Top Strategies to Secure Positive Geared Investment Loans

Positive Gearing in Darwin: Why It Works

Positive gearing occurs when rental income exceeds all property holding costs, including loan repayments, rates, insurance and management fees.

Darwin's rental yields sit among the highest in Australia, regularly above 5.5 per cent for units and around 4.5 to 5 per cent for houses. Combined with relatively stable median prices, this creates opportunities for positive cash flow investment loans that are difficult to replicate in capital city markets. Investors who rent in Darwin's inner suburbs while owning a positively geared property elsewhere can offset their own rent costs with surplus rental income, reducing the financial strain of carrying two properties.

Consider a buyer who acquires a two-bedroom unit in Nightcliff at the suburb's current median, borrowing 80 per cent of the purchase price. With weekly rent around $550 and principal-and-interest repayments at current variable rates, the property clears roughly $150 to $200 per week after all costs. That surplus income is assessable, meaning tax is payable, but the investor receives cash flow rather than funding a shortfall each month.

Loan Structure: Principal and Interest Versus Interest Only

Principal-and-interest repayments reduce the loan balance each month, building equity and lowering total interest paid over time.

Interest-only investment loans produce lower monthly repayments, which can turn a neutral or slightly negative property into a positive one on paper. However, interest-only terms are typically capped at five years, after which the loan reverts to principal and interest unless renegotiated. Under APS 112, interest-only loans with an LVR above 80 per cent and a contractual interest-only period exceeding five years are classified as non-standard, attracting higher risk weights and pricing.

For Darwin investors targeting genuine long-term cash flow, principal-and-interest repayments provide certainty. The weekly surplus remains positive even after the repayment structure changes, and equity grows automatically. Interest-only structures suit investors who plan to sell within five years or who prioritise deduction maximisation over cash flow stability.

Darwin's Rental Market and Vacancy Considerations

Rental supply in Darwin tightened noticeably following Cyclone Megan in early 2025, which displaced tenants and removed stock from the market temporarily.

Vacancy rates in Darwin fluctuate more than southern capitals due to the Defence presence, cyclone season and the transient nature of resource sector employment. A positively geared loan only remains positive if the property is tenanted. Investors should model cash flow assuming at least two to three weeks of vacancy per year, plus one week for maintenance or tenant changeover. Properties in Coconut Grove, Fannie Bay and Nightcliff tend to attract longer-term tenants due to proximity to schools, hospitals and the waterfront, reducing turnover risk.

Rental income is assessed by lenders at 80 per cent of the gross figure to account for vacancy and costs. This affects borrowing capacity but does not change the actual cash flow once the property is tenanted and performing.

How Debt-to-Income Limits Affect Positive Gearing

APRA's debt-to-income lending limits, active from 1 February 2026, cap the portion of new investor loans at six times income or greater to 20 per cent of each lender's quarterly investor lending.

Positively geared properties improve serviceability because rental income contributes to the borrower's total income, reducing the effective DTI ratio. However, lenders assess rental income at 80 per cent, so a property generating $550 per week is credited as $440 per week for serviceability purposes. For Darwin investors with moderate incomes, positive gearing can be the difference between approval and refusal under the DTI framework, particularly when purchasing a second or third property.

Serviceability is tested at the loan product rate plus a 3.0 percentage point buffer. A borrower earning $90,000 per year and purchasing a positively geared property with $440 per week in assessed rental income has a combined income of approximately $113,000 for serviceability purposes, materially improving their position.

Fixed Versus Variable Rates on Positively Geared Loans

Fixed rates lock in repayments for one to five years, providing certainty over cash flow and protecting against rate rises.

Variable rates allow additional repayments, redraw and offset facilities, and typically fall faster than fixed rates when the Reserve Bank eases policy. For positively geared loans, the choice depends on whether the investor values certainty or flexibility. Darwin's rental market can experience sudden demand shifts due to Defence relocations or resource projects, and a variable rate allows the investor to increase repayments during high-occupancy periods without penalty.

Split loans combine both structures, fixing a portion of the loan to protect baseline cash flow while keeping the remainder variable for flexibility. A 50/50 split on a positively geared loan ensures the investor benefits from rate cuts while maintaining predictable minimum income.

Maximising Deductions While Staying Cash Flow Positive

Positive gearing does not eliminate tax deductions; it simply means deductions are smaller than rental income, resulting in assessable income rather than a loss.

All interest on the investment loan remains deductible, as do council rates, insurance, property management fees, repairs and depreciation. For a Darwin unit purchased at current median prices, annual depreciation can exceed $5,000 in the early years, particularly for properties built after 2017. Depreciation is a non-cash deduction, meaning it reduces taxable income without affecting cash flow.

Investors sometimes assume positive gearing forfeits tax benefits. In reality, a positively geared property still generates deductions; the investor simply pays tax on the net rental profit. For a Darwin investor earning $95,000 per year with $8,000 in net rental income after all deductions, the additional tax liability is roughly $3,200, leaving $4,800 in after-tax cash flow. That outcome is preferable to funding a $5,000 annual shortfall on a negatively geared property and receiving a $2,000 tax refund.

Refinancing to Improve Cash Flow on Existing Investment Loans

Investors who purchased in Darwin between 2020 and 2023 may be carrying loans with rates above current market offers.

Investment loan refinancing can reduce repayments by 0.3 to 0.6 percentage points, depending on the lender and loan size. On a loan amount of $400,000, a 0.4 percentage point reduction saves approximately $130 per month, converting a neutral or slightly negative property into a positively geared one without any change to rental income. Refinancing also provides an opportunity to restructure the loan, switch from interest-only to principal and interest, or consolidate multiple properties under a single lender for portfolio discounting.

Lenders assess refinance applications using current serviceability rules, including the 3.0 percentage point buffer and DTI limits where applicable. Positively geared properties improve the investor's position and increase the likelihood of approval, particularly where the original loan was written under looser criteria.

Rentvesting and Positive Gearing: The Darwin Opportunity

Rentvesting allows Darwin residents to own interstate or regional property while continuing to rent locally.

For renters in Darwin's inner suburbs, where weekly rent on a modern two-bedroom apartment can reach $600 to $700, owning a positively geared property elsewhere offsets that cost. The rental income from the investment property covers part or all of the investor's own rent, creating a financially neutral position while building equity. Darwin's high rental yields make this strategy particularly effective, as the income generated often exceeds what investors would achieve purchasing in southern capitals at similar price points.

Rentvesting loans are structured as standard investment loans, with rental income assessed at 80 per cent and the investor's own rent treated as a living expense. Lenders do not penalise rentvesting strategies, but the investor must demonstrate sufficient income to service both the investment loan and their ongoing rental commitment.

New Builds and the Legislative Advantage

Eligible new builds retain full negative gearing treatment from the 2027-28 income year, even if purchased after 12 May 2026.

For Darwin investors, this creates a decision point: purchase an established property with immediate positive cash flow, or purchase a new build that may be neutral or slightly negative in the short term but preserves access to full loss deductibility and the choice between the existing 50 per cent CGT discount and indexed cost base treatment on disposal. New builds also attract higher depreciation deductions, typically $8,000 to $12,000 per year for the first decade, which can convert a neutral property into a positively geared one purely through non-cash deductions.

Darwin's apartment market includes several new developments in Waterfront, The Gardens and Stuart Park. Investors should confirm that the property meets the definition of an eligible new build under Schedule 2 of the Treasury Laws Amendment (Tax Reform No. 1) Act 2026 before assuming the exemption applies.
