In many families — especially in South and Southeast Asian communities across Sydney — buying your first home is a family achievement, not just an individual one. A guarantor loan is how that family support translates into real mortgage outcomes: zero deposit, zero LMI, and getting into your own home years earlier. Here's everything you need to know.

What Is a Guarantor Loan?
A guarantor loan is a home loan where a family member — typically a parent — uses the equity in their own property as additional security for your loan. This covers the gap between your deposit and the standard 20% LVR threshold that lenders require to avoid LMI.
The key thing to understand: your parents don't give you any money. They don't transfer cash to your account. They don't appear on your title. They simply allow their home to be used as security alongside yours — a formal legal arrangement with the lender.
Because the lender now has additional security covering the full purchase price, they treat your loan as low-risk. No LMI is charged. In many cases, you can borrow 100% of the purchase price plus costs.
How a Guarantor Loan Works — Step by Step
Your parents agree to be guarantors
They offer equity in their own home as additional security. They must own property in Australia (not overseas) and have sufficient equity available.
A broker structures the loan
Not all lenders offer guarantor loans and policies vary significantly. A broker finds the lender with the best terms for your specific family situation.
Both you and your parents are assessed
Lenders assess your income (you repay the loan), your parents' property (it's the security), and everyone's credit file.
Loan approved — you buy the property
Your parents sign a limited guarantee deed. Their home is registered as additional security on your loan at settlement.
You make all the repayments
Your parents make no payments. The loan is entirely yours. They are only involved if you were to default — which is why this arrangement requires trust and responsibility.
Guarantee released when LVR reaches 80%
Once your loan balance drops below 80% of your property's value (through repayments and/or growth), you apply to remove the guarantee. Parents' property is released. They are no longer involved.
Who Can Be a Guarantor?
Most lenders restrict guarantors to immediate family members. Accepted guarantors typically include:
- Parents (most common)
- Step-parents
- Siblings (some lenders)
- Grandparents (some lenders, subject to age policy)
- De facto partners' parents (some lenders)
Friends, uncles, aunties, and cousins are generally not accepted as guarantors. The relationship must be direct family. Each lender has their own policy, and a broker knows which lenders are most flexible for your specific family structure.
What Do Your Parents Need to Qualify as Guarantors?
Your parents must meet the following conditions:
- Own property in Australia — the guarantor security must be an Australian property. Overseas properties are not accepted.
- Have sufficient equity — most lenders require the guarantor property to be at 80% LVR or below after the guarantee is applied. If your parents have a large mortgage themselves, there may not be enough free equity.
- Have a clean credit file — guarantors are credit-checked. Defaults or serious issues on your parents' file can affect the application.
- Be of working age or have adequate income — some lenders have age restrictions (e.g. guarantor must be under 70 or 75 at loan maturity). Retired parents may still qualify depending on their assets and equity position.
- Seek independent legal advice — lenders require guarantors to obtain independent legal advice before signing. This is a legal protection for your parents to ensure they understand what they're agreeing to.
The Equity Calculation
Say your parents own a home worth $900,000 with a $300,000 mortgage. Their accessible equity at 80% LVR is: ($900,000 × 80%) − $300,000 = $420,000 available. If you're buying an $800,000 property, the guarantee needed is $160,000 (the 20% gap). Your parents have more than enough equity. The guarantee only affects $160,000 of their $420,000 accessible equity.
Limited vs Unlimited Guarantee — This Matters
Always insist on a limited guarantee. Here's the difference:
- Limited guarantee: Your parents' liability is capped at a specific dollar amount — usually the difference between your deposit and 20% of the purchase price. Once your loan reaches 80% LVR, the guarantee is easily released. Most responsible lenders offer this.
- Unlimited guarantee: Your parents are liable for the entire loan. If you default and the property sells for less than the outstanding loan amount, your parents are responsible for the shortfall — up to the full loan value. This is riskier and should be avoided where possible.
A good broker will specifically structure a limited guarantee and choose a lender who supports this. This protects your parents and makes releasing the guarantee much simpler.

Guarantor Loans in the South Asian and Muslim Community Context
In Bangladeshi, Pakistani, Indian, and Sri Lankan families across Sydney — particularly in Lakemba, Bankstown, Liverpool, Fairfield, and Auburn — family financial support is not unusual. Parents regularly help children with deposits, living costs, and major life purchases.
A guarantor loan formalises that support in a way that:
- Doesn't require parents to liquidate savings or investments
- Doesn't disrupt parents' retirement planning
- Doesn't create informal debt arrangements within the family
- Has a clear, legally defined exit (the guarantee release) that removes parents from the picture once you're established
Many families in these communities are also navigating Islamic finance considerations. We cover Islamic-compliant home loan options in our Islamic finance page — and can discuss whether conventional guarantor structures are compatible with your family's values and circumstances.
Can You Combine a Guarantor Loan with the First Home Guarantee?
No — these two schemes cannot be combined. The First Home Guarantee (FHBG) already provides a government-backed guarantee for the 15% gap. Adding a family guarantee on top is not necessary and not permitted. You must choose one or the other:
| Feature | First Home Guarantee (FHBG) | Family Guarantor Loan |
|---|---|---|
| Min. deposit | 5% genuine savings | 0% (if parents have equity) |
| LMI | $0 | $0 |
| Income cap | $125K single / $200K couple | None |
| Price cap | $900,000 (Sydney) | None |
| First home buyer required | Yes — both applicants | No |
| Parents' property needed | No | Yes — must have equity |
| Best for | First home buyers with 5% saved, under income cap | Strong income, no deposit, parents own property |
The practical guide: if you're a first home buyer under the income threshold with 5% saved, the FHBG is simpler and keeps parents uninvolved. If you have strong income but minimal savings and your parents own property, a guarantor loan gets you in faster. Your broker will recommend the right path after assessing both.
Risks and How to Manage Them
A guarantor arrangement is a serious commitment. These risks are real and must be discussed openly with your family:
- If you default: Your parents are liable for the guaranteed amount. The lender can pursue them for the shortfall. This is the most serious risk and why guarantor loans should only be entered when your income is stable and repayments are comfortably affordable.
- Parents' borrowing capacity is affected: While the guarantee is active, it appears as a contingent liability on your parents' credit file. If they want to refinance or borrow during that period, the guarantor obligation may limit their options.
- Family relationships under financial stress: If repayments become difficult and parents feel at risk, it can create tension. Open communication, adequate insurance (income protection, life insurance), and a clear plan to release the guarantee within a defined timeframe are essential.
Protect Everyone with Insurance
Before settling a guarantor loan, make sure you have income protection insurance in place. If you lose your job or become ill and can't make repayments, income protection covers you — and by extension protects your parents' equity. This is non-negotiable for responsible guarantor arrangements.
How Quickly Can You Release the Guarantee?
The guarantee release timeline depends on two factors: your loan repayments and your property's growth. Both reduce your LVR. Here's a rough illustration:
| Purchase Price | Annual Growth | Repayments Only | Repayments + 5% Growth |
|---|---|---|---|
| $750,000 (100% loan) | — | ~8–10 years to 80% LVR | ~3–4 years to 80% LVR |
| $750,000 (20K own savings) | — | ~7 years | ~2–3 years |
Illustrative. Based on 6.2% rate, 30-year P&I loan. Property growth accelerates the guarantee release dramatically.
In growth corridors like Campbelltown, Leppington, and Oran Park — where 5–8% annual growth has been the norm — buyers have typically been able to release the guarantee within 3–5 years. The property's own growth does most of the work.
Gifted Deposit vs Guarantor — What's the Difference?
Sometimes parents prefer to give cash rather than use their property as security. Both are valid:
- Gifted deposit: Parents transfer cash to your bank account as a gift (not a loan). You need a gift letter confirming repayment is not required. Most lenders still require some genuine savings from you alongside the gift — typically 5% of the purchase price. The gift can make up the rest of the deposit.
- Guarantor loan: Parents use equity, not cash. No funds are transferred. More suitable for parents who are asset-rich but cash-poor, or who don't want to affect their own liquidity.
Some families do both: a partial gift plus a guarantor arrangement. This can give you both a deposit and LMI coverage in a single structured loan. The exact combination depends on how much equity and cash your parents have available.
