Guarantor Loan vs the 5% Deposit Scheme: Which Wins in 2026?

The Right Family, the Wrong Tool

A couple came to us with $40,000 saved, solid jobs, and parents offering to go guarantor. Sensible family, generous offer, and — on the numbers — the wrong tool.

Their borrowing power was $720,000, which capped their loan no matter whose equity backed it. When we ran both paths side by side, the Australian Government’s 5% Deposit Scheme delivered a similar purchase path — no LMI under the Scheme conditions and a small deposit — with one enormous difference: zero liability on mum and dad.

That comparison has changed shape since 1 October 2025, when the scheme (formerly the Home Guarantee Scheme) removed its income caps and place limits. A lot of guarantor content online — including some very established competitor guides — hasn’t caught up: it still treats “no deposit saved” as a problem only a guarantor can solve. In 2026, for most owner-occupier first home buyers, that’s no longer true.

Here’s the honest head-to-head, and the four situations where a guarantor still clearly wins. (Part of our complete guarantor guide.)

The Head-to-Head

Settings as at July 2026 and subject to change — check current scheme details at firsthomebuyers.gov.au. Lender policies differ and change without notice.

When the Scheme Wins

If all three of these are true, the scheme may be the cleaner option: you have (or can save) the required deposit, your target price is under your area’s cap, and you’ll live in the property. You may get the same headline benefit as a suitable guarantor structure — no LMI — without asking your parents to put their home behind your mortgage. When we present both options side by side with those conditions met, the scheme is often the cleaner option. The guarantor conversation may end with relief on both sides of the table.

One nuance worth knowing: some participating lenders may price Scheme loans competitively, but pricing is lender- and product-specific. And eligible single parents get the 2% floor — our full guide to that stream.

The scheme has its own traps — we’ve seen a build contract land $37,000 over the price cap and void eligibility with finance due the next week, and reservations get stuck between lenders with deposits on the line. The video above covers the eight mistakes we see most; the short version is that scheme eligibility is not loan approval, price caps are hard edges, and the reservation mechanics matter.

When a Guarantor Wins

Four situations, all common:

1. You have less than 5% — or your savings aren’t “genuine.” The scheme needs the required deposit, and the participating lender may apply its own deposit-source or genuine-savings rules. A guarantor may reduce the deposit requirement, and some lenders may fund eligible costs. If you’re at $0–4% saved and rents are eating your saving capacity, this is the classic guarantor case.

2. You’re buying above the price cap. Brisbane’s $1,000,000 cap sounds high until you’re buying a family home in the inner suburbs. Above the cap, the scheme may not be available — a guarantor structure does not use that Government Scheme cap, but lenders still apply their own property, valuation and servicing limits.

3. You’re buying an investment property. The scheme is owner-occupier only. A small number of lenders will support investment purchases with a guarantor — with extra care, because the guarantor carries risk while you take the returns. We’re direct with families about that trade-off.

4. You’ve owned property before and don’t fit the scheme’s criteria. The scheme’s rules around prior ownership and circumstances don’t fit everyone — post-separation buyers re-entering the market being the big group. (Eligible single parents should check the 2% stream first; guarantor support is often the fallback. Some lenders are less conservative than others about second-time buyers with guarantors — this is a lender-selection question.)

The scheme wins on family risk. The guarantor may offer flexibility beyond the Scheme’s location caps, but lenders still apply their own property, valuation, LVR and owner-occupier rule, and a true $0-deposit path.

The Third Option Nobody Prices: Both Generations, Different Tools

Sometimes the best structure isn’t scheme-or-guarantor — it’s a gift(which can make your 5% appear, though gifted money usually needs three months’ seasoning to count as genuine savings, or the right lender), a co-borrower, or a property-share arrangement. If your parents are weighing “go guarantor or just give them the money,” that exact comparison — including what it does to LMI, genuine savings and everyone’s risk — is its own guide. And if the myth that a guarantor boosts borrowing power is doing the heavy lifting in your family’s thinking, read the honest answer first.

This is the exact comparison we build for clients in a free assessment: your borrowing power, then the purchase you could make under the scheme versus with a guarantor, in dollars, side by side — deposit required, costs covered, LMI saved, and who carries what risk. Twenty minutes of numbers usually makes the decision obvious in one direction or the other.
