Property Investment Loans Australia
Structuring, tax efficiency and lender selection for your next investment purchase
Whether you are buying your first investment property or adding to an existing portfolio, the way your loan is structured can make or break your returns. Rovo Finance specialises in investment property lending. We compare products across 40+ lenders, model different structuring scenarios, and help you maximise borrowing capacity and tax efficiency from day one.
What is an investment property loan?
An investment property loan is a home loan used to purchase a property you do not intend to live in. The property is held as an investment, typically to generate rental income and long-term capital growth.
Investment loans work differently from owner-occupier loans in several important ways:
- Higher interest rates – investment loans typically attract rates 0.2 to 0.5% higher than owner-occupier rates because lenders consider them slightly higher risk
- Different tax treatment – the interest on your investment loan is tax-deductible, and you may be able to claim depreciation on the property itself
- Interest-only repayment options – many investors choose interest-only periods (typically 1 to 5 years) to maximise cash flow and tax deductions during the accumulation phase
- Stricter serviceability assessment – lenders assess your ability to repay at a higher buffer rate and factor in existing debts across your entire portfolio
- LVR requirements – most lenders allow up to 80% LVR for investment properties without LMI, though some products allow up to 90% with LMI
Interest only vs principal and interest investment loans
This is one of the most important structuring decisions for property investors. Here is how the two options compare:
| Interest Only (IO) | Principal and Interest (P&I) | |
|---|---|---|
| What you pay | Interest charges only, the loan balance does not reduce | Interest plus a portion of the principal, gradually paying off the loan |
| Monthly repayments | Lower during the IO period | Higher from day one |
| Cash flow impact | More cash available for other investments or expenses | Less free cash but you build equity faster |
| Tax deductions | Maximum deductible interest (loan balance stays high) | Deductible interest decreases over time as balance reduces |
| Typical IO period | 1 to 5 years, then reverts to P&I | N/A |
| Interest rate | Usually 0.1 to 0.3% higher than P&I | Slightly lower |
| Suited to | Investors prioritising cash flow and tax deductions | Investors focused on long-term equity building |
There is no universally correct answer. The right choice depends on your investment strategy, tax position, and how many properties you plan to hold. We model both scenarios so you can see the numbers side by side before deciding.
Negative gearing, positive gearing, and tax implications
Understanding how your investment property interacts with the tax system is essential to structuring your loan correctly.
Negative gearing occurs when your property’s expenses (loan interest, maintenance, management fees, insurance, depreciation) exceed the rental income. The resulting loss can be offset against your other income, reducing your taxable income. This is one of the main reasons investors choose interest-only loans during the early years of ownership.
Positive gearing occurs when rental income exceeds all property expenses. The profit is added to your taxable income. This is more common for investors with significant equity or properties in high-yield areas.
Tax-deductible expenses for investment property owners in Australia include: loan interest, property management fees, council rates, insurance, repairs and maintenance, depreciation of the building and fittings, and travel to inspect the property (within ATO limits). We are not tax advisers, but we structure your loan so your accountant has the flexibility to optimise your tax position.
Important: Tax laws change. Always consult a qualified accountant or tax adviser for advice specific to your situation.
How to use equity to buy your next investment property
If you already own a home or another investment property, you may be able to use the equity in that property as a deposit for your next purchase, without needing to save additional cash.
Equity is the difference between your property’s current market value and the amount you still owe on the mortgage. For example, if your home is worth $800,000 and you owe $400,000, you have $400,000 in equity. Most lenders will let you access up to 80% of your property’s value, minus the outstanding loan. In this example, that would be $640,000 minus $400,000 = $240,000 in usable equity.
This usable equity can serve as the deposit and costs for your next investment purchase without you touching your savings account. We help you calculate your available equity, identify which lenders offer the most favourable terms for equity release, and structure the borrowing across your portfolio to keep things clean for tax purposes.
Cross-collateralisation: what it is and why it matters
Cross-collateralisation is when a lender uses more than one of your properties as security for a single loan. Some banks do this by default when you borrow for a second or third property through the same institution.
This can create problems:
- If you sell one property, the lender may reassess your entire portfolio and potentially require you to pay down debt on the remaining properties
- It makes refinancing individual properties more difficult because the lender has a claim over multiple assets
- It reduces your flexibility to move properties between lenders to chase better rates
Rovo Finance typically structures investment loans as standalone securities where each property secures only its own loan. This gives you maximum flexibility to sell, refinance, or restructure individual properties without affecting the rest of your portfolio.
How Rovo Finance helps property investors – step by step
1. Free strategy call – We assess your current portfolio, borrowing capacity, equity position, and investment goals. We tell you honestly how much you can borrow and what structure makes sense.
2. Structuring advice – We model different scenarios: interest-only vs P&I, fixed vs variable, standalone vs cross-collateralised, and show you how each option affects your cash flow, tax position, and borrowing capacity for future purchases.
3. Lender comparison – We compare investment products across 40+ lenders, factoring in rates, policies, turnaround times, and how each lender assesses rental income and existing debt.
4. Application and approval – We prepare and submit the application, handle valuation queries, and keep things moving. For investors with multiple properties, we ensure the application accounts for your full portfolio correctly.
5. Settlement – We coordinate with your conveyancer and the lender to settle on time.
6. Portfolio reviews – We stay in touch for annual rate reviews, refinancing opportunities, equity assessments, and support for your next acquisition.
Common mistakes property investors make
Cross-collateralising without realising. If you go to the same bank for every property, they may link all your securities together by default. This limits your future options. We structure loans to keep properties independent.
Choosing the lowest rate without checking serviceability policy. Different lenders calculate your borrowing power differently. A lender with a slightly higher rate might approve you for $100,000 more because of how they treat rental income or existing debt. We compare the full picture, not just the headline rate.
Not stress-testing cash flow. What happens to your repayments if rates rise 2%? What if the property is vacant for 6 weeks? We model these scenarios before you commit so you know your worst-case position.
Ignoring loan structure for tax purposes. Mixing investment and personal borrowing in the same loan (or using an offset account incorrectly) can create tax complications that cost you more than the interest savings. We help you keep things clean from the start.
Waiting too long to get pre-approved. In competitive markets, missing a property because your finance was not in order is one of the most expensive mistakes an investor can make.
