Buying With a Small Deposit: Guarantors, Guarantee Schemes and LMI, Explained
There isn't one door into home ownership — there are three. LMI, 5%-deposit guarantee schemes and guarantor loans, compared honestly.

- Path 1 (Paying LMI): Paying LMI can be the fastest, most economical path when target property price appreciation exceeds savings velocity.
- Path 2 (Government Guarantee Schemes): Federal backing allows eligible first home buyers to purchase with 5% deposit and zero LMI.
- Path 3 (Guarantor Loans): Allows parents to pledge home equity as security, reducing deposit needs to 0% without transferring cash.
- A responsible guarantor structure must always feature a limited guarantee cap, an exit milestone, and independent legal advice.
- Select occupations (e.g. medical practitioners, nurses, lawyers) qualify for specialized bank LMI waivers.
Path 1: Pay LMI and buy sooner
Lenders Mortgage Insurance is a one-off premium you pay when borrowing more than 80% of a property's value. Two things about it are widely misunderstood:
The premium scales with how little deposit you have and how much you're borrowing, it can often be added to the loan, and — a detail few buyers hear — some professions and some lenders have LMI waivers or discounts. Which is exactly the kind of policy quirk a whole-of-market broker exists to find.
- It protects the lender if you default — not you. You're paying for their peace of mind.
- It is not automatically a rip-off. If paying LMI gets you into a rising market two years earlier, the premium can cost far less than the price growth you'd have missed. Sometimes it's the smartest money in the whole transaction.
Path 2: Government guarantee schemes — 5% down, no LMI
Under the federal Home Guarantee Scheme, the government effectively stands behind part of your loan so that eligible buyers can purchase with as little as a 5% deposit without paying LMI. Variants have existed for first home buyers, regional buyers and single parents (with even lower deposit requirements for the latter).
The catches are real but manageable: property price caps, income tests, owner-occupier requirements — and the details change with budgets and elections. Two rules of thumb:
Never rule yourself out from memory, and never rely on a two-year-old article. Eligibility is a ten-minute check against current rules — have someone run it before you set your budget.
Path 3: A guarantor — the family shortcut, taken seriously
A guarantor loan lets a family member — usually a parent — offer equity in their own home as extra security for yours. Done well, it can shrink or remove the deposit hurdle and dodge LMI entirely, all without your parents handing over cash.
But we won't sugar-coat it: a guarantee is a real legal commitment. If the loan goes bad, the guarantor's own home backs the shortfall. So a responsible guarantor setup always includes:
- A limited guarantee — capped at a specific amount, never 'everything.'
- An exit plan — the guarantee gets released once your equity reaches a safe level, typically after a few years of repayments and growth.
- Independent advice for the guarantor — lenders generally require it, and good brokers insist on it. If anyone waves this away, walk.
Which path is yours?
It depends on the numbers: your savings, your income, your family's situation, the property, and what each option costs over its life — not just at settlement.

Common Questions Answered
How does a guarantor loan work in Australia?
A guarantor (typically a parent) uses the equity in their property as security for a portion of your loan, enabling you to borrow up to 100% of the purchase price without paying LMI.
When can a guarantor be removed from my home loan?
A guarantor can be formally discharged once your property's value rises or you pay down the loan so your Loan-to-Value Ratio (LVR) drops to 80% or below.
