Guarantor loan

A guarantor home loan allows a family member (usually a parent) to use the equity in their own property as additional security for your loan. This reduces your effective Loan to Value Ratio (LVR) to 80% or below, which means you can avoid paying Lenders Mortgage Insurance (LMI) and buy a home with a low deposit or even no deposit at all. A family guarantee does not involve gifting cash. The guarantor simply pledges a limited portion of their property equity as security. They do not make repayments on your loan and are only liable for the guaranteed portion if you default.

Why choose Buyvest for your guarantor home loan

A family guarantee involves two parties, two properties, and complex lender policies. Here is what our mortgage broker team provides:

Lenders have very different rules for guarantor home loans. Some only accept parents as guarantors, while others accept siblings, grandparents, or de facto partners. Some require the guarantor property to be unencumbered (no existing mortgage), while others accept properties already mortgaged with the same lender. Some require genuine savings of 5%, while others accept a guarantor home loan with no deposit at all. Our mortgage broker team knows which lenders match your specific family situation.

LMI can cost $8,000 to $35,000 or more depending on your loan size and LVR. A family guarantee reduces your effective LVR to 80% or below, which means you avoid LMI entirely. This is one of the biggest financial benefits of a guarantor home loan. Our mortgage broker team calculates exactly how much guarantor equity is needed to bring your LVR under the 80% threshold and waive LMI. Read more about how LMI works.

A guarantor home loan affects two families. The guarantor needs to understand exactly what they are agreeing to: that their property is used as security, that they are liable for the guaranteed portion if you default, and that they need independent legal advice before signing. Our mortgage broker team sits down with both parties, explains the structure clearly, and ensures everyone is comfortable before proceeding.

Most modern guarantor home loans use a limited guarantee, meaning the guarantor is only responsible for a specific dollar amount or percentage (not the entire loan). The guarantee is typically capped at the amount needed to reduce your LVR to 80%. Our mortgage broker team structures the limited guarantee to minimise risk for the guarantor while giving you maximum borrowing power. We also plan the strategy to release the guarantor as quickly as possible.

Our mortgage broker service is completely free. The lender pays our commission when your guarantor home loan settles. You pay the same rate whether you go to the bank directly or through us. You get expert guidance, lender comparison, and family guarantee structuring at zero cost. Learn about our team.

A family guarantee is not meant to last forever. Most guarantors can be released once the borrower's loan balance falls below 80% of the property value (through repayments, property value growth, or a combination). Our mortgage broker team plans this exit strategy from the start, monitors your LVR, and initiates the guarantor release process when the time is right. We can also help you refinance at that point to secure a better rate.

How a guarantor home loan works

Understanding the structure of a family guarantee helps both borrower and guarantor make informed decisions:

A family guarantee (also called a family security guarantee or guarantor home loan) is a lending arrangement where a close family member offers part of their property equity as additional security for your loan. This reduces the lender's risk, lowers your effective LVR to 80% or below, and removes the need for LMI. The guarantor does not make repayments on your loan and does not give you cash. They simply provide their property as security for the guaranteed portion.

Read about LVR

Most lenders accept parents as guarantors. Some also accept siblings, grandparents, adult children, de facto partners, or other immediate family members. The guarantor must own residential property (either their own home or an investment property) with sufficient equity. All property owners on the title must agree to become guarantors. Some lenders require the guarantor property to be in Australia. Our mortgage broker team identifies which lenders accept your specific family arrangement.

Explore pathways to ownership

The guarantor needs enough equity to cover the gap between your deposit and 20% of your purchase price (the amount needed to bring your LVR to 80%). For example, if you are buying a $800,000 property with a 5% deposit ($40,000), the lender needs an additional $120,000 in security to reach 80% LVR. The guarantor property must have at least this amount in usable equity (property value minus existing mortgage, staying under 80% LVR on the guarantor property itself). Use our home equity calculator to estimate.

Read about deposit options

A limited guarantee caps the guarantor's liability to a specific dollar amount (typically the portion needed to reduce your LVR to 80%). The guarantor is not responsible for the full loan. This is the standard structure used by most lenders today and significantly limits the guarantor's risk. Our mortgage broker team always recommends a limited guarantee and structures it to minimise exposure for the guarantor while maximising your borrowing power.

Compare loan structures

A family guarantee and a gifted deposit are two different things. A gifted deposit involves a family member giving you cash toward the purchase (with a signed gift letter confirming it does not need to be repaid). A family guarantee uses property equity as security without transferring any cash. A gifted deposit only avoids LMI if it brings your total deposit above 20%. A family guarantee can avoid LMI even with a very low deposit or no deposit, because the additional security reduces your effective LVR.

Read about genuine savings

A guarantor can be released once your loan balance falls below 80% of your property value. This can happen through regular repayments reducing the balance, the property increasing in value, or both. Once the LVR drops below 80%, you (or your mortgage broker) apply to the lender for a guarantor release. The lender orders a new valuation, confirms the LVR is under 80%, and removes the guarantee from the title. Our mortgage broker team monitors your LVR and initiates the release as soon as it is achievable.

How a guarantor home loan works with Buyvest

1Free guarantor loan consultation

We meet with you (and your guarantor if available) to assess your borrowing power, calculate how much guarantor equity is needed, and discuss the family guarantee structure. We check your genuine savings, review both your financial position and the guarantor property equity, and compare guarantor home loan options across 35+ lenders to find the right fit.

2Application and independent legal advice

We submit your guarantor home loan application with all required documents for both borrower and guarantor. The lender values both properties. Your guarantor obtains independent legal advice (a legal requirement for most lenders) to confirm they understand the guarantee. Once approved, the lender issues loan documents for both parties.

3Settlement and guarantor release plan

We coordinate settlement between all parties. Your guarantor home loan settles with no LMI. From day one, we plan the guarantor release strategy: monitoring your LVR, tracking property value growth, and initiating the release application once your balance falls below 80% LVR. We can also help you refinance to a better rate at that point.

Frequently asked questions about guarantor home loans

Real answers to the questions borrowers and guarantors ask us:

A guarantor home loan is a lending arrangement where a family member uses the equity in their property as additional security for your loan. This reduces your effective LVR to 80% or below, allowing you to buy with a low deposit or no deposit and avoid paying Lenders Mortgage Insurance. The guarantor does not make repayments on your loan and is only liable for the guaranteed portion if you default.

LMI is charged when your LVR is above 80% (meaning your deposit is less than 20%). A family guarantee provides additional security from the guarantor property, effectively reducing your LVR to 80% or below in the lender's assessment. Because the combined security covers the risk, the lender does not require LMI. This can save you $8,000 to $35,000 or more depending on the loan amount. Read more about LMI.

Some lenders allow you to borrow up to 100% of the purchase price (plus costs such as stamp duty and legal fees) with a guarantor home loan. However, most lenders still require you to demonstrate some genuine savings (typically 5%) even with a family guarantee, to show you can manage your finances. Our mortgage broker team identifies which lenders accept no deposit guarantor home loans and which require minimum savings.

Most lenders accept parents as guarantors. Some also accept siblings, grandparents, adult children (over 18), de facto partners, and other immediate family members. All owners on the guarantor property title must agree to become guarantors. The guarantor must own residential property in Australia with sufficient equity. Our mortgage broker team knows which lenders accept your specific family relationship.

A limited guarantee caps the guarantor's liability to a specific dollar amount, typically the portion needed to reduce your LVR to 80%. The guarantor is not responsible for the entire loan amount. This is the standard structure used by most lenders today. It significantly reduces risk for the guarantor while still providing the security the lender needs to waive LMI and approve your guarantor home loan.

No. The guarantor does not make any repayments. You (the borrower) are fully responsible for all loan repayments. The guarantor is only called upon if you default on your loan and the lender cannot recover the debt from selling your property. With a limited guarantee, the guarantor is only liable for the guaranteed portion, not the full loan amount.

If you default and the lender sells your property but the sale does not cover the full debt, the lender can pursue the guarantor for the guaranteed portion. With a limited guarantee, this is capped at a specific amount. In extreme cases, the guarantor's property could be sold to satisfy the guarantee. This is why independent legal advice is required and why our mortgage broker team ensures both parties fully understand the arrangement.

Yes. Most lenders require the guarantor to obtain independent legal advice from a solicitor before signing the guarantee. This is a consumer protection measure ensuring the guarantor understands their obligations, the risks involved, and the circumstances under which they could be called upon to pay. The cost of independent legal advice is typically $200 to $500.

The guarantor needs enough usable equity to cover the gap between your deposit and 20% of the purchase price. Usable equity is the guarantor property value minus any existing mortgage, staying below 80% LVR on the guarantor property. For example, if the guarantor property is worth $1,000,000 with a $400,000 mortgage, the usable equity is $400,000 ($1M x 80% = $800K minus $400K). Our home equity calculator helps you estimate.

Some lenders require the guarantor property to be unencumbered (no mortgage), while others accept properties with an existing mortgage, provided there is sufficient equity. In some cases, the guarantor may need to refinance their mortgage to the same lender as your guarantor home loan. Our mortgage broker team identifies which lenders work with your guarantor's existing mortgage situation.

The Home Guarantee Scheme is a government program where the government acts as guarantor, allowing eligible first home buyers to purchase with a 5% deposit without LMI. A family guarantee is a private arrangement where a family member provides equity as security. The government scheme has eligibility criteria and property price caps. A family guarantee has no government restrictions on property price or income, but requires a willing family member with sufficient property equity.

A gifted deposit is cash given by a family member with a signed gift letter confirming it does not need to be repaid. A family guarantee uses property equity as security without any cash transfer. A gifted deposit only avoids LMI if it brings your total deposit above 20%. A family guarantee can avoid LMI even with a very small deposit because it provides additional property security. The two can sometimes be combined.

Some lenders allow guarantor home loans for investment property purchases, though policies vary. Certain lenders restrict family guarantees to owner-occupied purchases only. Some require the borrower to not own any other properties at the time of application. Our mortgage broker team identifies which lenders on our panel accept guarantor home loans for investment property and structures the loan accordingly.

Most lenders require you to demonstrate some genuine savings (typically 5% of the purchase price held for at least 3 months) even with a family guarantee. Genuine savings show the lender you can manage your finances. Some lenders are more flexible and may accept rent payments or other evidence of financial discipline. Our mortgage broker team finds lenders that match your savings position.

Your borrowing power is based on your income, expenses, and existing debts, not the guarantor's income. A family guarantee helps with security (reducing LVR) but does not increase your serviceability. The lender assesses whether you can afford the full loan repayments on your own, without relying on the guarantor's income. The guarantor's equity provides the security the lender needs, but you must demonstrate you can service the loan independently.

A guarantor can typically be released once your loan balance falls below 80% of your property value (the 80% LVR threshold). This can happen through regular repayments, extra repayments, or your property increasing in value. Depending on the property market and your repayment rate, this might take 2 to 5 years. You or your mortgage broker apply to the lender, a new valuation is obtained, and the guarantee is removed from the title.

Generally, no. While the family guarantee is active, the guarantor property has a security interest (caveat or second mortgage) registered against it. The guarantor cannot sell or refinance without either releasing the guarantee first or substituting alternative security. This is an important consideration for guarantors to understand before agreeing. Our mortgage broker team explains all implications clearly.

Yes. Guarantor home loans are one of the most common ways first home buyers enter the market. If your parents have sufficient property equity, a family guarantee allows you to buy sooner with a smaller deposit and avoid LMI. First home buyers may also combine a guarantor home loan with the First Home Owner Grant and stamp duty concessions.

Yes. Self-employed borrowers can access guarantor home loans, though additional documentation (typically 2 years of tax returns) is required. A family guarantee helps self-employed buyers overcome the deposit barrier while still needing to demonstrate serviceability from business income. Our mortgage broker team finds lenders that are flexible with self-employed guarantor home loan applicants.

The lender assesses the guarantor's ability to service the guaranteed portion if the borrower defaults. This includes reviewing the guarantor's income, employment stability, existing debts, credit history, and the equity in their property. Some lenders are more thorough than others. If the guarantor is retired and self-funded, lenders may accept superannuation income or investment income as evidence of ability to meet the guarantee.

Yes, provided there is enough usable equity after accounting for their existing mortgage. Some lenders require the guarantor to refinance their mortgage to the same lender as your guarantor home loan. Others accept a second mortgage behind the existing loan. The key factor is whether the combined LVR on the guarantor property (existing mortgage plus guarantee amount) stays below 80%. Our mortgage broker team assesses this during the initial consultation.

The main risk is that the guarantor's property is used as security. If the borrower defaults and the sale of the borrower's property does not cover the debt, the lender can pursue the guarantor for the guaranteed amount. In a worst case scenario, the guarantor's property could be sold. A limited guarantee caps this liability. The guarantor also cannot freely sell or refinance their property while the guarantee is active. Independent legal advice ensures the guarantor understands all risks.

No. The Home Guarantee Scheme is a government guarantee that replaces the need for a family guarantor. You use one or the other, not both. If you qualify for the government scheme, it may be preferable because it does not place any risk on a family member. If you do not qualify (or the property exceeds the price cap), a family guarantee is the alternative. Our mortgage broker team advises which option suits your situation.

Yes. Guarantor home loans involve two parties, two properties, and lender policies that vary significantly. A mortgage broker compares policies across 35+ lenders, identifies which lenders accept your family arrangement, structures the limited guarantee correctly, ensures the guarantor obtains independent legal advice, coordinates settlement, and plans the guarantor release strategy. The service costs $0 because the lender pays the broker's commission.
