Family Guarantee Loans: Helping Families Buy a Home in Northern Beaches, Sydney

October 15, 2025

Buying a home in the Northern Beaches, Sydney, can feel out of reach for many first-time buyers, especially with rising property prices. Family guarantee loans are one way families are banding together to make it happen. These loans allow a family member—often a parent—to use their property as security to help the buyer meet loan requirements and avoid Lenders Mortgage Insurance (LMI).

That’s where local mortgage brokers come in. At Mortgage Brokers Northern Beaches, our brokers simplify the whole process. We help you compare home loans, deal with banks, and find the right loan, be it a family guarantee loan or an investment loan, tailored to your goals in the Northern Beaches property market.

Let’s take a closer look at how these loans work and how they can be the stepping stone to your new home.

What is a Family Guarantee Loan?

A family guarantee loan is a type of home loan where a family member, usually a parent, offers part of their property’s equity as additional security for your home loan. This means you don’t need a full deposit and can avoid LMI, which is typically required when borrowing more than 80% of the property value.

Key features include:

Lower deposit required (sometimes none at all).
Avoid LMI, potentially saving thousands.
Family member doesn’t give you cash; they just guarantee part of the loan.
The guarantee can be released once the borrower builds equity.

This setup is ideal for families who want to help their children get into the Northern Beaches property market without dipping into their own cash savings. However, it's important to understand the legal and financial obligations on both sides before jumping in.

For those not eligible, there are still options like low deposit home loans or first home buyer grants worth exploring.

Who Can Be a Guarantor?

The guarantor is usually a close family member, most commonly parents, but in some cases, siblings or grandparents may qualify, depending on the lender. They must have a strong financial standing, and often, their property must be located in Australia.

Here’s what lenders typically look for in a guarantor:

Good credit history
Sufficient equity in their home
Stable income and employment
Australian residency

While acting as a guarantor doesn’t mean making loan repayments, they are liable if the borrower defaults. That’s why getting professional advice and working with a mortgage broker is crucial. You can also learn about guarantor loan structures on our website to better understand how it works.

Benefits of Family Guarantee Loans for Buyers in Northern Beaches, Sydney

Family guarantee loans open up doors for buyers who may otherwise struggle to break into the housing market. Here are some of the main benefits:

1. Enter the market sooner

Avoid the long, slow process of saving a 20% deposit. Buyers can act faster when opportunities in the Northern Beaches arise.

2. Avoid costly LMI

LMI can cost thousands depending on the loan size. Using a family guarantee allows borrowers to skip this added cost.

3. Get a better interest rate

Lenders may offer more favourable terms if you're borrowing less compared to the property value.

4. Buy in desirable locations

With help from family, buyers might be able to afford a home in prime suburbs like Manly, Dee Why, or Freshwater.

Risks and Responsibilities for Guarantors

While these loans come with big benefits, they’re not without risks, especially for the guarantor.

Important risks include:

The guarantor’s property may be at risk if the borrower defaults.
Their own ability to borrow in the future may be impacted.
Emotional stress and potential tension within the family.

That’s why it's essential for both parties to have open conversations and seek legal and financial advice. Guarantors should fully understand their rights and responsibilities before signing anything.
