Top Strategies to Fund Your First Investment Property

Your first investment property is a different transaction to your home loan.

Lenders assess investor applications using tighter serviceability calculations, require rental income projections that account for vacancy, and apply different deposit and documentation standards. If you're buying after 7:30pm AEST on 12 May 2026, the way you'll be able to claim losses has changed under legislation that received Royal Assent in June. The finance structure you choose now affects not just approval, but your cashflow, tax position and capacity to borrow again.

How Lenders Assess Investment Loan Applications

Lenders calculate serviceability on investment loans by adding only 80 per cent of expected rental income to your assessable income, then applying a 3 percentage point buffer above the actual loan rate. They assume a 20 per cent vacancy and expense allowance regardless of the property type or location. A property generating $600 per week in rent contributes $24,960 to your annual income for serviceability purposes, but lenders assess repayments at a rate roughly 3 per cent higher than you'll actually pay. This compressed income and inflated expense calculation reduces borrowing capacity compared to owner-occupied lending, often by 20 to 30 per cent depending on your other commitments.

Debt-to-income caps came into effect in February. Lenders can now fund only 20 per cent of new investor loans at a debt-to-income ratio of 6 times or greater. If your total lending including the new investment loan exceeds six times your gross annual income, you may need a larger deposit or face a longer approval process while the lender manages its quarterly reporting to APRA.

Interest Only or Principal and Interest Repayments

Interest only repayments reduce your monthly outgoings and preserve cashflow during the holding period. Most lenders offer interest only terms between one and five years on investment loans, after which the loan reverts to principal and interest unless you apply to extend. A loan amount of $500,000 at a variable rate of 6.5 per cent costs roughly $2,708 per month on interest only, compared to $3,160 on principal and interest over 30 years. The difference of $452 per month can be redirected to offset accounts, additional property purchases, or debt reduction on your owner-occupied loan if debt recycling is part of your structure.

Interest only periods suit borrowers with irregular income or those planning to sell or refinance within a defined timeframe. Principal and interest repayments build equity automatically and reduce the outstanding balance, which may improve future borrowing capacity and lower risk if property values stagnate. Your repayment structure should align with your holding strategy and tax position, not with a default recommendation.

Variable Rate, Fixed Rate, or Split Loan Structure

Variable rates on investment loans typically sit between 6.2 and 6.8 per cent depending on the lender, loan to value ratio, and whether you hold other products with that institution. Fixed rates are generally slightly higher but lock in repayments for one to five years. A split structure allocates part of the loan to fixed and part to variable, which limits exposure to rate rises while retaining flexibility to make extra repayments or access offset features on the variable portion.

Consider a pharmacist who purchased an investment property in mid-2026 with a loan amount of $450,000. She fixed 60 per cent of the loan at 6.4 per cent for three years and left 40 per cent variable at 6.5 per cent with a full offset account. The fixed portion provided certainty over holding costs during the first three years, while the variable portion allowed her to park surplus income in offset and reduce interest charges without penalty. When the fixed period expired, she refinanced the entire loan to a lower variable rate as her equity position had improved and the lender offered a rate discount for portfolio customers.

Deposit Requirements and Lenders Mortgage Insurance

Most lenders require a minimum 10 per cent deposit for investment loans, though some will lend at 5 per cent if you're purchasing a new build or meet specific eligibility criteria under profession-based lending policies. Borrowing above 80 per cent loan to value ratio triggers Lenders Mortgage Insurance, a one-off premium added to the loan amount. LMI on an investment loan is typically higher than on an owner-occupied loan due to the increased risk lenders assign to investor lending.

Some lenders offer LMI waivers or capped premiums for pharmacists and other healthcare professionals. If you're eligible, you may be able to borrow with no LMI at loan to value ratios up to 90 or 95 per cent, though investment loans are often excluded from these policies or subject to lower maximum LVR thresholds. Check the specific terms before assuming your profession-based benefits extend to investor finance.

Using Equity from Your Owner-Occupied Property

If you already own a home with equity, you can use that equity as part or all of your deposit for the investment property without selling or refinancing into a larger loan on the original property. Lenders calculate usable equity as 80 per cent of your home's current value, minus the outstanding loan balance. A property worth $800,000 with a $400,000 loan provides $240,000 in usable equity, which is sufficient to fund a deposit and purchase costs on most investment properties below $1 million.

Equity release loans are structured as separate splits secured against your existing property, with each split carrying its own rate and repayment terms. The equity split is typically classified as an investment loan because the funds are used to acquire an income-producing asset, which means the interest is deductible even though the security is your home. Mixing loan purposes on the same security requires careful documentation to ensure deductibility is preserved.

Rental Income, Vacancy Rates, and Cashflow Planning

Rental income must be sufficient to cover most or all of the loan repayments, property management fees, body corporate levies, council rates, insurance, and a buffer for vacancy and maintenance. A property costing $3,200 per month to hold requires gross rental income of roughly $900 per week to break even after the lender's 80 per cent income assessment and allowing for management fees and other outgoings. Properties that are significantly negatively geared may still be serviceable if your salary income is high enough, but the shortfall comes directly from your after-tax income every month.

Vacancy rates vary by location and property type. Inner-city units in high-supply areas may experience longer vacancy periods than houses in established suburbs with strong rental demand. Your lender doesn't adjust the 80 per cent income calculation based on location-specific data, so you need to factor actual vacancy risk and holding costs into your own cashflow model before committing.

Negative Gearing and the July 2027 Tax Changes

Negative gearing allows you to offset rental losses against other income, including your salary, which reduces your taxable income and generates a tax refund. For properties purchased before 7:30pm AEST on 12 May 2026, this treatment continues indefinitely under existing rules. For properties purchased on or after that date and time, new rules take effect from 1 July 2027. Losses from those properties will be quarantined and can only be offset against other residential rental income or carried forward to offset future rental income or capital gains from residential property. You cannot offset the loss against your pharmacy salary or other non-residential income.

Eligible new residential dwellings are exempt from the quarantine. A new dwelling is defined as one constructed on previously vacant land, or one that increases the total number of dwellings on a site. Knock-down rebuilds that don't increase dwelling numbers, and substantial renovations, are not eligible. If you're planning to purchase in the next 12 months and intend to rely on negative gearing to support serviceability or tax outcomes, buying an eligible new build preserves that capacity beyond July 2027.

Claimable Expenses and Maximising Deductions

Interest on borrowings used to purchase or hold the investment property is fully deductible. Other claimable expenses include property management fees, council and water rates, building insurance, landlord insurance, body corporate levies, repairs and maintenance, depreciation on plant and equipment, and capital works deductions for the building structure if it qualifies. Stamp duty and other purchase costs are not immediately deductible but form part of the cost base for capital gains tax purposes when you sell.

Loan establishment fees, valuation fees, and mortgage insurance premiums are deductible over five years or the loan term, whichever is shorter. Keep all receipts and invoices, and separate expense records by property if you hold more than one. Your accountant will need a complete record to prepare your tax return and calculate depreciation schedules.

Capital Gains Tax and the Cost Base Indexation Change

When you sell an investment property, you pay capital gains tax on the difference between the sale price and your cost base, which includes the purchase price, stamp duty, legal fees, and capital improvements. Under current rules, individuals receive a 50 per cent discount on the taxable gain if the property is held for more than 12 months. From 1 July 2027, gains that accrue after that date on properties purchased on or after 7:30pm AEST on 12 May 2026 will no longer receive the 50 per cent discount. Instead, your cost base will be indexed annually using the Consumer Price Index, and the real gain will be taxed at a minimum rate of 30 per cent.

Gains that accrued before 1 July 2027 on properties you already own continue under the existing 50 per cent discount rules. The new arrangements apply only to gains accruing after 1 July 2027. Eligible new build properties allow you to elect between the 50 per cent discount and the indexed cost base with the 30 per cent minimum rate, giving you flexibility to choose the most beneficial treatment at the time of sale.

Structuring for Portfolio Growth

Your first investment property is rarely your last if wealth accumulation is the goal. How you structure the first loan affects your ability to borrow again. Holding the investment loan in your own name is the most common structure for salaried pharmacists, though some borrowers use discretionary trusts or corporate trustees to separate liability or distribute income to other family members. Trusts add cost and complexity, and most lenders apply higher rates or stricter serviceability to trust borrowers.

Keeping the investment loan separate from your owner-occupied loan simplifies record-keeping and preserves deductibility. Avoid redrawing from the investment loan for private purposes, as redrawn amounts lose their deductibility even though the loan remains secured against the investment property. If you plan to expand your property portfolio in future, maintaining clear loan separation and building offset balances on the owner-occupied side gives you the flexibility to access equity and demonstrate serviceability without contaminating the investment loan structure.
