment properties too. The lender will assess the property’s value and location.
  • The right property. Not every property qualifies. Lenders review the type, condition, and how easy it would be to sell if needed.
  • Everyone’s agreement. Your guarantor needs to be on board and meet the lender’s requirements.

Getting Your Guarantor Off the Hook

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.

  • Refinancing is typical. Most lenders require you to refinance internally to remove the guarantee. This includes a new valuation, credit check, and income review to confirm you can manage alone.
  • Expect some costs. There might be discharge fees, valuation costs, or admin charges—factor these in when planning the release.
  • Timing varies. How quickly you reach the equity threshold depends on property market conditions and how aggressively you pay down your loan.

Can You Refinance or Switch Later?

Absolutely. Refinancing a guarantor loan is common and often smart. Here’s why people do it:

  • Remove the guarantor. This is the main reason most people refinance—to release their guarantor once they’ve built enough equity.
  • Get better rates. Once your financial position improves, you might qualify for lower interest rates or more flexible loan features.
  • Adjust your loan structure. You can switch to a standard loan that better suits your long-term goals.
  • You’ll be reassessed. Just like your first application, you’ll need to pass serviceability checks and credit reviews. The property gets revalued too.
