Family pledge / family guarantee

Saving the deposit for a first home can be difficult and may take many years.

One way some borrowers may be able to enter the property market sooner is by having a family member act as a .

Many lenders allow parents or other close family members to use the equity in their property as security for part of a home loan, instead of the borrower needing to save the full deposit.

The person providing this support is known as a .

How does it work?

With a family pledge guarantee, a family member offers part of the equity in their property as security for your loan.

This can reduce the deposit required and may allow you to avoid paying Lenders Mortgage Insurance (LMI).

Example

If you are buying a property for $600,000:

  • A 5% deposit would be $30,000
  • To avoid LMI, a 20% deposit of $120,000 would usually be required

This means you would normally need to save an additional $90,000.

If your parents own a property valued at $900,000 and have sufficient equity, they may offer $90,000 of their equity as security for your loan — , but as additional security.

This allows the lender to treat the loan as though you have a 20% deposit, even though you have only contributed 5% in cash.

Once the equity in your property reaches 20%, you and your parents can apply to the lender to have the guarantee released.

The guarantor’s property does secure the entire loan — only the guaranteed portion.

How is this different to being a co-borrower?

A is responsible for the entire loan until it is fully repaid.

A is only responsible for the specific amount covered by the guarantee.

Once the guarantee is released, the guarantor has no further responsibility, even though the loan continues.

Who can be a guarantor?

Guarantors are generally limited to immediate family members, such as:

  • parents
  • grandparents
  • siblings

The guarantor must usually:

  • have sufficient equity in their property
  • demonstrate an acceptable financial position

For example, if a guarantor’s property is valued at $900,000 but they owe $800,000, there may not be enough equity available to support a guarantee.

Benefits for first home buyers

A family guarantee may:

  • help avoid or reduce Lenders Mortgage Insurance (LMI)
  • reduce the amount of savings required for a deposit
  • allow entry into the property market sooner
  • enable purchase of a preferred property rather than a lower-priced alternative

It is important to note that the borrower must still be able to service the from their own income.

Considerations for guarantors

Being a guarantor is a significant financial commitment and involves risk.

If the borrower is unable to meet loan repayments, the guarantor may be required to cover the guaranteed portion of the loan.

In serious cases, this could place the guarantor’s own property at risk.

This is particularly important for guarantors approaching retirement, as their financial position could be impacted if repayments need to be made on behalf of the borrower.

Understand your obligations

Both the borrower and the guarantor must clearly understand:

  • how much of the loan is guaranteed
  • when the guarantee can be released
  • what happens if repayments cannot be met

Most lenders require guarantors to obtain before entering into a guarantee.

This helps ensure everyone understands the risks and obligations involved.

Why Underwriters Focus Here

The guarantor's property secures only the guaranteed portion of the loan, not the full balance. Lenders assess the guarantor's equity position and their ability to service the guarantee if called upon. Once the borrower's equity reaches 20%, the guarantee can typically be released — but only after a formal application and property valuation. Lenders require guarantors to seek independent legal and financial advice before signing.

Key Outcome Assessment Factors

The amount of usable equity in the guarantor's property, whether the guarantor still has an active mortgage, the guarantor's income and financial position, and the borrower's ability to service the full loan amount from their own income — not the guarantor's.
