With Perth’s median house price now above $880,000 and the RBA cash rate at 4.10% as at March 2026, saving a 20% deposit has become an increasingly long-term goal for many first home buyers. A guarantor home loan Perth offers a practical shortcut – one that uses a family member’s existing property equity in place of part or all of your deposit, eliminating the need for Lenders Mortgage Insurance (LMI) and getting you into the market years earlier than saving alone.
This guide explains exactly how a guarantor loan works, who can be a guarantor, how much you can borrow, what the legal requirements are in 2026, and – critically – how to plan and execute the exit strategy that releases your guarantor once your equity position is strong enough.
A guarantor home loan Perth is a home loan where a family member – most commonly parents – offers equity in their own property as additional security for your loan. Rather than your parents handing over cash, they allow the lender to place a charge over a portion of their property. This provides the lender with enough security to approve your loan without requiring a 20% cash deposit and without charging LMI.
Most guarantor home loan Perth arrangements are structured as a limited guarantee – meaning your guarantor is only liable for a specific portion of the loan, typically around 20% of the property value. This is far safer than an unlimited guarantee and is now the standard approach recommended by brokers and ASIC in 2026.
Example: You are purchasing a $700,000 property in Perth. A 20% deposit would be $140,000 – an amount many buyers cannot save while renting. Under a limited guarantor structure, your parents guarantee $140,000 of the loan using equity in their own home. You borrow the full $700,000, LMI is not charged, and your parents’ exposure is capped at the $140,000 guaranteed amount.
Most lenders in 2026 accept immediate family members as guarantors. In the context of a parents guarantor first home buyer Perth arrangement, both parents and step-parents are typically accepted. Siblings, grandparents, and adult children are accepted by some lenders depending on their policy.
To qualify as a guarantor, your family member must:
Importantly, being a guarantor will affect your parents’ own borrowing capacity. If they are planning to refinance, invest, or downsize within the next few years, the guarantee must be factored into their financial planning. A good broker discusses this with all parties before any structure is agreed.
A Guarantor Home Loan Perth can allow you to borrow up to 105% of the property purchase price – covering the purchase price plus costs such as stamp duty, conveyancing fees, and other upfront expenses. This is only possible because the lender has additional security through the guarantee, reducing its risk on the overall exposure.
In practice, the amount you can borrow is still governed by serviceability – your income, existing debts, living expenses, and the lender’s assessment rate. With the RBA cash rate at 4.10% and standard variable rates between 5.6% and 5.9% as at March 2026, lenders apply a buffer of approximately 3% above the current rate when stress-testing your ability to repay. The guarantor does not increase your borrowing capacity based on income – only their property equity provides the additional security.
The Guarantor Home Loan Perth has become one of the most commonly requested structures at Strawberry Finance in early 2026. With REIWA forecasting Perth median house price growth of more than 10% over 2026 – following years of sustained growth that have pushed prices above $880,000 – the deposit gap has become generational.
At Perth’s current median, a 20% deposit represents approximately $176,000 in cash savings – before costs. For a 30-year-old earning $100,000, saving this amount while paying rent in Perth could realistically take 8 to 10 years at conservative savings rates. The guarantor structure collapses that timeline to the point of the buyer’s first contract, provided a family member has the equity and the willingness to assist.
Perth’s property price growth also creates a natural tailwind for the exit strategy – as prices rise, the LVR on the borrower’s property decreases faster than repayments alone would achieve, bringing the 80% LVR release threshold forward.
The most important conversation missing from most guarantor loan arrangements is the exit strategy – and this is where parents guarantor first home buyer Perth arrangements so often go wrong. A guarantee is not meant to last for 30 years. A clear, documented exit plan protects your parents, reduces their financial exposure, and gives both parties a milestone to work towards.
The guarantee can be released once your loan reaches an LVR of 80% – meaning you owe 80% or less of your property’s current market value. This is achieved through:
To release the guarantee, you apply formally to your lender. The lender orders a new valuation of your property, confirms the LVR is at or below 80%, and assesses that you can service the full loan independently. If approved, a Substitution of Security or Release of Guarantee is executed and your parents’ property is discharged from the loan.
In Perth’s current market, with REIWA forecasting continued price growth through 2026, many borrowers who entered guarantor arrangements in 2022–2024 are already approaching or achieving release threshold, supported by the strong capital growth of the past few years.
Every lender in Australia now requires guarantors to obtain independent legal advice before a guarantor loan can proceed. This is not optional – it is a formal requirement. Your parents will need to attend a separate appointment with a solicitor or conveyancer who explains their obligations, rights, and risks before signing.
Independent legal advice protects both the guarantor and the lender. ASIC requires it as part of the responsible lending framework, and any guarantor who does not receive it can potentially challenge the enforceability of the guarantee later. Build the cost and timing of legal advice into your application timeline.
At Strawberry Finance, our approach to every guarantor structure starts with a three-party conversation – the borrower, the guarantor, and us. We review the guarantor’s equity position and borrowing situation alongside the borrower’s income and serviceability, and we model the exit strategy upfront so all parties know exactly when the guarantee is expected to be released.
We also confirm the lender’s specific limited guarantee structure before any application is submitted. Different lenders handle guarantor releases differently – some process them quickly and cleanly, others create delays and conditions. Choosing the right lender from the start makes the exit simpler when the time comes.

No. Your guarantor needs sufficient equity – the difference between their property value and their outstanding mortgage balance – to cover the guaranteed portion of your loan. A guarantor with a $700,000 property and a $400,000 mortgage has $300,000 in equity, which may be more than enough to support a 20% limited guarantee depending on your purchase price.
In most cases, lenders will only release a guarantor at 80% LVR to avoid LMI on the remaining loan. Some lenders will release at 90% LVR, but LMI becomes payable at that point. We model both scenarios and advise on the most cost-effective release timing for your specific situation.
Yes, it is one of the most requested structures in our Perth practice in 2026. With Perth median prices above $880,000, the deposit gap has become very large for most first home buyers. This family guarantee structure bridges that gap efficiently, provided the exit strategy is planned from day one.
If the borrower defaults, the lender will first seek to recover the debt from the borrower’s property. If a shortfall remains after the sale of the borrower’s property and it falls within the guaranteed amount, the lender may pursue the guarantor’s property for that shortfall. This is the core risk all guarantors must understand before signing — and why independent legal advice is mandatory.
Yes. The FHOG (First Home Owner Grant) of $10,000 in WA and eligibility for the FHBG (5% deposit federal guarantee) are separate schemes. A guarantor arrangement does not disqualify you from the FHOG, provided you meet the standard WA eligibility criteria – Australian citizen or permanent resident, never previously owned property, new home under $750,000.
As long as the LVR remains above 80% and no formal release has been applied for. The guarantee does not automatically end – you must actively apply for release. This is why we set a clear target date and equity milestone at the start of every guarantor arrangement. In Perth’s current property market, most borrowers reach the 80% LVR threshold within 3 to 6 years.
There are options. The guarantee can potentially be moved to a new property your parents purchase, provided there is sufficient equity in the new property. Alternatively, the loan can be restructured. These situations are manageable with advance planning – which is why the exit strategy conversation should happen before the loan is set up, not after a complication arises.
A limited guarantee caps your guarantor’s liability to a specific dollar amount-typically around 20% of the purchase price-helping bring your LVR to 80% and avoid LMI. With guidance from Strawberry Finance, this approach is far safer than an unlimited guarantee, where the guarantor is responsible for the entire loan if the borrower defaults. In 2026, most lenders and brokers recommend limited guarantees as the standard structure for added protection.
