Interest Only Home Loan Rates, July 2026

Yes, owner-occupiers can get an interest-only home loan, though it's more common with investors. Lenders apply tighter limits to owner-occupier interest-only lending and usually want a clear reason for it, such as a short-term cash-flow need or a renovation period, plus evidence you can afford the higher repayments once the interest-only term ends. The rate is typically a little higher than the equivalent principal-and-interest rate, and you'll generally need a stronger deposit. The table above lets you filter for interest-only loans across both purposes.

Most lenders offer interest-only terms of one to five years at a time, with five years being the common maximum on a single approval. You can sometimes extend by applying again before the term ends, but the lender re-assesses your circumstances each time and total interest-only periods are usually capped, often at around ten years over the life of the loan for investors and less for owner-occupiers. The shorter the interest-only term, the smaller the repayment step-up when it ends.

When the interest-only term ends, the loan reverts to principal-and-interest, and your repayment jumps, sometimes sharply, because you now repay the full balance over the remaining, shorter loan term. On a 30-year loan with a 5-year interest-only period, you repay the principal over 25 years instead of 30, so the increase is more than just adding principal. Plan for it ahead of time: you can refinance, request a new interest-only term, or switch voluntarily to principal-and-interest early to soften the change.

The lowest comparison rate on Ratesniffers as of 28 July 2026 is 6.17%, on a headline variable rate of 5.89%. Advertised owner-occupier variable rates across the major and challenger lenders currently span roughly the high-5% to high-6% range, with investor and interest-only rates sitting higher. Every rate in the table above is refreshed daily.

There is no single bank with the best rate for everyone, the sharpest advertised rates usually come from online-direct lenders and challenger brands rather than the Big Four, but the rate you actually qualify for depends on your deposit (LVR), whether you're owner-occupier or investor, and the loan features you need. The lender at the top of the table above has the lowest comparison rate today; sort and filter to match your situation.

As a rough guide, a competitive owner-occupier variable rate is one at or near the top of this table, currently around a 6.17% comparison rate. Anything materially above that, especially if you have a deposit of 20% or more and a clean credit history, is worth challenging. A "good" rate is always relative to your LVR, loan purpose and the features you need.

The interest rate (or headline rate) is the cost of the loan before fees. The comparison rate folds in most standard upfront and ongoing fees, normalised on a $150,000 loan over 25 years, so two loans with the same headline rate but different fees show different comparison rates. It's a mandatory disclosure under the National Consumer Credit Protection Act 2009, and it's the fairer number to rank loans by, which is exactly how the table above is sorted.

Five levers move your rate the most: a lower LVR (a bigger deposit), choosing owner-occupier over investor where it applies, principal-and-interest over interest-only, a clean credit file, and simply asking. Lenders routinely offer existing customers a discount when they call to leave, and a mortgage broker can run that negotiation across the whole panel at once, which is the service Ratesniffers connects you to for free.

Yes, and you should. Lenders price new customers more sharply than existing ones, so loyalty often costs you. Call your lender's retention team, quote a cheaper comparable rate from the table above, and ask them to match it. If they won't move, refinancing to a lender that will is usually straightforward, and many pay cashback to switch.

Average advertised owner-occupier variable rates sit well above the cheapest rates, because the average is dragged up by lenders who don't compete on price. That's the point of comparing: the gap between the average rate and the lowest rate in the table above is real money. Rather than aim for the average, aim for the top of the table for your situation.

Variable home loan rates track the Reserve Bank's cash rate, so the direction of rates depends on the RBA's decisions, which it reviews roughly every six weeks. We don't make forecasts we can't stand behind, but we do publish a wrap of every RBA decision and what it means for variable-rate borrowers, see our news page. Fixed rates move ahead of the cash rate, based on what the market expects the RBA to do next.

Individual lenders change rates continually, sometimes several times a week, and often within days of an RBA decision or a competitor's move. That's why a comparison table is only useful if it's fresh. Ratesniffers refreshes its rate index daily and stamps every page with the last-updated date so you're never comparing stale numbers.

Variable rates move with the RBA cash rate, so you benefit when rates fall and pay more when they rise; they also tend to come with offset accounts and free extra repayments. Fixed rates lock your repayment for a set term, which buys certainty but usually limits extra repayments and charges break costs if you exit early. Many borrowers split the loan to get some of each, you can filter for fixed, variable or split above.

A deposit of 20% or more (an LVR of 80% or less) gets you the sharpest rates and avoids Lenders Mortgage Insurance, but you can borrow with as little as 5% down. Lower deposits usually mean a slightly higher rate plus LMI, though first home buyers using the federal Home Guarantee Scheme can avoid LMI even with a small deposit. Use the LVR filter above to see only the loans you qualify for.

A broker compares lenders for you, handles the paperwork, and negotiates the rate on your behalf, usually at no cost to you, because the lender pays the broker. The advantage is leverage: a broker knows which lenders are discounting this week and can put your file in front of the one most likely to say yes. Ratesniffers connects you to a broker who works the whole panel; the comparison itself is always free.

Every rate here was last refreshed on 28 July 2026 and is re-checked daily against each lender's own published product pages before it goes live. We stamp the date on the page so you can see exactly how fresh the data is.

Comparing rates and using the calculators is completely free, with no sign-up or email gate. We don't take paid placement to influence the ranking, loans are sorted by comparison rate, full stop. When you choose to speak to a broker about applying, the lender pays the broker a commission, the same way it would for any mortgage. That's how the service stays free to you.
