Guarantor home loans: Eligibility, risks and exit strategy
Introduction
Stepping into the property market is an incredible milestone, but meeting strict lending criteria can often feel like a significant hurdle. If your savings aren’t quite reaching the mark, a guarantor loan could be the key to opening those doors sooner than you thought possible.
By leveraging the equity of a supportive family member, you can bypass traditional deposit barriers and secure your future home today. In this blog post, we will break down exactly how this process works and whether it’s the right move for your journey.
Key takeaways
- Guarantor home loans allow buyers to purchase property using a guarantor’s equity.
- The loan is split into a main loan and a guaranteed portion.
- Using a guarantor usually often allows borrowers to avoid LMI.
- LMI savings can range from $15,000 to $35,000 or more.
- Guarantors must receive independent legal advice before signing.
- Guarantors can usually be released once the loan reaches 80% LVR.
What is a guarantor home loan?
Most people understand the concept of a "guarantee" in a casual sense; it’s a promise. In Australian real estate, it is a formal legal structure.
When you buy a home, the bank uses that property as collateral. If you borrow $600,000 to buy a $600,000 home (a 100% loan), the bank is nervous. If prices drop by even 5%, the debt exceeds the value of the house.
To mitigate this risk, banks prefer you to have a 20% deposit. A guarantor loan replaces that cash deposit with equity from another property (usually owned by your parents). Instead of you handing over $120,000 in cash, your parents offer $120,000 of the value in their home as a secondary backup for your loan.
Typically, the loan is split into two distinct portions to manage the risk:
- The main loan: This is the primary mortgage, secured by the property you are buying.
- The guaranteed portion: This is a smaller segment of the total debt, secured by a specific portion of the guarantor’s property.
Types of guarantor support
In Australia, guarantor arrangements are generally structured in two ways, depending on how the guarantor helps strengthen your home loan application.
1. Security guarantee (equity support)
This is the most common form of guarantor support. It is used when you can afford the loan repayments but do not have enough savings for a full deposit.
In this arrangement, a family member allows the lender to use a portion of the equity in their property as additional security for your loan. This reduces the lender’s risk and may allow you to borrow up to the full purchase price while avoiding Lenders Mortgage Insurance.
The guarantor does not provide cash. They sign a legal agreement that allows the lender to claim the guaranteed portion of their property only if the loan goes into default.
2. Servicing guarantee (income support)
Some lenders allow a guarantor to strengthen your application by supporting servicing. This may help if your income alone does not meet the lender’s affordability requirements.
In this case, the lender may consider the guarantor’s financial position when assessing the loan. Policies vary between lenders, and this type of support is less common than security guarantees.
Guarantor Home Loans vs First Home Guarantee
Is a guarantor loan better than the Government's First Home Guarantee (FHG)? Here is how they stack up:
| Feature | Guarantor Loan | First Home Guarantee (FHG) |
|---|---|---|
| Deposit required | 0%–5% | 5% minimum (2% for eligible single parents under Family Home Guarantee) |
| Lenders mortgage insurance | Usually $0 (guarantor covers risk) | $0 (government guarantee replaces LMI) |
| Income caps | None | Removed (No longer applies) |
| Property price caps | None (lender policy applies) | Still apply and vary by region (e.g. Sydney cap higher than regional areas) |
| Place limits | Unlimited | Limited places released each financial year |
| Family involvement | High – guarantor provides equity and takes legal risk | None – government provides guarantee |
| Interest rates | Standard market rates | Standard market rates (often competitive) |
The step-by-step process to secure a guarantor home loan
Here is the comprehensive breakdown of how the process works in the current Australian market.
1. Check eligibility and financial readiness
Before applying, the lender must make sure the loan can be repaid. This is where the two types of guarantor loans differ.
- Standard rule (security guarantee): Most lenders require you, the borrower, to prove you can afford the full loan repayments on your own. They review your income and expenses and test repayments at a rate about 3 percent higher than the current interest rate to ensure you can manage if rates rise.
- Servicing guarantor (limited situations): A small number of lenders may allow a servicing guarantor. In this case, if your income alone is not enough, the guarantor’s income may be considered to show the loan can be repaid. This is sometimes used for students or medical interns who are expected to earn more in the future.
- Common requirements: For both types of guarantees, you usually need a good credit history. The guarantor is typically an immediate family member and must meet the lender’s age and financial criteria.
2. Calculate the guarantee amount
Once the lender confirms the loan is affordable, they look at the security being provided.
- Limited guarantee: Instead of being responsible for the entire loan, the guarantor only guarantees a limited portion, often around 20 percent of the property value.
- The goal: This pledged equity acts like your deposit. It reduces your Loan to Value Ratio to 80 percent or less, which usually helps you avoid paying Lenders Mortgage Insurance.
- No cash needed: The guarantor does not give you money. They allow the lender to place a limited charge or small mortgage over part of their property as security.
3. Dual property valuations
The lender will order professional valuations for:
- The home you are buying.
- The guarantor’s existing property. Lenders generally require that the guarantor's total debt (their own mortgage + your guarantee) does not exceed 80% of their property's value.
Note: The guarantor must typically maintain at least 20% equity in their own home after the new guarantee is registered to ensure they aren't "over-leveraged."
4. Mandatory Independent Legal Advice (ILA)
Under the Australian Banking Code of Practice, a guarantee cannot be signed without formal oversight.
- The Solicitor: The guarantor must meet with an independent solicitor (not the borrower's lawyer) to discuss the risks.
- The Certificate: The solicitor must sign a Certificate of Independent Legal Advice, confirming the guarantor understands they are legally liable for the portion of the debt they have secured.
5. Approval & digital settlement (PEXA)
Once the valuations and legal checks are cleared, the loan moves to formal approval.
- Loan contracts: Both parties sign the mortgage documents (often via digital signing platforms).
- Settlement: Handled via PEXA (Australia’s digital property exchange). The bank registers a first mortgage on your new home and a "Limited Guarantee" (often a second mortgage or caveat) on the guarantor's title.
6. The exit strategy (Releasing the Guarantor)
A guarantor is not meant to stay on your loan forever. The goal is to remove them once your loan is strong enough to stand on its own. In most cases, you can apply for a guarantor release when your loan reaches 80% LVR and you can afford the repayments independently.
This point is usually reached through a combination of factors:
- Your property increasing in value over time
- Your loan balance reducing as you make repayment
- Refinancing to a new lender once you have at least 20% equity

Why do borrowers choose a guarantor loan?
Choosing a guarantor loan is often a strategic move to overcome the financial barriers that keep many buyers in the rental cycle for longer than necessary. By leveraging the strength of a family member's assets, you can unlock several key financial benefits that aren't available through traditional savings alone.
- Eliminate Lenders Mortgage Insurance (LMI): LMI is one of the most disliked costs in Australian real estate. It is a massive premium, often between $15,000 and $35,000, that you pay to protect the bank if you default. By using a guarantor to bring your Loan-to-Value Ratio (LVR) down to 80%, you effectively delete this cost. That is money that stays in your pocket or goes directly toward your mortgage principal.
- Reduce buying time: The "cost of waiting" is real. If property prices rise by 5% in a year, an $800,000 home becomes $840,000. If you are saving $40,000 a year, you are essentially standing still. A guarantor loan allows you to buy at today’s prices rather than chasing a market that is moving faster than you can save.
- Maximise borrowing capacity: Because the lender has additional security, they may allow you to borrow a higher percentage of the property value. This can reduce the amount of cash you need upfront and may help cover purchase costs such as stamp duty and legal fees, depending on the lender’s policy.
Who can be a guarantor? (The "Family" Rule)
Lenders are strict about who can provide a guarantee because they want to ensure the guarantor has a "natural love and affection" for the borrower. This reduces the likelihood of legal disputes later.
| Relationship Type | Status | Notes |
|---|---|---|
| Parents | Widely accepted | The most common type of guarantee. |
| Grandparents | Case-by-case | Some lenders allow it; others see it as higher risk. |
| Spouse | Accepted | Common if one partner has much higher assets than the other. |
| Friends/Uncles/Aunts | Rarely accepted | Usually requires a "specialty" or non-conforming lender. |
Requirements for the guarantor’s property:
- Must be located in Australia.
- Must be a residential property (commercial property is rarely accepted).
- Must have sufficient equity (Value - Existing Mortgage = Equity)
What are the risks of a guarantor home loan?
While guarantor loans help borrowers, they are not without risks. Here are a few critical factors that both parties must consider before entering into such an agreement. At ZedPlus, we believe in providing a complete picture so that families can make informed, secure decisions.
For the guarantor:
If the borrower stops making payments, the bank will first attempt to sell the primary property. If the sale of that home does not cover the total debt, the bank can turn to the guarantor to pay the remaining guaranteed amount. If the guarantor cannot pay that amount in cash, the bank has the legal right to force the sale of the guarantor’s property to recover the funds.
For the borrower:
Financial stress is a leading cause of family friction. If you fall behind on payments, you aren't just affecting your own credit score: you are potentially jeopardising your parents' retirement security and their most valuable asset. This creates a psychological responsibility that every borrower must be prepared to manage throughout the life of the guarantee.
Impact on future borrowing:
Being a guarantor is a contingent liability. This means that if the guarantor wants to take out a loan for themselves later, perhaps for a new car or a renovation, the bank will factor in the guaranteed amount as a potential debt. This could significantly reduce the guarantor's own borrowing power.

Is a guarantor loan right for you? A quick checklist
What happens if a guarantor wants to sell their property?
A common worry is: "What if my parents need to downsize while I'm still using their equity?" If the guarantor needs to sell their property before you have released them, you generally have two options:.
- Security swap: The guarantee can be moved to the new property they buy (provided there is enough equity).
- Cash security: A portion of their sale proceeds (equal to the guarantee amount) can be held in a locked term deposit with the bank until you reach 80% equity.
What if you miss repayments on a guarantor loan?
The bank's goal is always to get the debt paid, but they follow a specific order of operations:
- Primary sale: The bank will first sell your property to cover the loan.
- The shortfall: Only if your home sale doesn't cover the full debt will they look to the guarantor for the specific "guaranteed portion."
- Guarantor's responsibility: The guarantor can pay this shortfall in cash or, as a last resort, the bank can seek to sell their property to recover the fund.
Guarantor loans FAQs
1. Does my guarantor need to hand over cash?
No. This is a "paper guarantee." Your guarantor provides a legal charge over their property equity. No money moves between bank accounts unless there is a default later.
2. Can I use a guarantor if I’m buying with a partner?
Absolutely. Couples frequently use one set of parents as a guarantor. Note that both partners in the relationship are usually "jointly and severally" liable for the debt.
3. Does the "First Home Guarantee" (Gov Scheme) work with a guarantor loan?
Usually, no. You generally pick one or the other. The Government scheme allows a 5% deposit with no LMI, but it has strict price caps. A guarantor loan has no price caps, allowing you to buy a better property in a better suburb if your income supports it.
4. Can I buy a "Fixer-Upper" or do major renovations with a guarantor?
Yes, but with a catch. The bank values the property "as is." If you gut the kitchen and the value drops during the renovation, your LVR increases, and your parents are "stuck" as guarantors for longer.
5. What is the difference between a "Security Guarantee" and a "Servicing Guarantee"?
Beyond your mortgage repayments, you should allow for:
- Security Guarantee: Your parents provide their house as backup. (Standard and recommended).
- Servicing Guarantee: Your parents provide their income to help you qualify. (Rare and risky). Most major lenders have moved away from servicing guarantees because they prefer the borrower to be independently capable of making payments.
These costs are ongoing but manageable when planned for correctly from the outset.
6. Will my parents pay Capital Gains Tax (CGT) if they act as a guarantor?
In most standard guarantor home loan structures, your parents are not added to the property title and do not receive any ownership interest in the home. In this situation, simply acting as a guarantor is generally not a Capital Gains Tax (CGT) event, because they are not disposing of or transferring any ownership interest.
However, things can change if a parent is added to the property title as a co-owner or if part of their existing property ownership is transferred. Adding someone to the title can potentially trigger a CGT event on the portion transferred, depending on the circumstances. It may also affect eligibility for the main residence exemption, land tax thresholds, and could create stamp duty implications, which vary by state.
Because tax outcomes depend on individual circumstances and state legislation, it is important to seek independent tax advice before changing ownership structures or adding a family member to a property title.
7. What if the market crashes?
In a market crash, your property may fall into negative equity, where the debt exceeds the home's value. This "locks" your parents in as guarantors; since your Loan-to-Value Ratio (LVR) remains above 80%, the bank will refuse to release them. You cannot refinance to a better rate, and if forced to sell, your parents must legally pay any financial shortfall from their own assets.
