Home Loans With A Guarantor Overview
A guarantor home loan allows a borrower to purchase property without needing a full cash deposit by using a family member’s property equity as additional security for the loan.
Instead of saving a traditional 20% deposit, the borrower can often enter the property market immediately by leveraging the guarantor’s equity. This structure reduces or completely removes the need for Lenders Mortgage Insurance (LMI), which can otherwise cost tens of thousands of dollars.
In many cases, guarantor loans allow borrowers to access up to 100%–110% of the property value, depending on lender policy, borrower profile, and guarantor equity strength.
This type of lending is most commonly used by:
- First-home buyers with a stable income but low savings
- Young professionals entering the property market
- Borrowers who want to avoid LMI costs
- Families supporting children into homeownership
What Is A Guarantor?
A guarantor is a financially stable individual, usually a close family member, who agrees to use the equity in their own property as security for someone else’s home loan.
The guarantor does not own the property being purchased and does not receive any financial benefit from it. Instead, they provide a legal guarantee to the lender that they will cover part or all of the loan if the borrower is unable to repay it.
Key Responsibilities Of A Guarantor
- Provides security using home equity
- Reduces lender risk exposure
- Helps borrowers avoid or reduce deposit requirements
- May eliminate the need for LMI
- Becomes legally responsible for the guaranteed portion if the borrower defaults
What A Guarantor Does NOT Do
- Does not live in the property
- Does not make monthly repayments (unless borrower defaults)
- Does not gain ownership rights
- Does not receive rental income or capital gains
Who Can Be A Guarantor?
Lenders typically require a strong familial relationship and a stable financial position.

How Guarantor Loans Work
Guarantor loans function by using the equity in a family member’s property to reduce the borrower’s loan-to-value ratio (LVR).
This allows the borrower to avoid LMI and secure financing with little or no deposit.
Loan Structure Breakdown
Most lenders structure guarantor loans as a limited guarantee, meaning:
- Guarantor secures only part of the loan (usually 20%)
- The borrower is still the primary responsible party
- Guarantor liability is capped, not unlimited
- Security reduces over time as the borrower builds equity
Example Scenario (Detailed Breakdown)
| Item | Value |
|---|---|
| Property Price | $600,000 |
| Borrower Deposit | $60,000 (10%) |
| Shortfall to 20% | $60,000 |
| Required Guarantee | $60,000 equity |
In this case:
- Guarantor uses equity from their home
- Borrower avoids LMI (~$10,000–$20,000+)
- Loan proceeds at a higher LVR approval level
Release Mechanism
Guarantors are usually released when:
- Borrower reaches 20% equity naturally, OR
- The loan is refinanced into a standalone structure
