Why Positive Gearing Should Guide Your Investment Loan

Positive gearing means your rental income exceeds all holding costs, including loan repayments, rates, insurance, and body corporate fees.

Most discussion around property investment assumes negative gearing is the default position. That approach may have worked under previous tax settings, but the Treasury Laws Amendment (Tax Reform No. 1) Act 2026 changes the calculation for properties acquired after 7:30pm on 12 May 2026. From 1 July 2027, net rental losses on established residential dwellings purchased after that date can no longer be offset against wage income. Losses will only offset other residential rental income or be carried forward. Darwin's rental conditions and price points make it one of the few capital city markets where positive gearing remains achievable without relying on unusually high yields or unsustainably low purchase prices.

Darwin Yields and Loan Structures That Produce Weekly Surplus

Darwin's rental market delivers yields that rarely appear in southern capitals. The city's median gross yield sits above 5 per cent, and units in suburbs closer to the CBD, Larrakeyah, and parts of Parap frequently return higher again. When rental income is strong relative to purchase price, the investment loan structure determines whether that yield translates into positive cash flow.

Consider a unit purchased at the current median where rental income is $650 per week. With a 20 per cent deposit, the loan amount sits below $300,000. At current variable rates, a principal and interest loan on that amount produces repayments around $550 per week, depending on the lender and rate discount. Add $80 per week for rates, insurance, body corporate, and minor maintenance provisions, and total holding costs sit near $630. That leaves a small weekly surplus before tax. Switching to an interest only loan reduces repayments to roughly $430 per week, widening the surplus to $140. The structure doesn't change the rental income or the purchase price, but it determines whether the property costs you money or pays you money each fortnight.

How Legislative Changes from July 2027 Alter the Case for Negative Gearing

Under previous tax settings, a negatively geared property producing a $10,000 annual loss could offset that amount against salary income, reducing taxable income and delivering a refund for higher income earners. From 1 July 2027, properties acquired after 12 May 2026 no longer permit this. Losses are quarantined and can only offset future residential rental income or capital gains on sale. If you hold a single negatively geared property and have no other rental income, those losses accumulate without providing any current-year tax benefit.

Properties held before 7:30pm on 12 May 2026 remain grandfathered under the old rules until sold. Properties purchased between that date and 30 June 2027 receive transitional treatment, allowing negative gearing until 30 June 2027 only. For Darwin investors acquiring property now, the legislation makes positive gearing materially more attractive. A positively geared property delivers surplus income immediately and avoids the need to carry forward losses that may take years to offset.

Interest Only Repayments and Weekly Cash Flow

Interest only repayments reduce the weekly cost of holding an investment property by deferring principal reduction. Over a five-year interest only period, the loan balance remains unchanged, but the lower repayment creates space for rental income to exceed total costs. This structure suits investors prioritising immediate cash flow or planning to use surplus income to offset other debts or fund additional property portfolio acquisitions.

In a scenario where rental income is $620 per week and principal and interest repayments would be $540, total holding costs including rates and insurance might sit at $630. The property loses $10 per week. Switching to interest only reduces repayments to $410, bringing total costs to $500 and creating a $120 weekly surplus. The strategy works when rental income is strong but the loan amount relative to price is high enough that principal and interest repayments push the property into negative territory.

Interest only periods typically run for one to five years, after which the loan reverts to principal and interest unless extended. Lenders assess serviceability on a principal and interest basis at application, so approval for interest only does not mean the property fails to service under full repayments. It means you have the option to hold costs lower while rental income establishes or while you build cash reserves.

Investment Loan Features That Support Positive Gearing Outcomes

Not all investment loan products are structured to support positive gearing. Loan features that allow flexibility without increasing costs include offset accounts, redraw facilities, and the ability to switch between interest only and principal and interest without refinancing. An offset account linked to your investment loan reduces the interest charged each month without formally reducing the loan balance, which preserves deductibility while lowering repayments. Redraw allows access to any additional repayments made above the minimum, creating a buffer without locking funds into the property.

Some lenders charge higher rates for interest only investment loans or apply different rate discounts depending on loan size and loan to value ratio. A borrower with a 20 per cent deposit may access a lower rate than one with a 10 per cent deposit, even on the same product. That rate difference directly affects whether rental income exceeds repayments. We regularly see scenarios where an investor assumes they need a larger deposit to achieve positive gearing, when the actual issue is rate pricing or product selection.

Darwin Vacancy Rates and Rental Income Reliability

Vacancy rate affects whether positive gearing remains sustainable over a full financial year. Darwin's rental vacancy rate fluctuates with employment cycles, defence postings, and major project activity, but it has remained below 2 per cent for extended periods in recent years. Low vacancy improves the reliability of rental income and reduces the risk of holding costs exceeding income during tenant turnover.

A property that produces a $100 weekly surplus when tenanted still incurs holding costs during vacancy. If vacancy averages two weeks per year, that surplus reduces by $200 annually, but the property remains positively geared. If vacancy extends to six weeks, the gap narrows. Darwin's tight rental market reduces this risk compared to markets where vacancy sits above 3 per cent and tenant turnover is more frequent. When structuring an investment property finance arrangement, we factor in realistic vacancy assumptions based on suburb and property type, not best-case occupancy.

Borrowing Capacity and Loan Amount Under Serviceability Settings

APRA requires lenders to assess serviceability at a buffer of 3 percentage points above the product rate. For an investment loan at a variable rate around 6.5 per cent, serviceability is tested at 9.5 per cent. Lenders also apply a rental income shading factor, typically 80 per cent, meaning only 80 per cent of rental income is counted toward serviceability. These settings determine the maximum loan amount you can access, which in turn determines whether the property can be positively geared.

If rental income is $650 per week but the lender assesses it at $520, and your other income and commitments allow borrowing up to $320,000, purchasing a property above that price requires a larger deposit. A borrower aiming for positive gearing may need to target properties where the purchase price allows a loan amount that keeps repayments below rental income after applying serviceability shading. This is where borrowing capacity modelling before property selection becomes useful, rather than finding a property and discovering the loan structure doesn't support positive cash flow.

Why Positive Gearing Supports Long-Term Portfolio Growth

Positive gearing creates surplus income that can be directed toward paying down other debt, building cash reserves, or funding deposits for additional properties. Under the revised tax settings from July 2027, this approach avoids the problem of accumulating quarantined losses that deliver no immediate tax benefit. A positively geared property still allows deductions for interest, depreciation, and other claimable expenses, but the rental income exceeds costs before applying those deductions.

In our experience, investors who structure their first property to be positively geared find it easier to service a second investment loan application because the existing property contributes to income rather than increasing liabilities. Lenders assess the net position of each investment property when calculating serviceability for additional borrowing. A property producing a $150 weekly surplus improves your borrowing capacity. A property producing a $150 weekly loss reduces it. This difference compounds when building a portfolio over several years.
