Can you use a guarantor to buy your first home with no deposit in 2026

Saving a 20% deposit is the single biggest barrier for first‑home buyers in 2026. With median house prices above $1.1 million in Sydney and $850,000 in Melbourne, a 20% deposit is $220,000 and $170,000 respectively – sums that take years to accumulate while rents keep rising.

One solution that has gained renewed attention in 2026 is the family guarantee loan, also called a guarantor loan. It allows you to buy with zero deposit by using a parent’s or relative’s home equity as security. But how does it stack up against government schemes like the First Home Guarantee (FHBG) after the July 2026 changes? And what risks do both parties face?

This article explains everything you need to know about using a guarantor to buy your first home with no deposit in 2026 – the mechanics, lender criteria, costs, risks, and real‑world alternatives.

How a family guarantee loan works in 2026

A family guarantee loan lets you borrow up to 100% of the property’s value without paying Lenders Mortgage Insurance (LMI). Instead of a cash deposit, a guarantor – usually a parent – offers a portion of their own home equity as additional security.

The mechanics in practice

· You find a property worth, say, $800,000. · Your lender agrees to lend 100% of the purchase price ($800,000) because your parents guarantee the top 20% (i.e., $160,000) using equity in their own home. · Your parents do not hand over any cash. They simply sign a limited guarantee deed that the lender can call on if you default. · You own the property outright but your parents’ equity is tied up until the loan‑to‑value ratio (LVR) on your loan falls below 80%.

In 2026, most major banks and non‑bank lenders offer family guarantee products. However, the Reserve Bank of Australia’s cash rate sits at 4.35%, and the lowest advertised variable rate is around 5.69% (for borrowers with strong credit and low LVR). For a guarantor loan at 100% LVR, expect a rate closer to 6.10%–6.50% because the risk to the lender is higher despite the guarantee.

Key point: The guarantee is typically limited to a specific dollar amount (e.g., $160,000) and for a set period, often 5–7 years, after which the guarantor can be released if your LVR has dropped to 80% or below.

Lender requirements for guarantor loans in 2026

Lenders have tightened criteria in 2026 due to APRA’s macro‑prential rules and the ongoing cost‑of‑living environment. Here’s what you and your guarantor need to meet.

Borrower requirements

· Credit score: Minimum 650, but most lenders prefer 700+. A score below 600 will likely be declined. · Income stability: At least 12 months continuous employment (or 2 years of self‑employed income). Casual workers need 12 months history with consistent hours. · Debt‑to‑income (DTI): APRA’s February 2026 cap of 6x means your total debt (including the new loan) cannot exceed 6 times your gross annual income. For a $800,000 loan, you need a minimum income of about $133,333 per year. · Serviceability buffer: The lender must apply a 3% buffer on the interest rate. With a rate of 6.50%, they assess your ability to repay at 9.50%. This significantly reduces borrowing capacity.

Guarantor requirements

· Age: Usually under 65 at loan start, though some lenders accept up to 70 if the guarantee is limited. · Property equity: Must have at least 20% equity in their own home after the guarantee is registered. If their home is worth $1 million and the guarantee is for $160,000, they need a mortgage balance below $640,000 (i.e., at least $360,000 equity). · No adverse credit history: The guarantor must have a clean credit file. A default or bankruptcy in the last 5 years will disqualify them. · Income: The guarantor must demonstrate that they can afford the guaranteed portion if you default. Some lenders calculate this as a separate serviceability test.

Which lenders offer guarantor loans in 2026?

· Big four banks: Commonwealth Bank (Family Guarantee), Westpac (Family Guarantee), NAB (Family Equity Pledge), ANZ (Home Secure – discontinued in some states but available under Family Pledge). · Regional banks: Bankwest, Suncorp, Bendigo Bank, and Teachers Mutual Bank all offer family guarantee products. · Non‑bank lenders: Pepper Money, Resimac, and FirstMac have limited guarantee options, usually with higher rates.

Note: Not all lenders allow complete 100% LVR. Some cap the guaranteed amount at 20% of the property value, meaning you still need a 5% genuine savings deposit. In 2026, NAB and Westpac are the most flexible for zero‑deposit scenarios.

Comparing guarantor loans with the First Home Guarantee (FHBG)

The FHBG was updated on 1 July 2026. Here’s how the two options compare for a first‑home buyer buying a $800,000 property.

First Home Guarantee (FHBG)

· Deposit required: 5% ($40,000) – you must have genuine savings. · No LMI: The government guarantees the top 15%, so you avoid LMI costs. · Price caps (from July 2026): Sydney $1.5M, Melbourne $950k, Brisbane $1M, Perth $850k, Adelaide $750k, Canberra $900k, Darwin $600k, Hobart $650k. · Income cap: None from July 2026 – any income level is eligible. · Place cap: 35,000 places per financial year. As of July 2026, about 15,000 places still available for 2026‑27. · Rate: You get the lender’s standard variable rate (approx. 5.69% for low‑LVR borrowers, but with 95% LVR you may pay around 6.10%–6.30%). · Equity release: You must live in the property (owner‑occupier only).

Guarantor loan (no deposit)

· Deposit required: 0% – no genuine savings needed. · No LMI: The family guarantee replaces LMI. · Price cap: None – can buy any property up to your borrowing capacity. · Income requirement: Stricter due to DTI cap – you need income high enough to keep DTI ≤ 6x. · Rate: Typically higher – around 6.40%–6.80% because of the 100% LVR. · Equity release: The guarantor’s equity is tied up, potentially limiting their own borrowing (e.g., for renovations or retirement). · Risk to guarantor: If you default, the lender can sell their property to recover the guarantee amount.

Which is better? If you have a 5% deposit and your property is within the price cap, the FHBG is generally cheaper and safer for both you and your family. If you have no deposit at all and your income is high enough to satisfy the DTI limit, a guarantor loan may be the only way to enter the market sooner.

Risks for the guarantor and the borrower

Family guarantee loans are not without significant risks. Both parties need to understand the consequences before signing.

Risks for the borrower

· Higher interest rate: At 100% LVR, you pay a premium compared to a 95% LVR loan. Over a 30‑year loan, the difference of 0.5% on $800,000 adds about $60,000 in extra interest. · Negative equity risk: If property prices fall, you could owe more than the home is worth. The guarantor may be forced to cover the shortfall. · Strained relationship: If you struggle to repay, the guarantor’s home is at risk. Financial stress can damage family ties. · Exit difficulty: Refinancing to remove the guarantor requires you to have 80% LVR. With flat prices, that could take 5–7 years, or require a lump‑sum payment.

Risks for the guarantor

· Loss of equity: The guarantee amount is registered as a mortgage over their property. They cannot refinance, sell, or use that equity without the lender’s consent. · Liability for default: If the borrower stops paying, the lender can demand the guaranteed amount immediately. In a worst‑case scenario, the lender can force the sale of the guarantor’s home. · Impact on retirement planning: Guarantors aged 55+ may find it harder to access reverse mortgages or downsize because the guarantee ties up equity. · Credit risk: The guarantee appears on the guarantor’s credit report. If the borrower defaults, the guarantor’s credit score is damaged.

Important: Get independent legal advice before signing any guarantee. Both parties should have separate solicitors.

Steps to apply for a guarantor loan in 2026

If you decide a guarantor loan is right for you, follow these steps.

1. Assess your borrowing capacity – Use a mortgage calculator or speak to a broker. With the DTI cap of 6x, your maximum loan is 6 times your income. For a $800,000 loan, you need $133,333 income.

2. Choose a lender – Compare big banks and regional banks. NAB and Westpac are popular for zero‑deposit guarantees.

3. Get pre‑approval – Provide payslips, tax returns, bank statements. The lender will also assess your guarantor’s financials and property valuation.

4. Find a property – Ensure it is within your approved borrowing limit and meets the lender’s security criteria (no high‑rise or unique properties).

5. Final approval and settlement – The lender registers a caveat or mortgage over the guarantor’s property. Settlement proceeds as normal.

6. Plan to remove the guarantor – Aim to pay down the loan to 80% LVR as quickly as possible. Some lenders allow partial release after 5 years if LVR is below 90%.

Alternatives to a guarantor loan

A guarantor loan is not the only path. Consider these options in 2026.

· First Home Guarantee (FHBG) – As discussed, requires 5% deposit but no income cap and no family risk. Best if you have savings. · First Home Super Saver Scheme (FHSSS) – You can contribute up to $15,000 per year (capped at $50,000) into super and withdraw for a deposit. With salary sacrifice, you can build a 5% deposit faster while saving tax. · Family pledge with cash deposit – Some lenders allow a parent to pledge equity to cover LMI only, while you still provide a 20% deposit. This reduces the guarantor’s exposure. · Shared equity schemes – In 2026, some state governments (e.g., NSW Shared Equity Home Buyer Helper) offer co‑ownership with zero deposit. Eligibility is income‑capped (under $100,000 for singles, $130,000 for couples) and price caps apply. · Rent‑vesting – Buy an affordable investment property in a cheaper area while renting where you want to live. Requires a 10–20% deposit but no income cap.

Frequently asked questions

1. Can I buy a house with no deposit and no income in 2026? No. While a guarantor covers the deposit, you still need sufficient income to service the loan at the assessed rate (current variable rate plus 3% buffer). With rates around 6.5% and buffer at 9.5%, you need a gross income of roughly $130,000 for an $800,000 loan.

2. How much does a guarantor loan cost in interest over 30 years compared to a 5% deposit FHBG loan? Assuming a loan of $800,000: Guarantor loan at 6.60% (total interest ≈ $1,045,000). FHBG loan at 6.10% with 95% LVR (loan $760,000 plus $40,000 deposit) total interest ≈ $895,000. The difference is about $150,000 over 30 years.

3. Can my parents act as guarantor if they are retirees with no income? Most lenders require the guarantor to have income to cover the guaranteed amount if you default. Retirees relying on the Age Pension may not pass the serviceability test. Some lenders allow asset‑based assessment (e.g., having $500,000 in super or shares), but this is rare. A better option is a family pledge where equity alone is used, but it still requires the guarantor to have no excessive debt.

4. What happens if property values drop and I owe more than the home’s worth? The guarantor is liable for the shortfall up to the limited amount. If you default and the sale proceeds are $750,000 on an $800,000 loan, the guarantor must pay $50,000. If the guarantee is capped at $160,000, you and the guarantor are protected beyond that cap, but you still lose the home.

5. Can I use a guarantor to avoid paying LMI on an investment property? Some lenders allow family guarantees for investment properties, but most restrict the product to owner‑occupiers. If allowed, the rate is typically higher (above 7%) and the guarantor must have significant equity. The FHBG is not available for investment properties.
