What exactly is a family guarantee home loan?
A family guarantee loan lets your adult child buy a home using your property equity as additional security for their loan. Your home simply acts as backup security that reduces the lender’s risk, which eliminates the need for lenders mortgage insurance and allows smaller deposits.
Most lenders allow guarantees for deposit gaps up to 20% of the purchase price, meaning your child can buy with as little as a 5% deposit where they might otherwise need 20-25%. The exact structure depends on your equity position, your child’s income, and which lender assesses the application, which is exactly what we work through with families in a free consultation.

How do mortgage brokers help families set up guarantee loans in South East Melbourne?
Step 1: Talk to us
Get in touch and we’ll assess your family’s situation, your equity position, your child’s income and deposit, and which lenders offer the most suitable guarantee terms.
Step 2: Structure the guarantee amount
We calculate exactly how much guarantee is needed based on the purchase price and available deposit. Most families guarantee 15-20% of the purchase price, allowing their child to proceed with a 5-10% deposit.
Step 3: Compare lender policies
Different lenders have varying rules around guarantee amounts, release conditions, and ongoing requirements. We identify which lenders give your family the strongest terms and most flexible exit strategy.
Step 4: Coordinate legal documentation
Family guarantee loans require specific legal documentation to protect both parties. We coordinate with your solicitors to ensure the guarantee structure is properly documented before settlement.
Step 5: Process the application
We submit applications to pre-approved lenders and manage the approval process, keeping both generations informed throughout.
Step 6: Plan the guarantee release
We establish clear criteria for when the guarantee can be removed, typically when your child has paid down enough principal or the property has grown in value sufficiently to reach 80% loan-to-value ratio.
What mistakes do families commonly make with guarantee arrangements?
The biggest mistake is not getting independent legal advice before signing. Family guarantee loans create a legal relationship between your property and your child’s debt. If your child defaults, your property becomes liable for the shortfall. Every family should understand this risk clearly before proceeding.
Another common issue is not establishing clear exit criteria upfront. Families often arrange guarantees informally without documenting when and how the guarantee will be released. This creates problems later when your child wants to refinance or when you want to sell or downsize your own property. The release conditions should be written into the loan structure from day one.
How does a family guarantee affect your own borrowing capacity?
When you provide a family guarantee, lenders typically treat the guaranteed amount as a potential liability on your credit file. This can reduce your own borrowing capacity if you’re planning to refinance, upgrade, or access equity for other purposes.
Most lenders assess the guaranteed amount as a contingent liability at around 20-30% weighting, rather than 100%. The impact varies significantly between lenders; some are more conservative, others barely factor it in. If you’re planning your own property moves in the next few years, we assess how different lenders treat guarantee liabilities before recommending where to place your child’s loan.
Also worth noting: the APRA serviceability buffer currently sits at 3.0%, meaning lenders assess new borrowing at approximately 3% above the actual rate. With competitive variable rates from approximately 5.70% p.a., the assessment rate sits at around 9%, which factors into both your child’s capacity and your own contingent position.

Frequently Asked Questions
How much can my child borrow with a family guarantee home loan?
Your child’s borrowing capacity depends on their income, not the guarantee amount. The guarantee simply allows them to proceed with a smaller deposit and avoid LMI; it doesn’t increase what they can actually afford to repay.
Can I limit my family guarantee to a specific dollar amount?
Yes, most lenders allow you to cap your guarantee at a specific dollar figure rather than an unlimited amount. This limits your maximum exposure and makes the arrangement clearer for both parties.
What happens if my child can’t make repayments on their guarantee loan?
If your child defaults on their loan, the lender can pursue both the mortgaged property and your guaranteed amount to recover the debt. You would become liable for any shortfall up to your guarantee limit, which is why independent legal advice before signing is essential.
When can the family guarantee be removed from the home loan?
Most guarantees can be removed when your child’s loan reaches 80% loan-to-value ratio through repayments or property growth. Some lenders require a formal valuation and application process to release the guarantee.
Can a family guarantee be used for an investment property purchase?
Most lenders restrict family guarantees to owner-occupied purchases only. Investment property purchases typically require larger deposits and don’t qualify for guarantee arrangements with parents.
Should families use a mortgage broker or go directly to a bank for a guarantee loan?
A mortgage broker, every time. Family guarantee products vary significantly between lenders in terms of flexibility, release conditions, and impact on your own borrowing capacity. We compare 60+ lenders to find the structure that works best for your family’s specific situation.
Do both parents need to sign a family guarantee?
If your property is owned jointly, most lenders require both owners to sign the guarantee documentation. The guarantee affects the property title, so all registered owners must consent to the arrangement.
Your Next Steps
Family guarantee loans can be the difference between your child buying now versus waiting years to save a larger deposit, but the legal and financial implications affect your whole family’s position. The right lender choice determines not just the loan terms, but how flexible the exit strategy will be when it’s time to remove the guarantee.
The right lender for a family guarantee depends on your situation, and that’s a conversation worth having. Talk to the EverLend team or call 03 7036 3356, and we’ll compare your options across 60+ lenders at no cost to you.
