What Is Negative Gearing and How Does It Work?

Negative gearing occurs when your rental income falls short of the costs of holding an investment property, creating a taxable loss you can claim against other income.

For property investors in Mill Park, where the median house price sits around $650,000 and rental vacancy remains relatively low, negative gearing represents a deliberate strategy rather than a mistake. When structured correctly through an appropriate investment loan, this approach allows you to reduce your current tax liability while banking on capital growth to deliver returns over time. The calculation depends entirely on your borrowing structure, interest rate type, and how much rental income the property generates relative to all holding costs.

How Negative Gearing Calculations Actually Work

Negative gearing happens when your annual property expenses exceed your annual rental income. The shortfall becomes a deductible loss.

Consider an investor who purchases a three-bedroom house in Mill Park for $650,000 with a 20% deposit, borrowing $520,000. At a variable interest rate, the annual interest on an interest-only loan sits around $28,000. Add to that council rates of approximately $1,800, water charges of $800, property management fees at 7% of rent (around $1,680 based on $480 weekly rent), landlord insurance of $600, and maintenance costs averaging $2,000. Annual rental income at $480 per week totals $24,960. Total expenses reach approximately $34,880, creating a negative position of $9,920 annually. This loss can be claimed against the investor's other taxable income, such as salary.

For someone earning $95,000 annually, that $9,920 loss reduces their taxable income to $85,080. At a marginal tax rate of 32.5% (including the Medicare levy), the tax saving amounts to approximately $3,224. The actual out-of-pocket cost after tax becomes $6,696 annually, or roughly $129 per week. This weekly contribution funds the gap while the property potentially appreciates in value.

Interest-Only Versus Principal and Interest Structures

Most investors pursuing negative gearing choose interest-only loans because they maximise the deductible expense and minimise cash flow pressure.

With an interest-only investment loan, every dollar of interest paid remains tax-deductible. Principal repayments, by contrast, reduce your loan balance but deliver no tax benefit. An interest-only structure on that $520,000 loan keeps monthly repayments at approximately $2,333 (interest only), compared to around $3,150 for principal and interest at similar rates. The difference of $817 monthly matters significantly when you're already funding a shortfall between rent and costs.

Interest-only periods typically run for five years, with the option to extend depending on lender criteria and your borrowing capacity. After the interest-only period ends, the loan reverts to principal and interest unless you refinance. Many investors structure their portfolio to either refinance at that point or use equity from capital growth to adjust their strategy.

What Expenses Can You Claim Under Negative Gearing

Almost all costs associated with earning rental income become claimable expenses when calculating your taxable loss.

Deductible expenses include loan interest, property management fees, council and water rates, landlord insurance, building depreciation, repairs and maintenance, and body corporate fees for units. If you purchase a property in one of Mill Park's newer estates near Redstone Hill or around Westfield Plenty Valley, depreciation schedules on relatively new builds can add several thousand dollars to your annual deductions without requiring any cash outlay.

Stamp duty and Lenders Mortgage Insurance (LMI) are not immediately deductible in full. Instead, they're claimed over five years for stamp duty or the loan term for LMI. Legal and borrowing costs associated with securing the investment loan can be claimed in the year incurred or spread across five years. Rental advertising, pest inspections, and even stationery used for property management all qualify as claimable expenses.

One important limitation applies to capital improvements. Renovations that improve the property beyond its original condition must be depreciated over time rather than claimed immediately. Replacing a broken hot water system is deductible as a repair. Installing a new kitchen where a functional one existed is a capital improvement.

When Negative Gearing Makes Sense for Your Situation

Negative gearing delivers the strongest benefit to investors with taxable income in the higher marginal tax brackets who expect capital growth to outpace the cumulative holding costs.

In areas like Mill Park, where proximity to schools, Westfield Plenty Valley, and the South Morang rail extension has driven steady capital growth, investors often accept short-term cash flow losses in exchange for long-term equity gains. The strategy assumes that when you eventually sell the property, the capital gain will exceed the total out-of-pocket contributions you made over the holding period.

For someone earning $120,000 annually, the tax savings on a $10,000 annual loss reach approximately $3,900 (at a 39% marginal rate including Medicare levy). The actual cost of holding the property becomes $6,100 per year. If the property appreciates by 5% annually on a $650,000 purchase, that's $32,500 in equity per year. After five years, you've contributed $30,500 out of pocket but gained approximately $162,500 in equity growth (compounding), plus whatever principal you've repaid if not on interest-only.

Negative gearing suits investors with stable income, sufficient cash reserves to cover the shortfall, and a timeline of at least seven to ten years. It becomes less effective for lower-income earners where the tax offset is minimal, or where rental yields are so poor that even high tax savings can't make the numbers work.

Fixed Rate Versus Variable Rate on Investment Loans

Variable rates preserve flexibility and typically allow unlimited extra repayments, which matters if your circumstances change or you want to reduce the loan balance strategically.

Fixed rates lock in your interest cost for a set period, which helps with cash flow predictability but limits your ability to make extra repayments without penalty. For negative gearing purposes, variable rates often make more sense because the deduction adjusts naturally as rates move. If rates fall, your deduction shrinks but so does your actual cost. If rates rise, your cost increases but so does your tax offset.

Some investors split their loan between fixed and variable to balance certainty with flexibility. On a $520,000 loan, you might fix $260,000 for three years and leave $260,000 variable. This approach provides some protection against rate increases while maintaining the ability to pay down the variable portion if your income or strategy changes.

Equity and Portfolio Growth Through Leveraged Property

Negative gearing becomes particularly effective when used to build a multi-property portfolio, where equity from one property funds deposits on the next.

After several years of ownership and capital growth, the increased value of your Mill Park investment can be accessed through equity release. If your $650,000 property appreciates to $800,000 and your loan balance sits at $500,000, you hold $300,000 in equity. Most lenders allow you to borrow up to 80% of the property value without incurring LMI on the additional funds. That means you could potentially access up to $140,000 (80% of $800,000 minus the existing $500,000 loan, leaving $640,000 total lending).

This released equity can fund the deposit on a second investment property without requiring you to save cash separately. As long as your income supports the borrowing capacity for multiple properties and the combined negative gearing position remains manageable, this approach accelerates portfolio growth. Each property generates its own negative gearing benefit while contributing to your overall wealth accumulation.

Investors using this model often transition properties from negative to neutral or positive gearing over time as rents increase and loan balances reduce, freeing up serviceability for the next acquisition.
