Simple hacks to choose the right investment property type

The property type you choose determines your rental return and capital growth potential

The structure, layout and zoning of your investment property directly affect rental demand, vacancy periods, and capital growth.

A three-bedroom house in Oakleigh South with a backyard will attract families looking for longer tenancies, while a two-bedroom unit closer to Huntingdale Station may appeal to renters who prioritise proximity to the Cranbourne and Pakenham train lines. Each property type carries different holding costs, attracts different tenants, and responds differently to shifts in the rental market.

Consider a buyer who borrows to purchase a two-bedroom townhouse in a small development near Oakleigh Reserve. The body corporate fees are modest, the rental yield is reasonable at current variable rates, and the property attracts professional couples who tend to stay for two to three years. The borrower structures the loan as interest-only for the first five years to maximise tax deductions while keeping monthly outgoings lower. Within three years, the property has appreciated in line with the broader Oakleigh South market, and the owner uses the equity release to fund a deposit on a second property. That outcome was possible because the property type matched the borrower's income, risk tolerance, and timeline.

Houses deliver stronger capital growth but require higher deposits

Standalone houses in Oakleigh South typically require a larger deposit than units or townhouses at the same purchase price.

Lenders apply loan-to-value ratio caps to reduce risk. Under the prudential framework, investment loans above 80 per cent LVR generally require Lenders Mortgage Insurance, and the premium increases sharply as the LVR rises. A house valued higher than the suburb median may push your LVR above 80 per cent unless you contribute a larger deposit or draw on equity from another property.

Houses also attract families, which can mean longer tenancies and fewer vacancy periods. Rental income from a three or four-bedroom house with off-street parking and a yard tends to be more stable than income from a studio apartment, particularly in a suburb like Oakleigh South where demand for family housing remains consistent. However, holding costs are higher. Council rates, insurance premiums, and maintenance expenses for a house exceed those for a unit, and there is no body corporate to share responsibility for common area repairs.

Units and townhouses offer lower entry costs and manageable holding expenses

Units and townhouses allow investors to enter the market with a smaller deposit and lower stamp duty.

A two-bedroom unit in Oakleigh South may be purchased at a price point that leaves room for your borrowing capacity to stretch to a second property sooner. Body corporate fees are an additional cost, but they cover building insurance, common area maintenance, and sometimes water usage, which can simplify budgeting. Rental yields on well-located units are often higher than on houses, particularly where the property is within walking distance of Huntingdale or Clayton train stations.

The trade-off is that capital growth on units tends to lag behind houses over the long term, especially in markets where land value drives appreciation. Units in larger apartment complexes may also experience higher vacancy rates if supply in the area increases. Before committing to a unit or townhouse, review the body corporate records for the development. High levies, upcoming special levies, or poor building maintenance can erode your rental return and make refinancing difficult if the lender's valuer flags concerns.

New builds preserve full negative gearing beyond the 2027-28 income year

New builds constructed on previously vacant land, or where the number of dwellings on the site has increased, remain eligible for full negative gearing under the exemption provisions of the Treasury Laws Amendment (Tax Reform No. 1) Act 2026.

For properties acquired after 7:30pm AEST on 12 May 2026, losses from established dwellings can only be offset against income from other residential properties from the 2027-28 income year onward. Losses from eligible new builds continue to be deductible against all income, including salary and wages. This distinction can have a material impact on after-tax cash flow, particularly in the first few years of ownership when interest costs, depreciation, and other deductible expenses typically exceed rental income.

New builds also offer higher depreciation deductions than established properties. Plant and equipment items such as ovens, air conditioners, and carpets can be depreciated over time, and the building structure itself can be depreciated over 40 years. Established properties purchased after May 2017 no longer allow depreciation on second-hand plant and equipment unless you are the first owner of those items. For investors seeking to maximise tax deductions, the combination of full negative gearing eligibility and depreciation makes new builds worth serious consideration, provided the purchase price reflects realistic capital growth prospects and the rental yield is sufficient to service the loan.

Off-the-plan purchases require careful loan structuring and timing

Off-the-plan contracts involve a settlement date that may be 12 to 24 months after signing.

Lenders typically issue loan pre-approval valid for three to six months, which often expires before the property is complete. You will need to reapply closer to settlement, and the lender will reassess your income, expenses, and borrowing capacity at that time. If your financial position has changed, or if the lender has tightened credit policy, you may not receive the same loan amount or rate discount originally indicated.

Valuation risk is another consideration. If the property is valued below the contract price at settlement, the lender will base the loan on the lower valuation figure. You will need to make up the shortfall in cash, or negotiate with the developer, or walk away from the contract and forfeit your deposit. In practice, developers in Oakleigh South and surrounding suburbs have generally delivered projects in line with presale expectations, but valuation shortfalls do occur, particularly where supply in the immediate area has increased between contract and settlement. Before signing an off-the-plan contract, confirm the cooling-off period, review the sunset clause, and understand your rights if the project is delayed or the developer seeks to rescind the contract.

Fixed rate or variable rate structures depend on your cash flow and risk tolerance

Most investors structure their loan as variable rate or a combination of fixed and variable.

Variable rates allow full access to offset accounts, unlimited additional repayments, and the flexibility to refinance without break costs. If you plan to sell the property or draw on equity within a few years, variable rate structures offer more control. Offset accounts linked to an investment loan reduce the interest charged each month, which increases your deductible interest expense and improves after-tax cash flow. Any funds held in the offset account remain accessible, which can be useful if you are building a deposit for a second property or managing irregular expenses.

Fixed rates lock in your repayments for a set term, typically one to five years, and can provide certainty if your budget is tight or you expect rates to rise. However, fixed rate products generally restrict additional repayments to a capped annual amount, do not offer offset accounts, and impose break costs if you exit the loan early. Break costs can be substantial if rates have fallen since you fixed. For investors planning to hold the property long term and wanting predictable repayments, a partial fix on 50 to 70 per cent of the loan amount can balance certainty with flexibility.

Interest-only terms reduce monthly repayments but increase total interest cost

Interest-only terms are common for investment property loans because they reduce monthly repayments and allow investors to claim a higher interest deduction.

During the interest-only period, you pay only the interest component each month. The loan balance does not reduce, which means the property must generate sufficient capital growth or rental income to justify the higher total interest cost over the life of the loan. Interest-only periods are typically available for up to five years on standard investment loans. At the end of the interest-only period, the loan reverts to principal and interest repayments unless you request an extension or refinance.

Interest-only structures suit investors who prioritise cash flow and tax efficiency in the short term and intend to sell the property or refinance before the principal and interest repayments commence. They are less suitable if your goal is to pay down debt over time or if rental income is unlikely to cover the higher principal and interest repayments once the interest-only term ends. Lenders assess interest-only applications using the same serviceability buffer as principal and interest loans, and under APS 112, interest-only investment loans generally attract higher risk weights, which can affect pricing.

Borrowing capacity for investment loans depends on rental income and existing commitments

Lenders assess your ability to service an investment loan by adding 80 per cent of the expected rental income to your other income and subtracting all expenses, including the proposed loan repayment calculated at the product rate plus the serviceability buffer.

The 80 per cent figure, sometimes referred to as a rental income shading factor, accounts for vacancy periods, maintenance costs, and property management fees. The actual shading percentage varies by lender and may be higher or lower depending on the property type, location, and your overall portfolio. If you already hold investment property, the lender will include the full repayment amount for those loans in your expense assessment, even if the loans are interest-only or have an offset balance.

From 1 February 2026, APRA's DTI lending limit restricts the proportion of new investment loans each bank can write to borrowers with a total debt-to-income ratio of six times or greater to 20 per cent of quarterly lending. The limit applies to total debt, including owner-occupied and investment loans, measured against your gross income. If your total borrowings across all properties exceed six times your annual income, some lenders may decline your application or require a larger deposit to reduce the loan amount and bring your DTI below the threshold. This does not mean you cannot borrow, but it may narrow your choice of lender and require more detailed financial documentation.

Structuring multiple loans across properties preserves flexibility for future portfolio growth

Investors building a portfolio often hold separate loan accounts for each property rather than consolidating debt into a single facility.

Separate loan accounts allow you to sell one property and discharge its loan without affecting the others. They also make it simpler to track deductible interest for each property, which is necessary for accurate tax reporting. If you draw on equity from your owner-occupied home to fund a deposit on an investment property, the equity loan should be held in a separate split linked to the investment property. Interest on that split is deductible because the funds were used for investment purposes, while interest on the split used for owner-occupied purposes is not.

Some investors establish a line of credit secured against equity in one property and use it to fund deposits on subsequent purchases. This approach can accelerate portfolio growth, but it increases your total debt and requires careful cash flow management. The interest on the line of credit is deductible only to the extent the borrowed funds are used to acquire or hold income-producing assets. If you redraw funds for private purposes, that portion of the interest becomes non-deductible.

Oakleigh South investors benefit from proximity to Monash University and Parkmore Shopping Centre

Oakleigh South sits within the City of Kingston and borders Clayton and Huntingdale, both of which are high-demand rental precincts due to their proximity to Monash University's Clayton campus.

Rental demand in Oakleigh South is supported by postgraduate students, hospital workers from Monash Medical Centre, and families seeking access to local primary schools. Properties within a short drive or bus ride of Parkmore Shopping Centre or Huntingdale Station typically achieve shorter vacancy periods and attract tenants who value convenience. The suburb has a mix of detached houses, older-style units, and newer townhouse developments, which means rental yields and capital growth vary depending on property age, condition, and location within the suburb.

When assessing a property in Oakleigh South, consider the rental profile of the immediate street and surrounding area. Streets closer to the Princes Highway may experience higher traffic noise but offer better access to public transport and retail amenities. Quieter streets backing onto Oakleigh South Primary School or near Bald Hill Park may appeal more to families and command slightly higher rent for houses, but may take longer to lease if the tenant pool is narrower.

Your serviceability depends as much on your existing commitments as on the property you are buying

Your borrowing capacity is shaped by your current debts, credit card limits, and living expenses.

Lenders include the repayment amount for all existing home loans, personal loans, car loans, and the monthly limit on every credit card you hold, even if the balance is zero. Closing unused credit cards or reducing limits before applying for an investment loan can increase your borrowing capacity by several thousand dollars. If you have recently changed jobs, some lenders require a minimum employment period before approving a loan, while others accept a signed contract and evidence of your first pay. Self-employed borrowers generally need two years of tax returns and financial statements, although some lenders offer alternative documentation pathways for applicants with strong asset positions or significant cash reserves.

The APRA serviceability buffer means you must demonstrate capacity to service the loan at a rate three percentage points above the product rate. If the lender offers a variable rate of 6.2 per cent, you will be assessed at 9.2 per cent. For an investment loan, rental income is shaded to 80 per cent, so the after-shading rental income must cover the higher assessed repayment in combination with your other income. If your borrowing capacity falls short, options include increasing your deposit, adding a co-borrower, reducing other debts, or selecting a property with higher rental yield.
