Positive Gearing: 5 Ways to Turn Rent Into Profit

A positive geared property generates more rental income than it costs to hold each month.

For investors in Mackay and across Queensland, that income covers the mortgage repayment, body corporate fees, insurance and rates, with cash left over. It's an approach that builds wealth without relying on salary top-ups, and it works particularly well in regional centres where rental yields often sit above capital city averages.

How Positive Gearing Works on an Investment Loan

Positive gearing happens when rental income exceeds all holding costs, including interest, rates, insurance and management fees. The surplus is taxable income in your hands each year. Unlike negative gearing, where you claim a loss against other income, positive gearing means you pay tax on the profit. The advantage is cash flow. You're not funding a shortfall from your pay packet, and the property supports itself from settlement.

Consider an investor who purchases a unit in South Mackay at the suburb's current median, with a 20 per cent deposit. Rental yield in that area regularly sits between 5.5 and 6 per cent. With an interest-only investment loan at current variable rates, the monthly interest cost might be covered entirely by rent, leaving a small surplus after outgoings. That surplus compounds when interest rates fall or when the loan transitions to principal and interest repayments with a lower outstanding balance.

Interest-Only Loans and Cash Flow

An interest-only loan keeps your repayments lower in the early years, which improves cash flow and makes positive gearing more achievable. You're not paying down the principal during the interest-only period, so the entire rental income goes toward covering interest and other holding costs. Most lenders offer interest-only terms of up to five years on investment loans, with the option to extend depending on your circumstances and the loan-to-value ratio.

Interest-only lending attracts higher capital requirements under the prudential framework, which flows through to slightly higher interest rates compared to principal and interest loans. The difference is usually between 0.10 and 0.30 percentage points, depending on the lender and your deposit size. That rate gap narrows when your deposit is 30 per cent or more, and some lenders offer identical rates at lower loan-to-value ratios.

Choosing the Right Property for Rental Yield

Rental yield is the annual rent divided by the purchase price, expressed as a percentage. Regional Queensland properties, particularly units in established suburbs close to schools, hospitals and shopping centres, tend to deliver higher yields than capital city equivalents. In Mackay, suburbs like Andergrove, North Mackay and West Mackay attract steady rental demand from working families and hospital staff, with yields often above 5 per cent even at current price levels.

A property with strong rental demand and low vacancy reduces the risk of income gaps. Check the local vacancy rate before committing. Mackay's vacancy rate has remained below 2 per cent for extended periods, supported by mining sector employment and limited new supply. A low vacancy rate means shorter gaps between tenants and more reliable cash flow, which is what makes positive gearing sustainable over time.

Variable Rate or Fixed Rate for Positive Gearing

Most positively geared investors choose a variable rate or a partial fixed rate split. Variable rates move with the market, which means your repayments fall when the Reserve Bank cuts rates. That rate drop flows directly to your cash flow. Fixed rates lock in certainty but remove the benefit of rate cuts during the fixed term, and they typically sit higher than variable rates for investment property finance at the time of writing.

A split rate structure, where part of the loan is fixed and part remains variable, gives you some downside protection if rates rise while preserving access to offset accounts and rate cuts on the variable portion. If you're already positively geared on a variable rate, fixing a portion of the loan can protect that surplus without locking in the entire balance. Just confirm that the lender allows redraws or offsets on the variable portion, as these features help manage surplus cash flow.

Borrowing Capacity and Serviceability

Lenders assess investment loan applications using a higher interest rate buffer than the actual product rate. The Australian Prudential Regulation Authority requires lenders to test your ability to service the loan at least 3 percentage points above the variable rate you'll actually pay. That buffer reduces how much you can borrow compared to an owner-occupier loan, even when rental income is included in the assessment.

Rental income is typically included at 80 per cent of the amount shown on the lease or a rental appraisal, to account for vacancy and management costs. Some lenders apply a lower shading percentage depending on the property type and location. If you're refinancing or purchasing a second investment property, the rental income from your existing property is included in the same way. Positive gearing on your first property improves your borrowing capacity for the next one, because the lender sees surplus income rather than a loss.

Tax on Positive Gearing

When your property is positively geared, the surplus rent is added to your taxable income each year. You still claim deductions for interest, rates, insurance, property management fees, depreciation and other holding costs, but the rental income exceeds those deductions, so you pay tax on the difference. The tax is calculated at your marginal rate, which means higher income earners pay more tax on the surplus than lower income earners.

That tax liability is often offset by the benefit of holding a property that pays for itself. In our experience, investors who prioritise cash flow over tax deductions find positive gearing more sustainable, particularly when interest rates are volatile or when borrowing capacity is needed for portfolio growth. If you're purchasing an eligible new build, the existing negative gearing treatment continues to apply regardless of when you buy, which means you can claim losses against other income if the property isn't immediately positively geared.

Offset Accounts and Surplus Cash

An offset account linked to your investment loan reduces the interest you pay each month, which increases your cash flow. If your loan balance is $400,000 and you hold $20,000 in the offset, you're only charged interest on $380,000. The rental income stays the same, but your interest cost falls, so the surplus grows. Offset accounts are usually only available on variable rate loans, not fixed, and some lenders charge a higher rate or annual fee for loans with offset features.

If your property is already positively geared, the surplus cash can go into the offset account, which compounds the benefit. You're not paying down the principal on an interest-only loan, so the offset becomes the mechanism for reducing your effective interest cost over time. That structure keeps your equity accessible while still improving cash flow, and it works particularly well when you're planning to purchase additional properties in the future.

Accessing Investment Loan Options Across Multiple Lenders

Different lenders assess rental income differently, apply different LVR caps for interest-only lending, and offer different rate discounts depending on your deposit size and the property type. A broker can access investment loan options from banks and lenders across Australia, compare the rental income shading each lender applies, and structure the application to maximise your borrowing capacity and cash flow.

Some lenders are more comfortable with regional Queensland property than others, and some apply postcode-specific lending restrictions that aren't published on rate sheets. We regularly see investors knocked back by one lender and approved by another with better terms, purely because the second lender's serviceability model treats Mackay rental income at a higher shading percentage. A loan health check before you start looking at properties can show you exactly how much you can borrow and which lenders will give you the most flexibility.
