Home Loans in Australia: Every Type Explained

There are roughly a dozen home loan types in Australia, and the right one depends less on the product and more on your situation. Variable, fixed, split, interest-only, offset, low-doc, construction, bridging, guarantor, SMSF, reverse mortgage. Same shopfront, different tools. In the June Quarter of 2026, the ABS recorded 134,225 new loan commitments for dwellings across the country, and almost every one of those borrowers had to make the same handful of choices you're about to make.

This page groups loans by who you are and what you're trying to do. Short honest read on each, then a link to the deeper page if you want more.

Strip away the marketing and every home loan comes down to two decisions.

How your interest rate behaves: variable, fixed, or a split of both.
How you repay: principal and interest, or interest-only.

Everything else (offset accounts, redraw, portability, low-doc, guarantor structures) is either a feature bolted onto those two choices or a variation built for a specific borrower. To give you a sense of the market right now, in June 2026 the RBA had new owner-occupier principal-and-interest loans averaging 6.17% p.a. and new owner-occupier interest-only loans averaging 6.98% p.a. The averages show interest-only loans were priced higher that month, although borrower, product and LVR differences may also affect the gap.

Your rate moves with the market. When the RBA cuts, your rate usually falls. When it lifts, it rises. Variable loans commonly allow extra repayments and may offer redraw or an offset account, depending on the product. Most Australians pick variable, and the market agrees. The RBA's May 2026 Bulletin reported the share of outstanding housing loans on fixed rates fell to a historical low of under 5% in 2025.

You lock the rate for one to five years. Certainty is the upside. The downside is restriction. Extra repayments are usually capped, offset accounts are often unavailable or partial, and breaking the fix early can trigger break costs that hurt.

Half fixed, half variable, in whatever ratio you choose. A split loan gives you predictable repayments on part of the balance while keeping the remainder flexible. The trade-off is having two loan portions that may come with different features and restrictions.

If you want the full breakdown of the trade-offs, read fixed versus variable in more detail.

Principal and interest (P&I) is the default. Each repayment chips away at both the interest and the loan balance. You end up owning the place.

Interest-only (IO) means for a set period, usually one to five years, you only pay the interest. Your balance doesn't move. Repayments are lower during that window, then jump when the loan reverts to P&I.

IO is commonly used by investors to manage cash flow. Interest may be deductible when the borrowed funds are used to produce assessable income, subject to the tax rules. It comes at a price. In June 2026 the gap between new owner-occupier P&I and IO rates was about 0.81%. That premium adds up. Most owner-occupiers are better off on P&I. If you're investing, read interest-only for investment property before you commit.

The useful shortlist usually becomes clear once you look at what you're buying, how you earn and how much flexibility you need.

You don't always need a 20% deposit. In a lot of cases, 5% is enough. Between Lenders Mortgage Insurance, a family guarantor, and the various federal and state schemes, first home buyers now have more paths in than they did five years ago. The ABS recorded 29,319 owner-occupier first home buyer commitments in the June Quarter of 2026, so plenty of people are finding a way through.

A family member, usually a parent, uses equity in their property as extra security for part of your loan. Depending on lender policy, this may allow borrowing up to 100% and avoiding LMI. The guarantor's exposure is limited to the guaranteed portion and may be released following lender approval once the required equity and repayment conditions are met. The guarantor becomes legally responsible for the guaranteed portion if you cannot pay, so everyone involved should understand the exposure and obtain independent legal advice before proceeding.

Investors pay a small premium over owner-occupiers. In June 2026, new investor P&I loans averaged 6.32% p.a. against 6.17% for owner-occupiers. Investor lending is still a big chunk of the market, with $37.1 billion in new investor commitments in the June Quarter of 2026 alone. Interest-only is common for investors chasing negative gearing and cashflow. Whether that’s right depends on your tax position, cash flow, investment strategy and capacity to handle higher repayments later.

If you're a sole trader, contractor or business owner, standard payslip-based assessment doesn't fit. Low-doc and alt-doc loans let you evidence income with BAS statements, business bank records, or an accountant's letter. Banks sometimes tighten their assessment of self-employed income when rates fall, even while reducing rates for lower-risk borrowers. A broker who regularly handles self-employed home loans will know which lenders are applying more workable income policies.

A construction loan releases funds in progress payments as your build hits each stage: slab, frame, lockup, fixing, completion. You pay interest only on the drawn portion during the build, then it converts to P&I once the property is finished. Valuations happen at each stage. If you're renovating an existing home rather than building your own home from scratch, the structure is similar but often runs through a refinance.

You buy the next home before you've sold the current one. The lender extends short-term credit against both properties, known as peak debt, and once the old place sells the proceeds pay down the bridge. Terms are usually six to twelve months. Expensive if the sale drags, cheap peace of mind if it doesn't.

For retirees who own their home and want to draw on that equity without moving. You borrow against the property, make no repayments while you live there, and the interest compounds onto the balance. Australian reverse mortgages carry a statutory no-negative-equity guarantee, so you can never owe more than the house is worth. Whether it makes sense depends on your age, how much equity you use and whether preserving the estate matters to you. Get financial advice before signing.

SMSF loans let a self-managed super fund borrow to buy property through a limited recourse borrowing arrangement. The rules are strict and the lender pool is small. Non-conforming loans sit outside standard bank criteria, usually for credit-impaired borrowers, unusual income, or property types major lenders won't touch. Both are specialist products where lending, legal and tax advice may be valuable.

In a falling-rate environment, the most common mistake is chasing the headline rate and ignoring the structure of the loan. The structure is often worth more.

Offset account. A transaction account linked to your loan. With a 100% offset account, every dollar sitting in it reduces the balance used to calculate interest. Australians now hold about $349.1 billion in mortgage offset accounts, up 28% over two years, according to ASIC's July 2026 offset review. ASIC also flagged over $55 million in compensation paid by banks for offset failures between 2023 and 2025. It pays to check yours is actually working. Read how an offset account works for the mechanics.

Redraw facility. Extra repayments you can pull back if you need to. The RBA's May 2026 Bulletin reported around 80% of housing loans now have one.

Extra repayments. Standard on variable loans, usually capped or blocked on fixed.

Portability. Take the loan with you to the next property without refinancing from scratch.

If your bank lowers the minimum repayment after a rate cut, consider leaving your payment unchanged. The difference will go towards the principal and could shorten the life of the loan.

The comparison rate is meant to bundle the headline rate with standard fees so you can compare loans fairly. It's useful, but it's calculated on a $150,000 loan over 25 years. If your loan looks nothing like that, the comparison rate isn't telling you the full story.

• When you're comparing, look at:
• Application, valuation, ongoing and discharge fees
• Break costs on fixed loans
• Whether the offset is genuine or partial
• Cashback offers versus long-term rate

Refinancing has its own maths. A rate cut can trigger a rush to switch, but exit fees, application charges and valuations can quietly erode the saving. Run a break-even analysis. Work out how long it takes to recover the switching costs, and only move if you plan to stay in the loan long enough to benefit. If you're thinking about it, start with refinancing your home loan.
