How to Use a Guarantor to Buy Property in Australia with No Deposit
Buying your first home in Australia can feel like an uphill battle, especially when you’re faced with the daunting task of saving a 20% deposit. With property prices in cities like Sydney, Melbourne, and Brisbane remaining high, many first home buyers are turning to alternative pathways to enter the market sooner. One of the most effective strategies is using a guarantor loan, which allows you to purchase a property with little to no deposit. In this comprehensive guide, we’ll walk you through everything you need to know about using a guarantor to buy property in Australia, including how it works, eligibility criteria, risks, and a step-by-step application process.

What Is a Guarantor Home Loan?
A guarantor home loan is a type of mortgage where a family member (usually a parent) uses the equity in their own property as security for your loan. This arrangement allows you to borrow up to 100% of the purchase price (and sometimes more to cover costs like stamp duty) without needing a cash deposit. The guarantor’s property acts as additional security, reducing the lender’s risk and enabling you to avoid Lenders Mortgage Insurance (LMI), which can save you thousands of dollars.
In Australia, guarantor loans are particularly popular among first home buyers who have a stable income but lack a sufficient deposit. According to the Australian Bureau of Statistics, the average first home buyer deposit in 2023 was around $120,000 — a sum that can take years to save. With a guarantor, you can bypass this hurdle and get into your own home much faster.
How Does a Guarantor Loan Work?
Here’s a simplified breakdown:
- You find a property you want to buy and apply for a home loan.
- Your guarantor (e.g., a parent) offers their property as additional security.
- The lender assesses both your financial situation and the guarantor’s property equity.
- If approved, you can borrow up to 100% of the property value (plus costs).
- The guarantor’s liability is usually limited to a specific amount (e.g., 20% of your loan), not the entire loan.
- Once you’ve built enough equity in your home or paid down the loan, the guarantor can be released.

Benefits of Using a Guarantor
Using a guarantor offers several compelling advantages for first home buyers:
- No Deposit Required: The most obvious benefit is entering the property market without saving a large deposit. This can save years of waiting and allow you to buy when prices are right.
- Avoid Lenders Mortgage Insurance (LMI): LMI can cost tens of thousands of dollars. By providing additional security, you often avoid this expense entirely.
- Potentially Lower Interest Rates: Some lenders offer better rates on guarantor loans because the risk is reduced.
- Access to Better Loan Features: You may qualify for loans with offset accounts, redraw facilities, or lower fees that would otherwise require a larger deposit.
- Sooner Market Entry: With property values historically rising over time, getting in earlier can mean significant capital gains.
According to a 2023 report by CoreLogic, Australian home values increased by 8.1% over the year, underscoring the opportunity cost of delaying a purchase.
Eligibility Requirements for Borrowers and Guarantors
Not everyone can be a guarantor, and borrowers must meet certain criteria. Here’s what lenders typically require:
For the Borrower
- Age: Usually 18 years or older.
- Income: Stable employment with sufficient income to service the loan. Lenders will assess your ability to repay the entire loan amount.
- Credit History: A good credit score and clean credit report are essential.
- Genuine Savings: While you may not need a cash deposit, some lenders want to see evidence of genuine savings (e.g., 5% of the purchase price) to demonstrate financial discipline. However, many guarantor loans waive this requirement.
- Citizenship/Residency: Typically Australian citizens or permanent residents. Temporary residents may face restrictions.
For the Guarantor
- Relationship: Usually an immediate family member (parent, sibling, or sometimes a grandparent). Some lenders accept other relatives or even friends, but family is most common.
- Property Ownership: The guarantor must own a property with sufficient equity. Most lenders require the property to be in Australia and have an unencumbered value that covers the guarantee amount.
- Income: Guarantors must demonstrate they can cover their own debts and the potential liability if you default. Retirees on a pension may be accepted if they have significant equity.
- Age: Some lenders impose age limits (e.g., under 65 or 70), but this varies.
- Independent Legal Advice: Guarantors are legally required to seek independent legal advice before signing, ensuring they understand the risks.
Risks and Considerations
While guarantor loans are powerful tools, they come with significant risks that both parties must understand.
For the Borrower
- Debt Responsibility: You are borrowing 100% of the property value, which means higher monthly repayments than if you had a deposit. Ensure your budget can handle potential interest rate rises.
- Relationship Strain: Mixing family and finances can lead to tension, especially if you struggle to make repayments.
- Limited Options: Not all lenders offer guarantor loans, and those that do may have stricter terms.
For the Guarantor
- Loss of Property: If you default on the loan and the sale of your property doesn’t cover the debt, the lender can seize the guarantor’s property to recover the guaranteed amount. This is the most severe risk.
- Impact on Borrowing Capacity: Being a guarantor reduces the guarantor’s own ability to borrow, as the guarantee is considered a contingent liability.
- Difficulty Exiting: The guarantor can only be released once you’ve built sufficient equity or reduced the loan balance. This could take several years.
It’s crucial for guarantors to fully understand these risks. The Australian Securities and Investments Commission (ASIC) provides a guide on guarantor loans that we recommend reading here.

Step-by-Step Application Process
Ready to take the plunge? Here’s a detailed walkthrough of how to secure a guarantor home loan.
Step 1: Assess Your Financial Situation
Before approaching a lender, calculate your borrowing capacity. Use online calculators to estimate how much you can afford based on your income, expenses, and current interest rates. Factor in additional costs like stamp duty, legal fees, and moving expenses.
Step 2: Discuss with Potential Guarantors
Have an open and honest conversation with your family member about their willingness and ability to act as a guarantor. Explain the risks and suggest they seek independent legal and financial advice. This is not just a formality — it’s a critical step to protect your relationship.
Step 3: Research Lenders and Loan Products
Not all lenders offer guarantor loans, and terms vary widely. Compare interest rates, fees, loan features, and the maximum LVR (loan-to-value ratio) allowed. Some popular lenders in Australia for guarantor loans include major banks like Commonwealth Bank, Westpac, and NAB, as well as smaller institutions. Look for loans that allow a limited guarantee (e.g., secured only up to 20% of the property value) to minimize the guarantor’s exposure.
Step 4: Get Pre-Approval
Once you’ve chosen a lender, apply for pre-approval. You’ll need to provide:
- Proof of identity (passport, driver’s license)
- Recent payslips and employment details
- Bank statements showing savings and expenses
- Details of any existing debts (credit cards, personal loans)
- The guarantor’s property details and consent
Pre-approval gives you a clear budget and shows real estate agents you’re a serious buyer.
Step 5: Find Your Property and Make an Offer
With pre-approval in hand, start house hunting. When you find the right property, make an offer subject to finance. Your lender will then conduct a valuation of the property and the guarantor’s property.
Step 6: Formal Loan Application
Submit the full application with the signed contract of sale. The lender will assess everything in detail, including the guarantor’s financial position. Both parties will need to sign the loan documents, and the guarantor must provide a certificate of independent legal advice.
Step 7: Settlement
Once approved, the loan proceeds to settlement. The lender will disburse the funds to the seller, and you become a homeowner! Remember, the guarantor’s property remains tied to your loan until you apply for a release.
Step 8: Plan for Guarantor Release
As you pay down your loan and your property increases in value, aim to release your guarantor as soon as possible. Most lenders allow a release when your LVR drops to 80% or less. You’ll need a valuation to confirm, and there may be a small fee.
Common Questions About Guarantor Loans

FAQ
Q: Can I use a guarantor if I have a poor credit history? A: It’s possible but more difficult. Lenders will still assess your creditworthiness. A guarantor with strong finances can help, but if your credit issues are severe (e.g., defaults, bankruptcy), you may be declined. Speak with a mortgage broker who specializes in bad credit scenarios.
Q: How long does the guarantor stay on the loan? A: Typically 2–5 years, but it depends on how quickly you build equity. If your property value rises or you make extra repayments, you can request a release earlier. Some lenders require a minimum period before considering release.
Q: What happens if the guarantor dies or wants to sell their property? A: If the guarantor dies, the guarantee may become payable from their estate, but this depends on the loan terms. If they want to sell, you’ll need to either release them (if you have enough equity) or find a replacement guarantor. Otherwise, the sale proceeds may be used to cover the guarantee.
Q: Can I use a guarantor for an investment property? A: Yes, some lenders allow guarantor loans for investment purchases, but it’s less common. The guarantor must still meet all criteria, and the risks are higher for both parties. First home buyers typically use this for owner-occupied properties.
Real-World Example
Consider Sarah, a 28-year-old teacher in Melbourne. She earns $85,000 a year and has saved $15,000, but the apartment she wants costs $600,000. Without a guarantor, she’d need a $120,000 deposit plus LMI, which would take her another 5 years to save. Her parents own their home outright, valued at $1.2 million. They agree to guarantee 20% of her loan ($120,000). Sarah borrows the full $600,000, avoids LMI (saving ~$20,000), and buys her apartment. She plans to make extra repayments and release her parents in 3 years.

Alternatives to Guarantor Loans
If a guarantor isn’t an option, consider these alternatives:
- First Home Owner Grant (FHOG): A one-off payment from state governments to help with purchase costs. Check your state’s rules, as amounts and eligibility vary.
- First Home Loan Deposit Scheme (FHLDS): The federal government guarantees up to 15% of the loan, allowing you to buy with a 5% deposit without LMI. Limited spots are available each year.
- Family Pledge Loans: Some lenders offer loans where family members can provide a term deposit as security instead of property.
- Saving a Larger Deposit: While slower, saving 10–20% gives you more lender options and lower risk.

Tips for a Smooth Guarantor Loan Experience
- Communicate Openly: Keep your guarantor updated on your financial situation and loan progress.
- Get Professional Advice: Both parties should consult a mortgage broker, solicitor, and financial advisor.
- Budget for Rate Rises: Use a repayment calculator with a buffer of 2–3% above current rates to ensure you can handle increases.
- Insure Your Income: Consider income protection insurance to cover repayments if you’re unable to work.
- Plan an Exit Strategy: From day one, know how and when you’ll release the guarantor.
Market Trends and Data (2023–2026)
As of early 2025, the Australian property market continues to evolve. The Reserve Bank of Australia (RBA) has kept the cash rate at 4.35% since late 2023, with potential cuts expected in 2025. This has stabilized borrowing costs. According to CoreLogic’s January 2025 Home Value Index, national dwelling values rose 0.4% in January, with Sydney up 0.3% and Brisbane up 0.5%. For first home buyers, using a guarantor remains a strategic move to capitalize on moderate price growth while avoiding high deposit hurdles.
| City | Median House Price (Jan 2025) | 5% Deposit Needed | 20% Deposit Needed |
|---|---|---|---|
| Sydney | $1,120,000 | $56,000 | $224,000 |
| Melbourne | $780,000 | $39,000 | $156,000 |
| Brisbane | $720,000 | $36,000 | $144,000 |
| Adelaide | $650,000 | $32,500 | $130,000 |
| Perth | $620,000 | $31,000 | $124,000 |

Conclusion
Using a guarantor to buy property in Australia with no deposit is a viable and increasingly popular strategy for first home buyers. It allows you to overcome the deposit barrier, avoid LMI, and enter the market years earlier than you could on your own. However, it’s not without risks — both financial and relational. Thorough research, open communication, and professional advice are essential to make this arrangement work for everyone involved.
If you’re ready to explore your options, start by talking to a mortgage broker who can compare guarantor loans from multiple lenders. With the right support, you could be holding the keys to your first home sooner than you think.
