Why Positive Gearing Matters for Sydney Investors

A positively geared investment property produces more rental income than it costs to hold each week, which means the property pays you rather than drawing from your salary.

This used to be rare when interest rates sat near record lows and property prices climbed fast enough to justify a loss for the sake of capital growth. Things have shifted. Rental yields in parts of Greater Sydney now sit between 4.5 and 5.5 per cent on units and townhouses, while borrowing costs have stabilised. The combination makes positive gearing achievable for investors who know how to structure the loan and choose the right property type.

From July 2027, new legislation will quarantine rental losses on established properties purchased after 12 May 2026, which removes the ability to offset those losses against your salary. That change doesn't affect positive cash flow properties because there's no loss to quarantine. If your property generates surplus income each month, the new rules don't touch you. That's one reason investors are rethinking the old assumption that negative gearing is the default.

How Positive Cash Flow Changes Your Borrowing Position

When a property generates surplus income, lenders treat the rental differently. Negative cash flow properties reduce your borrowing capacity because the loss has to be funded from your salary. A positively geared property adds to your serviceability because the surplus rental income offsets the expense.

Consider an investor purchasing a two-bedroom unit in Liverpool that rents for $620 per week. The purchase price sits at $550,000. With a 20 per cent deposit, the loan amount is $440,000. On a variable rate at 6.30 per cent over a 30-year principal and interest term, the repayment is around $2,725 per month. Add strata fees at $1,100 per quarter, insurance at $800 per year, council rates at $1,400 per year, and property management at 7 per cent of rent. Total monthly holding cost comes to around $3,165. Monthly rental income at $620 per week is roughly $2,685. The property runs a small deficit of $480 per month before tax deductions.

Switch the loan structure to interest-only for the first five years, and the monthly repayment drops to around $2,310. Now the monthly holding cost is approximately $2,750. The property moves into positive territory by around $65 per month before tax. That's not a windfall, but it's also not a drain. And once you factor in deductions for interest, depreciation, and other claimable expenses, the after-tax position improves further. The rental income now supports the holding cost instead of competing with it.

Interest-Only Terms and Why They Suit Positive Gearing

Interest-only repayments reduce your monthly outgoing, which widens the gap between rent and cost. Most lenders offer interest-only periods of up to five years on investment loans, with the option to extend or revert to principal and interest after that.

The trade-off is that you're not paying down the loan balance during the interest-only period, so your equity position only grows if the property value rises or you make voluntary payments. For investors targeting cash flow rather than rapid debt reduction, that trade-off makes sense. You preserve capital, improve monthly surplus, and retain flexibility to deploy savings into other investments or a second property.

Lenders assess interest-only applications on the same serviceability buffer as principal and interest loans, which is currently three percentage points above the product rate. They also calculate the loan as though it will revert to principal and interest at the end of the interest-only term. That means you still need to prove you can service the loan on a fully amortising basis, even if you're only paying interest for the first few years.

Which Property Types Deliver Positive Cash Flow in Greater Sydney

Units and townhouses in established transport corridors offer stronger rental yields than detached houses in the same suburb. A two-bedroom unit near Leppington Station or within walking distance of Liverpool's CBD typically rents for 5 to 5.5 per cent gross yield. Houses in the same postcodes deliver closer to 3.5 to 4 per cent because the purchase price is higher relative to the weekly rent.

Precincts with higher concentrations of renters, such as Edmondson Park and Carnes Hill, show stronger demand for medium-density stock. Vacancy rates in these areas sit below the Greater Sydney average, which reduces the risk of extended periods without rental income. Investors chasing positive gearing need consistent occupancy, so low vacancy is as important as high yield.

New builds and near-new stock also suit this strategy because depreciation schedules are higher in the early years of ownership. A property completed within the last three years can generate $8,000 to $12,000 in annual depreciation deductions, which offsets taxable rental income and improves after-tax cash flow. Older properties still allow depreciation on plant and equipment, but the deductions are smaller.

How Loan Structure Affects After-Tax Returns

Your after-tax position depends on your marginal tax rate and the claimable expenses attached to the property. If you're in the 37 per cent bracket, every dollar of deductible interest saves you 37 cents in tax. On a $440,000 loan at 6.30 per cent interest-only, annual interest is around $27,700. That deduction is worth roughly $10,250 in tax saved.

Add depreciation, property management fees, insurance, council and water rates, strata fees, and repairs. Total deductions on a near-new unit can reach $35,000 to $40,000 in the first few years. Even if the property breaks even before tax, the deductions push the after-tax return into positive territory by several thousand dollars per year.

Investors sometimes overlook body corporate fees when calculating cash flow. In precincts like Edmondson Park, quarterly strata levies on townhouses can range from $800 to $1,400 depending on the development's facilities and age. That's $3,200 to $5,600 per year, and it's a fixed cost whether the property is tenanted or vacant. High strata fees erode cash flow faster than almost any other holding cost, so confirm the levy before you commit.

Why This Strategy Suits Portfolio Growth

Positive cash flow properties don't tie up your surplus income, which means you can save for a second deposit faster. If you're holding two or three properties and each one generates a small monthly surplus, the combined income accelerates your ability to refinance or leverage equity into the next purchase.

Lenders also assess your overall debt servicing position when you apply for a second or third investment loan. If your existing properties show positive cash flow, they strengthen your application rather than weaken it. Negative cash flow properties do the opposite because each one reduces the surplus income available to service new debt.

Under the debt-to-income caps introduced in February 2026, lenders can only allocate 20 per cent of new investor lending to borrowers with a DTI above six times gross income. If you're already carrying negatively geared properties and applying for another loan, you're more likely to hit that cap. Positively geared properties keep your DTI lower and preserve borrowing capacity for future acquisitions.

Variable or Fixed Rates for Positive Gearing

Variable rates give you flexibility to make extra repayments, redraw funds, and switch to principal and interest or interest-only without break costs. Fixed rates lock in your repayment for one to five years, which protects cash flow if rates rise but removes flexibility if you want to restructure or sell early.

Most investors targeting positive cash flow prefer variable rates because the cash flow buffer is thin and the ability to adjust repayments or access equity quickly matters more than rate certainty. If rental income increases or you receive a windfall, you can pay down the loan or offset the balance without penalty. Fixed rates don't allow that.

Some investors split the loan, fixing a portion to protect against rate rises and leaving the rest variable for flexibility. That approach works if you're holding the property long term and want to smooth out repayment fluctuations without giving up all control.

What to Ask Before You Commit

Confirm the rental appraisal with two property managers in the suburb, not just the selling agent. Inflated rent estimates collapse your cash flow model the moment a tenant moves in at the real market rate. Vacancy rates matter just as much. A suburb with a 2 per cent vacancy rate can sustain higher rents than one sitting at 4 per cent.

Check whether the lender will capitalise Lenders Mortgage Insurance if your deposit is below 20 per cent. Capitalising LMI increases your loan amount and reduces cash flow because you're paying interest on a larger balance. If possible, save the full 20 per cent deposit or use equity from another property to avoid LMI altogether.

Ask your broker whether the lender applies a discount or loading to rental income in their serviceability calculation. Some lenders shade rental income by 20 per cent to account for vacancy and maintenance. Others accept 100 per cent of the appraised rent if you provide a signed lease. That difference affects how much you can borrow and whether the deal stacks up.

If you're considering a refinance to improve your rate or access equity, run the numbers on both interest-only and principal and interest terms. Switching from principal and interest to interest-only on an existing loan can flip a negatively geared property into positive territory without changing anything else about the investment.
