Family Guarantee Home Loans on the Northern Beaches, The 2026 Guide
Family guarantee loans are helping Northern Beaches families bridge the gap between property prices and what their adult children can afford on their own. Whether your child is looking at units in Dee Why- Balgowlah or houses in Frenchs Forest, using family property as additional security can eliminate the need for lenders mortgage insurance and reduce deposit requirements significantly.
A family guarantee allows parents or other family members to use the equity in their own property as security for their child's home loan. The arrangement means your child can buy with as little as 5% deposit while avoiding LMI costs that would otherwise range from approximately $21,000 to over $40,000 on Northern Beaches property purchases.
Mortgage Brokers Northern Beaches helps families across the Northern Beaches structure family guarantee arrangements with lenders who offer competitive terms and clear exit strategies, completely free of charge.
Here's what you need to know about family guarantee loans before committing family property as security.
Key takeaways
- A family guarantee lets your child buy with 5% deposit and no LMI costs.
- Your property is security for their loan until the guarantee is removed.
- Most guarantees are released within 2-5 years once sufficient equity is built.
How does a family guarantee loan work on the Northern Beaches?
A family guarantee loan uses two properties as security for one loan. Your child becomes the borrower and owns the new property, while your property acts as additional security for their loan. The lender can claim against both properties if repayments stop, but your child makes all repayments and holds legal ownership of their home.
Most lenders allow parents to guarantee up to 20% of the purchase price, which typically covers the deposit shortfall and LMI costs. Your property needs sufficient equity, usually at least 20% available equity after accounting for any existing mortgage.
What are the main benefits of using a family guarantee?
Eliminating lenders mortgage insurance is the primary advantage, and it lets your child enter the market sooner rather than spending years saving a larger deposit. On a $1,200,000 unit purchase, LMI with a 5% deposit would cost approximately $50,000. A family guarantee removes that cost entirely and allows your child to buy now rather than waiting while property prices continue moving.
What government schemes work alongside family guarantees?
Family guarantee loans can be used alongside several first home buyer schemes available to Northern Beaches purchasers:
- › First Home Guarantee: your child can access the 5% deposit, no LMI government scheme if the property is under $1,500,000, though this overlaps with the family guarantee benefit of avoiding LMI.
- › NSW First Home Owner Grant:$10,000 for new homes under $600,000, though this price threshold is effectively unavailable on the Northern Beaches given local property values.
- › Help to Buy shared equity: up to 30% government contribution on existing homes for eligible first home buyers. Income caps apply: $103,000 for singles and $165,000 for joint applicants. The Sydney price cap is $1,300,000, which is lower than the First Home Guarantee's $1,500,000 cap, so fewer Northern Beaches properties qualify. A family guarantee and Help to Buy cannot be combined on the same loan.

How do mortgage brokers help families set up guarantee loans on the Northern Beaches?
Step 1: Talk to us
Get in touch and we'll assess your family's situation, review the equity available in your property, and identify which lenders offer the most suitable family guarantee terms for your circumstances.
Step 2: Property valuation and equity assessment
We coordinate a valuation of your property to confirm available equity, then calculate how much guarantee you can comfortably provide without over-committing your own property as security.
Step 3: Compare lender policies
We compare family guarantee terms across our 60+ lender panel, focusing on exit conditions, guarantee limits, and ongoing requirements that affect both you and your child.
Step 4: Structure the arrangement
We work with your child to structure their first home loan application alongside the guarantee documents, ensuring both parts of the arrangement meet lender requirements.
Step 5: Legal documentation
We coordinate with solicitors to ensure all guarantee documents are properly prepared and both parties understand their obligations before settlement proceeds.
Step 6: Plan the exit strategy
We discuss how and when the guarantee will be removed, typically after 2-5 years when your child has built sufficient equity to refinance without family support.
What are the main risks families should consider?
Your property becomes security for someone else's debt. If your child cannot make repayments, the lender can force the sale of your property to recover their loss. Most family guarantee arrangements include both properties as security until the guarantee is removed.
Your borrowing capacity will also be affected while the guarantee remains active. Lenders treat the guaranteed amount as your own debt when assessing any future loan applications, which can limit your ability to refinance or invest elsewhere.
How do families typically structure their guarantee exit?
Most families plan for guarantee removal within 2-5 years through natural capital growth and principal reduction. Once your child's property has grown in value and their loan balance has reduced sufficiently, they can refinance without family support.
The exit typically happens when your child reaches 80% loan-to-value ratio on their property, allowing them to avoid LMI on their new loan. In areas like Narraweena, where house prices have grown 12.81% over the past year, this timeline can be accelerated by favourable market conditions.

Frequently Asked Questions
Can grandparents provide a family guarantee on a Northern Beaches property?
Yes, most lenders accept guarantees from parents, grandparents, or other immediate family members. The key requirement is that the guarantor has sufficient equity in their property and stable income to support the arrangement.
How much deposit does my child need with a family guarantee?
Your child typically needs as little as 5% deposit with a family guarantee. The guarantee covers the deposit shortfall and LMI costs, allowing them to buy with minimal upfront cash while avoiding insurance premiums.
What happens if my child defaults on their family guarantee loan?
The lender can pursue both your child's property and your guaranteed property for repayment. This is why exit planning and conservative guarantee limits are crucial, as the arrangement should never put your own home at genuine risk.
Can I remove a family guarantee early?
Yes, once your child's property has sufficient equity or they can demonstrate capacity to service the full loan independently. Most lenders require the new loan-to-value ratio to be 80% or below before releasing the guarantee.
Do all lenders offer family guarantee home loans?
No, not all lenders offer family guarantee products, and terms vary significantly between those that do. Lender selection affects guarantee limits, exit conditions, and ongoing requirements for both parties.
Should Northern Beaches families use a mortgage broker or go direct to a bank for a guarantee loan?
A mortgage broker, every time. Each family's situation differs based on property equity, income stability, timeline, and risk tolerance. Professional comparison across 60+ lenders helps identify which lender's guarantee structure, exit conditions, and limits suit your specific circumstances best.
Can family guarantees be used for investment properties on the Northern Beaches?
Some lenders allow family guarantees for investment purchases, though terms are typically more conservative than owner-occupier guarantees. The arrangement works best when your child intends to live in the property initially.
Your Next Steps
Getting a family guarantee right requires more than good intentions. It needs proper structure, conservative limits, and a clear exit plan. The difference between lenders can affect guarantee requirements, exit conditions, and the risk to your own property, which is exactly what a broker comparison is designed to evaluate for your family.
