Simple hacks to finance two investment properties

Acquiring two investment properties requires more than twice the deposit.

When you move from one property to two, the challenge shifts from saving a deposit to managing serviceability across multiple loans while preserving enough borrowing capacity for the second purchase. For buyers targeting Frankston, where rental yields remain solid and vacancy rates sit below the Melbourne average, the opportunity exists but the sequencing matters.

Borrowing capacity across two properties

Your ability to service two investment loans depends on how lenders assess rental income and existing debt. Most lenders apply a discount to rental income, typically using 70 to 80 per cent of the gross rent when calculating serviceability. That means a property renting for $500 per week contributes $350 to $400 towards your borrowing capacity, not the full amount.

At the same time, lenders add a three percentage point buffer to the loan's interest rate when testing whether you can afford repayments. If the product rate is 6.2 per cent, you will be assessed at 9.2 per cent. Across two properties, that buffer compounds quickly. A buyer with $120,000 in annual household income might comfortably service one investment loan but struggle to meet serviceability tests for a second without adjusting the loan structure or drawing on additional equity.

Debt-to-income caps also apply. Since February, lenders can only approve 20 per cent of new investor loans at a debt-to-income ratio of six times or higher. If your total borrowing across both properties pushes you above that threshold, some lenders will decline the application outright while others may approve it under their restricted allocation.

Sequencing the purchases: which property comes first

Buying the lower-priced property first gives you a head start on equity growth and rental income, both of which help you qualify for the second loan. In Frankston, a two-bedroom unit close to the station can be acquired for considerably less than a three-bedroom house in the Frankston South pocket, and the rental return as a percentage of purchase price is often higher.

Consider a buyer who purchases a unit generating $450 per week in rent. Within 18 months, that property may have gained enough equity to support a refinance or top-up, and the rental income will be factored into serviceability for the second purchase. If that buyer had started with the more expensive house, the deposit required would have absorbed more cash upfront, leaving less flexibility for the second transaction.

Timing also influences your tax position. Under the revised negative gearing rules that take effect from July next year, rental losses on properties acquired from May this year onward can only be offset against other residential rental income or carried forward. If you acquire both properties in quick succession, losses from the first can offset income from the second once it settles, rather than being quarantined in isolation.

Deposit and equity strategies for the second property

The second deposit does not always need to come from savings. If the first property has gained value or you hold equity in an owner-occupied home, you can access that equity to fund the next purchase. Lenders will typically allow you to borrow up to 80 per cent of a property's value without paying Lenders Mortgage Insurance, which means a property valued at $600,000 can support a loan of $480,000. If your existing loan sits at $450,000, you have $30,000 in usable equity before crossing the 80 per cent threshold.

Releasing equity does increase your total debt, and that debt still needs to meet serviceability tests across all loans. The advantage is speed: you can move on the second property without waiting to accumulate another cash deposit. The risk is over-leverage if values fall or rental income drops.

For buyers without existing property, both deposits need to come from genuine savings, gifted funds, or proceeds from the sale of other assets. A 10 per cent deposit on each property is the minimum most lenders will accept for investment purposes, though some will go as low as 5 per cent if you are willing to pay LMI. Stamp duty and settlement costs sit on top of that deposit, and those costs are not capitalised into the loan.

Loan structure: split, offset, interest-only considerations

Most investors hold their loans on an interest-only basis for the first few years to reduce cash outflows and rely on capital growth to build equity. Interest-only terms typically run for one to five years before reverting to principal and interest, at which point repayments increase. If you are holding two properties on interest-only terms and both revert to principal and interest simultaneously, the serviceability shock can be significant.

Splitting the loan between fixed and variable rates offers some protection against rate movements while maintaining the flexibility to make extra repayments on the variable portion. Fixed rates also lock in your repayment amount, which makes cash flow forecasting more predictable when you are managing two loans. Variable portions allow you to link an offset account, which can reduce interest costs if you are accumulating cash between purchases or holding funds for future renovations.

In our experience, buyers acquiring two properties within a short window often structure the first loan as variable with offset and the second as a mix of fixed and variable. That combination preserves flexibility on the first property while managing rate risk on the second.

Frankston-specific factors: market dynamics and rental demand

Frankston's investor appeal sits in its rental yield and accessibility. The suburb attracts tenants working locally in healthcare, education and retail, as well as those commuting to the Dandenong employment corridor or Melbourne CBD via the Frankston line. Proximity to Monash University's Peninsula campus adds a layer of student and academic demand, particularly for units and townhouses within walking distance of public transport.

Rental vacancy rates in Frankston have remained below 2 per cent over the past 18 months, reflecting steady tenant demand and limited new supply. Body corporate fees on older unit complexes can reduce net rental returns, so it pays to compare strata costs across buildings before committing. Houses in the Frankston South and Seaford Rise areas tend to attract families on longer leases, while units closer to the CBD and Bayside Shopping Centre see higher turnover but also faster re-letting.

If you are buying two properties in the same suburb, diversifying property type reduces your exposure to shifts in one segment of the rental market. A unit and a house, rather than two units, spreads tenant risk and may improve your overall portfolio performance if family demand strengthens or unit supply increases.

Structuring loans to support future portfolio growth

Once you hold two investment properties, your borrowing capacity for a third becomes constrained unless you have significant income growth, pay down existing debt, or sell one property to release equity. Lenders assess your entire debt position each time you apply for new finance, and the serviceability test applies across all loans.

If further portfolio growth is part of your plan, consider structuring each loan with its own facility so you can refinance or adjust terms on one property without affecting the other. Cross-collateralised loans, where multiple properties secure a single facility, can limit your ability to sell or refinance individual assets without lender consent.

Keeping loans separate also simplifies record-keeping for tax purposes. Interest on each loan is deductible only to the extent the borrowing relates to the income-producing property, so mixing funds across properties or redrawing for private purposes can create complications when claiming deductions. Clean loan structures make tax time less painful and give you more control if you decide to sell one property and hold the other long term.

Tax treatment and the new negative gearing landscape

From July next year, rental losses on residential properties acquired from May this year can only be offset against other residential rental income or carried forward. If you acquire two properties and both produce rental losses in the same financial year, those losses can offset each other but cannot reduce your salary or wage income.

Properties purchased before May this year are grandfathered under the existing rules, meaning losses can still be offset against any income. If you are acquiring two properties and one settles before that cut-off and the other after, the earlier property retains full negative gearing while the second operates under the new quarantine.

Eligible new builds remain exempt from the quarantine, so an investor acquiring one established property and one newly constructed dwelling on previously vacant land can still offset losses from the new build against salary. That distinction creates an incentive to include at least one new build in a two-property strategy, though supply of new stock in Frankston is limited and pricing tends to sit at a premium to established homes.

Interest, property management fees, council rates, insurance, repairs and depreciation remain claimable under both the old and new rules. The change affects only where losses can be used, not whether expenses are deductible in the first place. Investors holding two properties will need to track income and expenses separately for each to ensure losses are applied correctly and carried forward where necessary.
