“A parental guarantee is a highly effective entry strategy. However, it is a real financial obligation that requires careful structure and independent advice.”
A family guarantor arrangement allows a parent (or other close family member) to use equity in their own property to support your home loan application. This can reduce or eliminate the deposit you need and remove the LMI requirement, significantly shortening the time to purchase.
How the guarantee works
Your parents’ property is used as additional security for your loan. The lender takes a mortgage over both your property and a portion of your parents’ property. The guarantee is typically limited to the portion of the loan needed to reduce your LVR to 80% — not the full loan amount. This is called a limited guarantee.
What parents actually commit to
If you default on the loan, the lender can call on the guarantee — which means your parents’ property is at risk. This is real and the implications need to be understood clearly before proceeding. Most lenders require guarantors to obtain independent legal and financial advice before the guarantee is registered.
The 2026 context
Three rate rises in 2026 have made saving a 20% deposit take even longer. For first home buyers with parents who own their home outright or with significant equity, the guarantor route bypasses the deposit barrier entirely — allowing entry into the market at current prices rather than after a further 2–4 years of saving.
When the guarantee is released
The guarantee is released once your LVR falls to 80% through principal repayments, property value growth, or a combination of both. Depending on your loan and the market, this typically occurs within 3–7 years. An accelerated release can be triggered by making extra repayments or demonstrating a significant increase in property value through a formal valuation.
