Guarantor Home Loans
Guarantor Home Loans can be an important part of a broader borrowing strategy. At Derwent Finance, we help Australian borrowers understand their options, compare suitable lenders from our panel and structure finance around the outcome they are trying to achieve — not simply around a headline rate.
This page is for people researching guarantor home loans and related options such as family guarantor home loan, parent guarantor home loan, family guarantee mortgage. It explains how this type of finance generally works, who it may suit, the issues that can affect lender approval, common scenarios and the steps involved from initial review through to settlement or funding.
Every application is assessed on its own facts. Property or asset value, income, expenses, existing debts, credit conduct, entity structure and lender policy can all change the outcome. The information below is general and is designed to help you ask better questions before choosing a lender or loan structure.
Who This Is For
- First home buyers with strong income but limited savings
- Buyers whose parents want to help without gifting the full deposit
- Borrowers seeking to reduce or avoid LMI where eligible
- Families wanting a limited guarantee
- Eligible established-home or new-build buyers
A family guarantee can reduce the deposit barrier
A guarantor structure can allow an eligible family member to provide additional property security for a limited portion of the purchase. This may help a buyer purchase with a smaller cash deposit and, in some structures, reduce or avoid Lenders Mortgage Insurance. The guarantor is taking on a real financial obligation, so the structure should be understood by everyone involved.
A limited guarantee is different from guaranteeing the whole debt
Many family-guarantee products are designed so the guarantor supports only the amount needed to bring the loan within a target lending ratio rather than guaranteeing every dollar borrowed. The exact guarantee amount and security structure vary by lender.
There should be a plan to release the guarantee
The guarantee does not necessarily need to remain for the entire home-loan term. If the borrower reduces the loan or the property value increases sufficiently, the lender may allow the additional security to be released after a fresh assessment. Release is not automatic, so it should be reviewed once the borrower reaches an appropriate equity position.
Our Approach
How We Can Help
We start by understanding the full scenario and what you want the finance to achieve. Depending on the transaction, our work can include:
- Calculate the purchase price, borrower deposit and costs
- Assess borrower servicing
- Estimate the required guarantee amount
- Review the guarantor property and mortgage
- Compare lender guarantee policies
- Explain independent legal advice requirements
- Plan for possible future release of the guarantee
Real Situations
Common Scenarios
Family guarantees are commonly used where income is sufficient but the buyer has not yet built a large deposit. Examples include:
- Parents helping a first home buyer
- Borrower has some savings but less than 20%
- Reducing or avoiding LMI
- Guarantor still has a mortgage
- Releasing the guarantee later

Why Derwent Finance?
A loan approval is only one part of the process. Derwent Finance focuses on understanding the objective, comparing lender policy and helping manage the application from initial strategy through to settlement. We assist borrowers across Australia with home loans, refinancing, investment, construction, self-employed, complex, commercial and business finance scenarios.
Where the best outcome is to keep an existing loan or wait until the borrower’s position changes, the recommendation should reflect that rather than moving a loan simply to create a transaction.
