Market insight
Lenders are competing aggressively for refinance business in 2026. Many are offering cashback incentives of $2,000 to $4,000 and fee waivers that are not available to new purchase borrowers. If you have not reviewed your home loan in the past 12 months, there is a strong chance you are paying more than you need to.
Market update
Investment property loan rates have increased alongside owner-occupier rates, but the gap between the two has narrowed in recent months as lenders compete for investment lending. The current best investment property loan rate on our database starts from 5.20% p.a., with most competitive rates sitting in the mid-to-high 5% range.
Rental yields in many Australian capital cities have strengthened as population growth outpaces housing supply. This has improved the serviceability calculations for investment property borrowers, as lenders factor rental income into their assessment of your ability to service the loan. Investors with strong rental yields may find they can borrow more than expected.
Tax considerations remain a key factor for investment property borrowers. Negative gearing, depreciation deductions, and the structure of your investment property loan (interest-only versus principal and interest) all affect your after-tax return. A specialist investment broker understands these factors and can help you structure your loan to maximise your investment outcome.

Guide
An investment property loan is a mortgage used to purchase a property that you intend to rent out or hold as an investment rather than live in as your primary residence. Investment property loans typically carry slightly higher interest rates than owner-occupier loans because lenders consider them higher risk.
Investment property loans come in two main repayment types: principal and interest (P&I) where you pay down the loan balance over time, and interest-only (IO) where you only pay the interest for a set period (usually 1-5 years). Interest-only loans result in lower repayments but do not reduce your loan balance, which can be a deliberate strategy for investors focused on cash flow and tax deductions.
The amount you can borrow for an investment property depends on your income, existing debts, the expected rental income from the property, and your deposit. Most lenders require a minimum 10-20% deposit for investment properties, and some charge higher rates for loans with a loan-to-value ratio above 80%.
Choosing between interest-only and principal and interest repayments is one of the most important decisions for investment property borrowers. Interest-only loans offer lower monthly repayments, which improves cash flow and maximises the tax-deductible portion of your loan. However, you are not building equity through repayments.
Principal and interest loans cost more each month but reduce your loan balance over time, building equity in your investment property. This can be advantageous if you plan to hold the property long-term or want to use the equity to fund future investment property purchases.
Many investment property borrowers start with an interest-only period and then switch to principal and interest after a few years. Your investment broker can model both scenarios and help you understand the cash flow and tax implications of each approach for your specific situation.
Investment property borrowers in Australia can claim several tax deductions that reduce the effective cost of their loan. The interest on your investment property loan is tax-deductible, which means the after-tax cost of your loan is lower than the headline rate. For a borrower in the 37% tax bracket, a 6% investment loan effectively costs around 3.78% after the tax deduction.
Negative gearing occurs when the costs of owning your investment property (including loan interest, maintenance, insurance, and depreciation) exceed the rental income. The resulting loss can be offset against your other income, reducing your overall tax bill. This is a key reason why many investors choose interest-only loans to maximise deductible expenses.
Depreciation is another significant tax benefit for investment property owners. You can claim deductions for the decline in value of the building structure and the fixtures and fittings within it. A quantity surveyor can prepare a depreciation schedule that typically identifies $5,000 to $15,000 in deductions per year for a new or near-new investment property.

Frequently asked questions
Answers to the most common questions about investment property in Australia.
Most lenders require a minimum 10-20% deposit for an investment property loan. A 20% deposit avoids Lenders Mortgage Insurance and typically qualifies you for better interest rates. Some lenders accept lower deposits for investment properties, but the rates and fees are usually higher.
Yes, using equity from your existing home is one of the most common ways to fund an investment property deposit. Your broker can assess your available equity and help you structure the loan to minimise risk while maximising your investment capacity.
Interest-only loans offer lower repayments and maximise tax deductions, while principal and interest loans build equity over time. The best choice depends on your investment strategy, cash flow needs, and tax situation. Your investment broker can model both scenarios for your specific circumstances.
Negative gearing occurs when the costs of owning your investment property exceed the rental income. The resulting loss can be offset against your other income, reducing your tax bill. It is a common strategy for investment property owners in Australia, particularly those on higher marginal tax rates.
Lenders typically factor 80% of expected rental income into their serviceability assessment. This means a property with strong rental yield can increase your borrowing capacity. Your broker can help you understand how rental income from your investment property affects how much you can borrow.
Yes, investment property loan rates are typically 0.2% to 0.5% higher than equivalent owner-occupier rates. This is because lenders consider investment loans slightly higher risk. However, the tax deductibility of investment loan interest means the after-tax cost difference is smaller than the headline gap.
Cross-collateralisation is when a lender uses multiple properties as security for your loans. While it can simplify borrowing, it also gives the lender more control over your portfolio. Most investment brokers recommend keeping each property with a separate security structure to maintain flexibility.
Yes, many investors purchase investment property through a company, trust, or self-managed super fund (SMSF). Each structure has different tax implications, asset protection benefits, and lending requirements. Your broker can explain how each structure affects your investment property loan options.
There is no fixed limit on the number of investment properties you can finance, but your borrowing capacity will eventually be constrained by your income, existing debts, and the rental yields of your portfolio. Some lenders have internal limits on the number of investment properties they will lend against.
Comparing investment property loan rates through OptiCheck does not affect your credit score. Our SmartCheck is a soft enquiry that helps assess your borrowing capacity without leaving a mark on your credit file. A formal credit check only occurs when you submit a full application.
