Many Gold Coast families are discovering that a family guarantee loan can help their adult children buy their first home without parents needing to gift a lump sum. Whether your child is looking at established homes or new builds, using your property’s equity as additional security can eliminate the need for lenders mortgage insurance and reduce the deposit requirement significantly.
With Gold Coast house prices sitting around the $1.35M LGA median and many first home buyers needing to compete in suburbs like Robina – Varsity Lakes or Nerang, a family guarantee can be the difference between buying now and waiting years to save a larger deposit. The structure lets parents help without affecting their own cash flow or borrowing capacity for other purposes.
Mortgage Innovations helps Gold Coast families structure family guarantee loans across our panel of 60+ lenders, completely free of charge.
Here’s what you need to know about how family guarantees work, what lenders assess, and how to protect both generations in the arrangement.
Key takeaways
- Parents provide equity as security, not cash, so their savings stay intact.
- A family guarantee can eliminate LMI on a 5% deposit purchase.
- The guarantee is released once the loan drops to 80% of the property value.
How do family guarantee loans reduce deposit requirements?
Your adult child typically needs just 5% deposit when you provide a family guarantee, rather than the standard 20% required to avoid lenders mortgage insurance. You use your property as additional security for a portion of their loan, usually 10-20% of their purchase price, which replaces the need for LMI and lets them enter the market sooner.
For example, on a $700,000 Gold Coast purchase, your child would need $35,000 (5%) plus buying costs, rather than $140,000 (20%). You guarantee approximately $70,000-$140,000 using your property’s equity, but you don’t provide any cash upfront.
How does a family guarantee loan work on the Gold Coast?
A family guarantee uses your property’s equity as security for part of your child’s home loan, eliminating the need for lenders mortgage insurance. Your child still takes out their own loan and makes all repayments – you’re providing security, not ongoing financial support. The guarantee typically covers 10-20% of the purchase price, depending on your equity position and their deposit amount.

How do mortgage brokers help families structure guarantee loans on the Gold Coast?
Step 1: Talk to us
Get in touch and we’ll assess whether a family guarantee suits your family’s situation or if other first home buyer schemes provide a better outcome.
Step 2: Review both properties and incomes
We assess your property’s equity position, your child’s borrowing capacity, and identify lenders who offer competitive family guarantee products.
Step 3: Structure the guarantee amount
We calculate the minimum guarantee required to eliminate LMI and determine the optimal loan structure across our panel of 60+ lenders.
Step 4: Prepare applications for both parties
We coordinate applications, valuations, and documentation for both the primary borrower and the guarantor to streamline the approval process.
Step 5: Manage settlement and registration
We work with your solicitors to ensure both properties are correctly secured and all legal documentation is properly executed.
Step 6: Plan the guarantee exit strategy
We discuss timeframes for removing the guarantee once your child builds sufficient equity, typically through property growth or additional repayments.
What mistakes do families make with guarantee loans?
The biggest mistake families make is not understanding the exit strategy before they start. Your property remains on the loan until your child refinances or pays down enough principal to remove the guarantee – this can take 2-5 years depending on property growth and repayment patterns. Without a clear timeline, families can feel trapped in the arrangement longer than expected.
The second common error is not protecting the guarantor’s position with proper legal advice. If your child defaults, you’re liable for the guaranteed portion, and the lender can pursue your property. Independent legal advice is typically required by lenders, but many families underestimate the importance of understanding their full liability before signing.
What equity do parents need to provide a family guarantee?
Most lenders require guarantor parents to retain at least 20% equity in their own property after providing the guarantee. If your home is worth $1,000,000 with a $200,000 mortgage, you have $800,000 equity – you could guarantee up to $600,000 while maintaining your 20% buffer.
Lenders also assess your income and expenses to ensure you can service both your existing loan and the guaranteed portion if required. Your age matters too – some lenders restrict guarantees for parents approaching retirement, while others require exit strategies before you turn 65-70.

Frequently Asked Questions
Can my child use a family guarantee with other first home buyer schemes?
Not with the First Home Guarantee – you choose a family guarantee or the government 5% scheme, but not both. The QLD first home transfer duty concessions and the $30,000 First Home Owner Grant can be used alongside a family guarantee.
What happens if my child can’t make repayments?
You become liable for the guaranteed portion of the loan, and the lender can pursue your property to recover that amount. This is why lenders require independent legal advice before you sign.
How long does the family guarantee last?
Until your child refinances or pays down enough principal to remove it – typically 2-5 years. Most families plan to exit when the loan balance drops to 80% of the property value.
Does providing a family guarantee affect my own borrowing capacity?
Yes – lenders treat the guaranteed amount as if it’s your own debt when assessing applications for new credit. This can reduce your borrowing capacity for other purposes.
Can I guarantee loans for multiple children?
Potentially, but each guarantee reduces your available equity and borrowing capacity for subsequent guarantees. Most families can only guarantee for one child at a time unless they have substantial equity.
Should I use a family guarantee or go directly to my bank?
A mortgage broker, every time. Family guarantee policies vary significantly between lenders – some offer more flexible exit conditions, others have different equity requirements. We compare the full market to find the structure that protects both generations.
What if property values fall after we set up a family guarantee?
You remain liable for the guaranteed amount regardless of property value movements. This is why exit planning and choosing the right guarantee amount upfront is crucial to your family’s financial security.
Your Next Steps
Getting a family guarantee structure right protects both generations and sets your child up for long-term financial success. The difference between lenders can affect your guarantee amount, exit options, and overall family risk – which is exactly what a broker comparison is designed to find for your situation.
