Interest-only investment loans in Australia

Want the best investment loan rates on an interest-only structure? The honest answer is that there is no single best rate. The right interest-only investment loan depends on your LVR, your servicing position, the security property, and how long you need the interest-only period to run. Windsor Finance is a finance broker. We take your investment lending to a panel of bank and non-bank lenders and place it with the one that fits the deal, then show you the indicative numbers so you can compare like for like.

On prime residential investment lending, indicative pricing currently sits around 6% to 8% per annum. Alt-doc files and complex ownership structures price higher. Those are indicative ranges only. The lender confirms the final rate on application once it has seen the security and your full position.

This page sits under our main investment property loans hub. Interest-only is one structure within investment lending, start here if you want to know how it changes cash flow, equity, and borrowing capacity before you commit.

What an interest-only investment loan actually does. With an interest-only loan you pay only the interest for an agreed period. The principal does not reduce during that window. Your repayments are lower while interest-only runs, which lifts short-term cash flow on the property. This suits investors for a few reasons. Lower outgoings improve the holding cost on a rental. Interest on an investment loan is generally deductible against rental income, so many investors prefer to keep the principal intact rather than pay it down. And keeping cash free can mean the difference between holding one property and funding the deposit on the next. The trade-off is real. You are not building equity through repayments during the interest-only term. When the period ends, the loan reverts to principal and interest over the remaining term, and repayments step up. Plan for that reversion before you sign, not after.

Interest-only periods and how lenders treat them. Most lenders offer interest-only periods of one to five years on investment lending, with some allowing longer terms or renewals subject to a fresh assessment. The period is a feature you negotiate, not a fixed rule. Investor lending attracts tighter serviceability buffers than owner-occupier lending. Lenders assess you on the higher principal-and-interest repayment that applies after the interest-only period ends, not on the lower interest-only repayment you pay today. This matters. A borrower who services comfortably on the interest-only figure can still fall short on the lender’s assessment rate. Different lenders apply different buffers and assessment rates, which is exactly why a panel matters. One lender’s decline is another lender’s approval.

LVR limits on interest-only investment lending. Indicative LVR on standard residential investment lending runs up to around 80%. Above 80%, Lenders Mortgage Insurance generally applies, which adds cost. Commercial and specialised security carries lower LVR limits. Many lenders cap the LVR more tightly when the loan is interest-only than when it is principal-and-interest. If you are pushing toward the upper LVR band and want interest-only, expect fewer lenders in play and slightly firmer pricing. A lower LVR opens the door to better indicative rates and a wider lender choice. This is one of the clearest levers you control on the deal.

Fixed, variable, or split. Variable interest-only gives you flexibility on extra repayments and refinancing, with rate movement risk. Fixed interest-only locks the rate for a set term, which helps cash-flow certainty on a rental but limits flexibility and can carry break costs if you exit early. A split structure puts part of the loan on each. There is no universally correct choice. An investor planning to sell or refinance inside two years weighs flexibility differently from one holding for the long term. Windsor frames both paths against your actual exit before you commit.

Where Windsor adds value. We hold no own capital and lend nothing ourselves. That is deliberate. Because there is no balance sheet pushing us toward one product, the recommendation follows your deal rather than a lender’s quota. One enquiry reaches banks, near-banks, and non-bank lenders. You see real market choice on rate, LVR, interest-only term, and serviceability appetite instead of whatever a single bank happens to offer. We package the file so the credit team sees a clean, complete case the first time, which avoids the costly cycle of decline and re-shop that can mark your credit file. Investment property lending to individuals can fall under the National Consumer Credit Protection Act, depending on the purpose and structure. Business-purpose and many investment structures sit outside it. We keep that distinction clear and arrange your finance accordingly. Windsor Finance is a finance broker that arranges finance through a panel of bank and non-bank lenders. The purpose of each deal is confirmed in writing before it proceeds. We do not provide tax, credit, or financial advice. Every rate, fee, and LVR on this page is indicative; the lender confirms on application.

What it costs to work with us. Indicative structuring and lender shortlisting cost you nothing. There is no charge to see your options framed and compared. You only proceed when you choose to submit. Every cost is disclosed in writing, up front, before you commit. Lender and third-party costs such as establishment fees, valuation fees, legal costs, and LMI where it applies are paid to the lender or provider, not to Windsor, and we set them out up front.
