Smart ways to approach investment property selection

Choosing the right investment property determines whether your borrowing works now and whether your portfolio grows later.

Property selection is the part of investment strategy that gets decided once and influences returns for years. The loan structure, interest rate and deposit size all matter, but the property itself controls rental income, vacancy patterns, capital growth potential and whether a lender will finance it at all. For self-employed borrowers and working professionals in Bondi Junction, understanding how lenders assess investment property risk makes it possible to select a property that not only suits your goals but also maximises your borrowing capacity.

How lenders assess investment property risk

Lenders treat investment loans differently from owner-occupied loans. Under APRA Prudential Standard APS 112, investor loans attract higher risk weights than owner-occupied loans at the same loan-to-value ratio. That translates to stricter serviceability assessments and, in some cases, a lower borrowing ceiling even when your income is identical.

Consider a self-employed accountant in Bondi Junction looking at a two-bedroom unit in Rushcutters Bay. Rushcutters Bay units offer a median rental yield of approximately 4.76 per cent, among the strongest in the Eastern Suburbs. The lender will assess serviceability at a rate at least 3.0 percentage points above the loan product rate and will apply an 80 per cent income shading factor to the expected rental income. That means if the property is expected to rent for $650 per week, only $520 of that income is recognised in the serviceability calculation. The shortfall between the loan repayment and the shaded rental income must be covered by the borrower's assessable income. For self-employed borrowers, assessable income is typically the lower of the most recent year's net profit or the average of the past two years, which makes rental yield a critical part of the affordability equation.

Property type and borrowing capacity

Not all property types are treated the same way by lenders. A two-bedroom apartment in a well-maintained building with low body corporate fees and no special levies will generally support a higher loan amount than a studio in a complex with deferred maintenance or high owner-occupier turnover.

As an example, a working professional earning a salary of $140,000 per year might be looking at either a studio unit in Double Bay or a two-bedroom unit in Bondi Junction. The Double Bay studio might have a body corporate fee of $4,500 per quarter and a rental return of $650 per week. The Bondi Junction two-bedroom unit might have a body corporate fee of $1,800 per quarter and a rental return of $750 per week. After shading rental income to 80 per cent, the Bondi Junction property delivers an additional $80 per week in recognised income and costs $2,700 less per year in holding costs. Across a 30-year loan term, that difference in serviceability can translate to a borrowing capacity increase of $40,000 to $60,000, depending on the lender's assessment rate and the borrower's other commitments.

Some lenders also apply postcode-based servicing overlays or refuse to lend on certain property types altogether, such as studios under 40 square metres, properties with short remaining lease terms, or apartments in buildings with known cladding issues. Checking a property's eligibility before making an offer avoids wasted time and contract risk.

Rental yield and cash flow management

Rental yield is the annual rental income expressed as a percentage of the property's purchase price. It determines how much of the loan repayment is covered by rent and how much needs to come from your own income. For investors purchasing investment property in the Eastern Suburbs, yield varies significantly by suburb and property type.

Units in Rushcutters Bay and Bondi Junction deliver yields between 4.0 and 4.8 per cent, while prestige suburbs such as Bellevue Hill, Double Bay and Rose Bay deliver house yields between 1.0 and 2.0 per cent. A property purchased for capital growth in Bellevue Hill at a 1.09 per cent yield will require significant ongoing cash contribution to cover the gap between rent and repayment, particularly if the loan is structured on a principal-and-interest basis. A property in Bondi Junction at a 4.0 per cent yield on an interest-only loan may be close to cash flow neutral, depending on the interest rate and the borrower's tax position.

Yield also affects your ability to expand your portfolio. If your first investment property requires a monthly top-up of $1,500 to cover the shortfall, that ongoing cost reduces your surplus income and therefore reduces your borrowing capacity for a second property. Selecting a property with stronger rental yield on the first purchase preserves serviceability for subsequent acquisitions. That matters particularly for borrowers planning portfolio growth over a five to ten-year horizon.

Location and tenant demand

Tenant demand drives both occupancy rates and rental growth. Properties located within walking distance of transport, employment hubs, schools and retail amenities consistently attract stronger tenant interest and experience lower vacancy periods.

Bondi Junction is one of Sydney's largest retail and transport hubs, with Westfield Bondi Junction, direct train access to the CBD, and a large employment base. Properties within 800 metres of the Junction typically achieve rental yields between 4.0 and 5.0 per cent and maintain low vacancy rates due to consistent demand from professionals working locally or commuting to the CBD. Paddington, with its Victorian terraces and proximity to the city, Moore Park and the entertainment precinct, attracts a different tenant profile but similarly benefits from infrastructure and amenity.

When assessing location, vacancy rate is as important as rental yield. A property that achieves $50 per week more in rent but sits vacant for an additional four weeks per year delivers the same annual income as a property with slightly lower rent and no vacancy gap. Lenders apply a standard vacancy factor in their serviceability assessments, but the real cost of extended vacancy falls entirely on the investor. Choosing a property in an area with strong tenant demand reduces that risk.

New build versus established property under current tax rules

Under the Treasury Laws Amendment (Tax Reform No. 1) Act 2026, losses from residential investment properties acquired after 7:30pm AEST on 12 May 2026 are deductible only against other income from residential properties from the 2027-28 income year onward. Properties classified as eligible new builds are exempt from this restriction and retain the ability to deduct losses against all income, including salary and wages.

An eligible new build includes dwellings constructed on previously vacant land and dwellings replacing existing properties where the number of dwellings increases. Knock-down rebuilds that do not increase dwelling numbers, and substantial renovations, are not eligible. A new build occupied for more than 12 months before sale to a subsequent investor loses access to negative gearing for that subsequent purchaser.

For a self-employed borrower in Bondi Junction considering whether to purchase an established apartment in Paddington or a new apartment in a recently completed development, the tax treatment is materially different. The Paddington apartment, if acquired after 12 May 2026, will allow losses to be offset only against residential property income from the 2027-28 income year onward. The new apartment will allow losses to be offset against the borrower's business income and salary in all years. For a borrower with assessable income of $160,000 per year and an expected annual loss on the investment property of $12,000, the ability to offset that loss against all income delivers a tax benefit of approximately $4,400 per year at current marginal rates. Over a ten-year holding period, that difference compounds significantly.

New builds also offer access to depreciation on plant and equipment and building cost allowances that are not available or have been substantially exhausted on established properties. However, new builds in prestige suburbs are less common and often carry a price premium. The decision depends on the borrower's income profile, tax position and whether the capital growth differential justifies the entry price.

Deposit size, LVR and Lenders Mortgage Insurance

The loan-to-value ratio on an investment loan determines whether Lenders Mortgage Insurance is required and influences the interest rate offered. Most lenders require LMI on investment loans where the LVR exceeds 80 per cent. The premium is calculated on a sliding scale based on the loan amount and LVR and is payable by the borrower, either as an upfront cost or capitalised into the loan.

For a property purchased at $900,000 with a 10 per cent deposit, the LVR is 90 per cent and LMI might cost between $18,000 and $25,000 depending on the lender and the borrower's risk profile. Increasing the deposit to 20 per cent eliminates the LMI cost entirely. For borrowers with access to equity in their existing home or savings, structuring the investment loan at 80 per cent LVR can reduce upfront costs and improve cash flow.

Some lenders also offer lower interest rates at lower LVRs. A borrower with an 80 per cent LVR might be offered a rate 0.10 to 0.20 percentage points lower than a borrower at 90 per cent LVR, even after accounting for LMI. Over the life of a loan, that difference in rate can exceed the cost of LMI, making a larger deposit the more economical choice where funds are available.

Borrowers looking to use equity release from an existing property to fund the deposit on an investment property should be aware that the equity loan itself is assessed as part of overall serviceability. Releasing equity increases total debt and reduces surplus income, which may lower the amount that can be borrowed for the investment property. Working through the numbers before committing to a purchase price is essential.

Interest-only versus principal-and-interest repayments

Investment loans can be structured as interest-only or principal-and-interest. Interest-only loans require repayment of interest charges only during the interest-only period, typically up to five years, with the principal balance remaining unchanged. Principal-and-interest loans require repayment of both interest and a portion of the principal each month, reducing the loan balance over time.

Interest-only repayments are lower than principal-and-interest repayments, which improves cash flow and may increase borrowing capacity. For a loan of $720,000 at a variable rate, the monthly repayment on an interest-only basis might be approximately $3,200, while the repayment on a principal-and-interest basis might be approximately $4,100. The $900 per month difference can be the margin that makes an investment property serviceable, particularly for self-employed borrowers with variable income.

However, lenders assess interest-only investment loans at the principal-and-interest repayment rate when calculating serviceability, so the benefit is not as large as it appears. The primary advantage of interest-only is the actual cash flow relief during the interest-only period, not a higher approved loan amount. At the end of the interest-only period, the loan either reverts to principal-and-interest or can be refinanced to a new interest-only term, subject to the lender's criteria at that time.

For borrowers planning to sell the property or refinance the investment loan within five years, interest-only can reduce holding costs without materially affecting the sale outcome. For borrowers planning to hold long-term, principal-and-interest reduces the loan balance and builds equity, which can be used to fund additional purchases.

Property condition and future capital expenditure

Properties requiring significant near-term capital expenditure reduce net cash flow and may trigger special levies that affect serviceability. A unit in an older building with original lifts, aging plumbing or no sinking fund for future works carries higher risk of unexpected costs than a unit in a recently built or recently renovated building.

Before committing to a purchase, reviewing the most recent annual general meeting minutes, the body corporate financial statements and the sinking fund balance provides visibility over planned and likely future expenditure. A building with a healthy sinking fund and no deferred maintenance is a lower-risk investment than a building with minimal reserves and a history of special levies.

For self-employed borrowers, an unexpected special levy of $15,000 in the same year as a lower-than-expected business profit can create cash flow pressure that affects loan serviceability on other commitments. Selecting a property with lower capital expenditure risk smooths cash flow and reduces the likelihood of financial stress.
