Top tips to acquire two investment properties

Why Two Properties Instead of One

Acquiring two investment properties instead of one accelerates portfolio growth and diversifies your rental income. The decision to purchase two properties, rather than a single higher-value asset, typically reflects a deliberate strategy around risk distribution, entry price points, and the compounding benefit of holding multiple appreciating assets.

Consider a buyer with $180,000 in available capital. They could allocate this toward a single property at a higher price point, or structure two separate purchases with smaller deposits. The second approach spreads vacancy risk across two tenancies and two locations. If one property sits vacant for a month, the other continues to generate rental income. In our experience, investors who build a multi-property portfolio early tend to preserve more flexibility as lending conditions tighten over time.

Mount Waverley buyers often start with a local property before looking further afield. The area's proximity to Monash University, established schools like Mount Waverley Secondary College, and consistent rental demand from families and postgraduate students make it a common anchor property. The second property might then be located in a growth corridor or regional centre where entry prices are lower and rental yields are higher.

How Lenders Assess Borrowing Capacity for Two Properties

Lenders calculate your borrowing capacity by applying a serviceability buffer of 3.0 percentage points above the loan product rate, then deducting your existing commitments and living expenses from your net income. When you apply for two investment loans in sequence, the first loan's repayment obligation reduces the capacity available for the second.

In a scenario like this: an investor earns $120,000 annually and borrows $500,000 for the first property at an assessment rate of around 8.5 per cent. The lender assumes an annual repayment of approximately $42,500 on that loan when calculating capacity for the second application. If the investor applies for the second loan six months later, their borrowing power has already contracted by that $42,500 annual commitment, regardless of whether the first loan is principal and interest or interest only.

This is why sequencing matters. Submitting both applications simultaneously, or within a short window, allows the lender to assess the combined exposure before either loan settles. Some lenders will assess both applications together using projected rental income from both properties, rather than treating the first loan as an existing commitment. That difference can preserve tens of thousands of dollars in borrowing capacity.

Debt-to-Income Limits and Portfolio Lending

From 1 February 2026, APRA introduced a debt-to-income lending limit that restricts lenders from writing more than 20 per cent of new investor loans to borrowers with a total DTI ratio of six times or greater. If your total borrowings across both properties exceed six times your gross income, some lenders will decline the application outright, while others may approve it within their allocation.

For an investor earning $140,000, the six-times threshold is $840,000. If the first property requires a loan of $450,000 and the second property requires $420,000, the combined borrowing sits just above that line. The lender's appetite for high DTI lending becomes a material factor. Some institutions reserve their allocation for refinance cases or borrowers with large deposit buffers. Others are more open to new investors who meet serviceability.

We regularly see borrowers who meet serviceability comfortably but are declined on DTI grounds. The rental income from both properties is included in serviceability calculations, but it does not adjust the DTI ratio, which is purely a comparison of debt to gross income. If your combined loan amount is likely to exceed six times your income, speak with a broker who has access to lenders with capacity under the limit, or consider refinancing existing debt to bring the ratio down before applying.

Structuring Deposits Across Two Properties

Most lenders require a minimum 10 per cent deposit for an investment property, though some will lend at higher loan-to-value ratios with lenders mortgage insurance. If you are buying two properties, you need to allocate deposit, stamp duty, and settlement costs across both transactions while leaving enough liquidity to cover any funding gaps.

As an example, an investor purchasing two properties at $600,000 each would need at least $60,000 deposit per property, plus approximately $30,000 in stamp duty per property in Victoria, and another $5,000 to $8,000 per property for settlement costs. That totals around $190,000 to $196,000 in upfront capital, assuming no LMI is paid. If the buyer has $200,000 available, the structure works. If they have $150,000, they will need to either reduce the purchase price, increase the loan amount and pay LMI, or stage the purchases.

Stamp duty in Victoria is calculated on a sliding scale and is generally higher for investment properties than for owner-occupied properties. The duty is payable on or before settlement. Some buyers use offset accounts to park deposit funds until settlement, which keeps the cash accessible and reduces interest costs on any existing loans. Others draw on equity from an existing property, which we cover in the next section.

Using Equity from Your Home to Fund Investment Purchases

If you own your home and have built up equity, you can access that equity to fund the deposit and costs for one or both investment properties. Lenders will typically allow you to borrow up to 80 per cent of your home's value without requiring LMI, though some will go higher if you are prepared to pay the insurance premium.

Consider a buyer who owns a home in Mount Waverley valued at $1.2 million with a remaining mortgage of $400,000. The available equity at 80 per cent LVR is $960,000 minus the existing $400,000, which leaves $560,000. That is enough to fund deposits, stamp duty, and costs for two properties without selling any assets or drawing on savings. The equity is accessed by increasing the loan amount on the home, either through a refinance or a top-up, and the funds are then transferred to cover the investment purchases.

The rental income from the two investment properties will generally be included in the serviceability assessment, but the equity loan repayments are also added to your commitments. The net effect depends on rental yields, loan structure, and the investor's income. In most cases, the ability to acquire two properties without depleting savings outweighs the additional interest cost on the equity loan, particularly if the properties are positively geared or close to neutral after tax deductions.

Interest Only Versus Principal and Interest for Portfolio Growth

Interest only repayments reduce your monthly outgoings during the interest only period, which can help with cash flow and serviceability when building a portfolio. Most lenders offer interest only terms of up to five years on investment loans, after which the loan converts to principal and interest unless you apply for an extension.

For an investor acquiring two properties, switching both loans to interest only reduces the monthly repayment by several hundred dollars per loan compared with principal and interest. That difference improves serviceability, which matters when the lender assesses your capacity for the second loan. It also preserves capital that can be redirected to offset accounts, property maintenance, or further investments.

The downside is that interest only loans attract higher risk weightings under APRA's prudential standards, which can result in slightly higher interest rates and stricter lending criteria. A non-standard interest only loan, defined as one with an LVR above 80 per cent and an interest only period exceeding five years or not specified, is treated even more conservatively. For investors focused on building equity through capital growth, interest only can be a useful tool in the short term, but it does not reduce the loan balance and will eventually convert to higher principal and interest repayments.

Timing Your Applications to Preserve Capacity

Submitting both loan applications together, or as close together as possible, is usually the most efficient approach if you have already identified both properties. A lender can assess both deals in parallel, project rental income from both, and approve both loans before either settles. Once the first loan settles, your borrowing capacity contracts immediately, which can make the second approval harder or impossible.

In practice, investors often identify the first property, settle it, then begin searching for the second. By that point, the first loan has reduced their borrowing power and the pool of willing lenders has narrowed. If the goal is to acquire two properties within a short window, engage a broker early and structure the applications so that both are assessed on your pre-purchase income and commitments. That might mean paying a small holding deposit on the second property before the first one settles, or negotiating longer settlement terms to allow the applications to run concurrently.

Tax Treatment for Properties Acquired After May 2026

From the 2027-28 income year, losses from established residential investment properties acquired after 7:30pm AEST on 12 May 2026 can only be offset against income from other residential properties, not against salary or wages. Excess losses can be carried forward to future years and offset against residential property income, including capital gains. Properties held before that date, or under contract at that time, are grandfathered and continue to allow full negative gearing.

If you are acquiring two properties now, both will likely fall under the new rules unless you exchanged contracts before 12 May 2026. Losses from both properties can still be offset against each other. If one property generates a small profit and the other runs at a loss, the loss can reduce the taxable income from the first property. Losses can also be carried forward and offset against the capital gain when either property is sold. Eligible new builds remain fully negatively geared under the old rules.

The change affects cash flow but does not eliminate the deduction. Interest, property management fees, council rates, insurance, and depreciation remain claimable, and losses are not wasted. They are quarantined to residential property income rather than absorbed into your overall taxable income. For investors building a portfolio, this reinforces the value of holding properties that generate rental income, rather than relying solely on capital growth and negative gearing to subsidise holding costs.

Rental Income and Vacancy Assumptions

Lenders apply a haircut to rental income when assessing serviceability, typically using 80 per cent of the gross rent to account for vacancy periods, management fees, and maintenance costs. If a property generates $600 per week in rent, the lender will include $480 per week, or approximately $24,960 per year, in your income for serviceability purposes.

For two properties, the rental income can provide a meaningful offset to the loan repayments, particularly if both properties are in areas with low vacancy rates. Mount Waverley's vacancy rate has historically remained below 2 per cent, driven by demand from families seeking access to the school zone and postgraduate students attending nearby Monash campuses. A second property in a regional centre or outer growth corridor may have a higher advertised yield but also a higher vacancy rate, which the lender will factor into the assessment.

If both properties are tenanted at the time of application, providing executed lease agreements and evidence of rental payments can strengthen the application. Some lenders will use 100 per cent of the contracted rent for serviceability if the lease is already in place and the tenant has a strong payment history. Others apply the 80 per cent haircut regardless. This is another reason to work with a broker who understands each lender's policy and can match your scenario to the most receptive institution.

Why Speak with a Broker Before You Start Searching

Most buyers begin searching for properties before they understand how much they can borrow across two purchases, or which lenders will support the structure they are proposing. By the time they make an offer, they have often committed to a purchase price or settlement timeline that does not align with their borrowing capacity or the lender's appetite.

A broker can run a detailed serviceability assessment before you make any offers, model the impact of acquiring two properties instead of one, and identify which lenders will assess both applications concurrently. That upfront work prevents wasted time, failed applications, and the risk of settling one property only to find you cannot secure finance for the second.
