How to Use a Guarantor to Buy a Home in Australia: A Complete Guide

Buying your first home in Australia can feel like an uphill battle, especially when saving for a 20% deposit seems impossible. But there’s a pathway that many first-home buyers overlook: using a guarantor. A guarantor home loan, often called a family guarantee, can help you enter the property market sooner, avoid Lenders Mortgage Insurance (LMI), and potentially secure a better interest rate. This guide explains everything you need to know—from how it works to the risks and step-by-step application process.


What Is a Guarantor Home Loan?

A guarantor home loan is a mortgage where a third party—usually a close family member like a parent—uses their own property or savings as security for your loan. This arrangement allows you to borrow up to 100% of the property’s purchase price without needing a full deposit. The guarantor’s asset acts as additional collateral, reducing the lender’s risk. In Australia, this is most commonly structured as a family pledge or family guarantee, where the guarantor provides a limited guarantee, typically up to 20% of the property value.

Unlike a standard loan, the guarantor doesn’t make repayments unless you default. Their liability is often capped, meaning they only guarantee a specific portion of the loan, not the entire amount. Once you’ve built enough equity or paid down the loan, the guarantee can be released, freeing the guarantor from their obligation.

Key Features

• Borrow up to 105%: Some lenders allow you to borrow more than the purchase price to cover stamp duty and other costs.
• No LMI: By using a guarantee, you can avoid LMI, which can save tens of thousands of dollars.
• Limited guarantee: The guarantor’s obligation is usually restricted to a set dollar amount, not the full loan.

Who Can Be a Guarantor?

Lenders have strict criteria for who can act as a guarantor. Typically, the guarantor must be a close relative with a strong credit history and sufficient equity in their own property. The most common guarantors are:

• Parents: The majority of family guarantees involve parents helping their adult children.
• Siblings: In some cases, brothers or sisters can act as guarantors, but this is less common.
• Other family members: Grandparents, aunts, or uncles may be accepted by certain lenders, but policies vary.

Benefits for the Borrower

Using a guarantor can be a game-changer for first-home buyers or those with limited savings. Here are the primary advantages:

1. Enter the Market Sooner

Saving a 20% deposit can take years, especially with rising property prices. In 2024, the median house price in Sydney exceeded $1.3 million, meaning a 20% deposit is over $260,000. A guarantor loan allows you to buy now with a minimal deposit, sometimes as low as 5% genuine savings.

2. Avoid Lenders Mortgage Insurance

LMI is a one-off premium that protects the lender if you default. On a $500,000 loan with a 10% deposit, LMI can cost around $12,000–$15,000. By using a guarantee, you can avoid this cost entirely, saving money that can go towards your home or other expenses.

3. Access Better Interest Rates

With a guarantor, you’re often viewed as a lower-risk borrower, which can qualify you for competitive interest rates. Some lenders offer the same rates as borrowers with a 20% deposit.

4. Consolidate Other Debts

In some cases, you can use a guarantor loan to consolidate high-interest debts like credit cards or personal loans, though this should be approached cautiously.

Risks and Considerations for the Guarantor

While a guarantor loan can be a generous act of support, it’s not without risks. Guarantors must fully understand what they’re signing up for.

Financial Liability

If you (the borrower) default on the loan, the lender can call on the guarantee. This means the guarantor may need to pay the guaranteed amount, which could force them to sell their property or use their savings. The guarantee is usually limited, but it’s still a significant commitment.

Impact on Borrowing Capacity

Being a guarantor reduces the guarantor’s own borrowing capacity. If they want to refinance, invest, or take out a new loan, lenders will consider the guarantee as a contingent liability. This can limit their financial flexibility.

Relationship Strain

Money and family can be a volatile mix. If the borrower struggles with repayments, it can create tension and strain relationships. Open communication and a clear agreement are essential.

Release of Guarantee

Most lenders allow the guarantee to be released once the borrower’s equity reaches a certain threshold (often 20% of the property value) or after a set period, typically 3–5 years. However, this isn’t automatic; the borrower must apply and meet the lender’s criteria.

Step-by-Step Process to Apply for a Guarantor Home Loan

Navigating a guarantor home loan involves several stages. Here’s a practical roadmap:

Step 1: Assess Your Financial Situation

Before approaching a guarantor, ensure you can afford the loan. Lenders will assess your income, expenses, and credit history. Use online calculators to estimate repayments and factor in rate rises. The Australian Prudential Regulation Authority (APRA) requires lenders to apply a 3% serviceability buffer, so your borrowing capacity may be lower than expected.

Step 2: Discuss with Potential Guarantor

Have an honest conversation about the risks and responsibilities. The guarantor should seek independent legal advice—this is a legal requirement in Australia. Together, decide on the guarantee amount and structure.

Step 3: Choose a Lender

Not all lenders offer guarantor loans, and policies vary. Compare features like:

• Maximum loan-to-value ratio (LVR) allowed
• Guarantee release conditions
• Interest rates and fees
• Eligibility criteria for guarantors

Some popular lenders in 2024 offering family guarantee loans include major banks and specialist lenders. A mortgage broker can help you find the best fit.

Step 4: Prepare Documentation

You’ll need:

• Proof of income (payslips, tax returns)
• Identification documents
• Details of the property you’re buying
• Guarantor’s financial documents (property title, mortgage statements, income proof)
• Signed guarantee agreement after legal advice

Step 5: Submit Application and Valuation

The lender will value both the property you’re buying and the guarantor’s security. If the valuations are satisfactory, the loan proceeds to approval.

Step 6: Settlement and Beyond

Once approved, the loan settles, and you become a homeowner. Keep track of your equity and loan balance. As soon as you meet the release conditions, apply to remove the guarantee to free your guarantor.

Alternatives to a Guarantor Home Loan

If a guarantor isn’t feasible, consider these options:

1. First Home Buyer Government Schemes

In 2024, the Australian Government offers several initiatives:

• First Home Guarantee (FHBG): Allows eligible buyers to purchase with a 5% deposit without LMI, with the government acting as guarantor.
• Family Home Guarantee: For single parents with a 2% deposit.
• Regional First Home Buyer Guarantee: For buyers in regional areas.

These schemes have caps on property prices and income thresholds.

2. Lenders Mortgage Insurance

If you have a deposit of at least 5–10%, you can pay LMI. While it adds to the cost, it allows you to buy without a guarantor. Some lenders capitalise LMI into the loan, so you don’t pay it upfront.

3. Gifted Deposit

Family members can gift funds towards your deposit. Lenders require a statutory declaration confirming the gift is non-repayable.

4. Shared Equity Schemes

Some state governments and private companies offer shared equity arrangements, where they contribute to the purchase price in exchange for a share of the property.

FAQ

1. Can a guarantor be removed from the loan later?

Yes. Most lenders allow the guarantee to be released once you have built enough equity (usually 20% of the property value) and can demonstrate that you can manage the loan independently. You may need to pay for a valuation and meet other conditions. It’s not automatic—you must apply to the lender.

2. What happens if the borrower defaults?

If you can’t make repayments, the lender will first try to recover the debt by selling your property. If there’s a shortfall, they may call on the guarantee. The guarantor is then liable up to the guaranteed amount. This is why it’s crucial to have a clear plan and insurance, such as income protection.

3. Is a guarantor home loan only for first-home buyers?

No. While common among first-home buyers, guarantor loans are available to anyone who meets the lender’s criteria, including investors or those refinancing. However, policies may differ, and some lenders restrict them to owner-occupied purchases.

4. How long does the guarantee last?

The guarantee typically lasts until you apply for a release, which can be after 3–5 years, depending on property value growth and your repayments. Some lenders have a minimum timeframe before you can request a release.

5. Can I use a guarantor if I have bad credit?

It’s unlikely. Lenders require the borrower to have a reasonable credit history. If you have defaults or bankruptcy, you may not qualify, even with a guarantor. In such cases, you might need to work on improving your credit score first.
