Purchasing an investment apartment in Bentleigh involves more than finding the right property and securing finance. The loan structure you choose affects your borrowing capacity, tax position and portfolio growth potential for years ahead.
Understanding Investment Loan Serviceability in Apartment Purchases
Lenders assess your ability to service an investment loan at an interest rate 3.0 percentage points above the product rate, and they apply a rental income discount of 20 per cent to account for vacancy and maintenance. Consider a scenario where a Bentleigh apartment generates rental income of $2,600 per month. The lender applies that income at 80 per cent, so $2,080 is used in the serviceability calculation. If your repayments on the proposed loan, calculated at the product rate plus the 3.0 percentage point buffer, exceed the rental income by a significant margin, the shortfall is added to your other commitments and tested against your salary. This is where many investors misjudge their capacity. The shortfall between what the property earns and what the loan costs, after both the rental discount and the buffer are applied, can be substantial.
Body corporate fees for Bentleigh apartments typically range from $3,000 to $6,000 per year depending on the age and amenities of the building. These fees are factored into your overall holding costs but are not treated as loan repayments by the lender. They do, however, reduce the net rental yield, which in turn affects how much income the property contributes to your serviceability position.
Deposit and LVR Requirements for Investor Apartment Purchases
Most lenders cap investor loans at 90 per cent LVR, though some will not lend above 80 per cent LVR for apartments in certain postcodes or buildings with fewer than six units. Lenders Mortgage Insurance is required when borrowing above 80 per cent LVR, and the premium increases sharply as the LVR rises. For an apartment purchased at the current median in Bentleigh, borrowing at 85 per cent LVR will incur an LMI premium that can reach several thousand dollars, capitalised into the loan or paid upfront.
If you already own property, you may be able to use equity rather than cash savings to fund the deposit. In practice, this means the lender takes a second mortgage over your existing property to cover the deposit and costs on the new purchase. The combined LVR across both properties must still fall within the lender's policy, and the total borrowing is tested against your income using the same serviceability buffer. We regularly see investors assume that equity release solves the deposit question without considering that it increases the total debt tested at the buffered rate.
Interest Only Repayments and Cash Flow Management
Interest only repayments are a common feature of investment property finance. The repayment is lower than a principal and interest loan, which improves cash flow and can increase your borrowing capacity when the lender assesses your next purchase. Interest only periods are typically offered for one to five years, after which the loan reverts to principal and interest unless you request an extension or refinance.

Under current tax law, the interest paid on an investment loan is deductible against rental income and, if the property is negatively geared, the loss can be offset against your other income. For properties acquired before 12 May 2026, this treatment continues indefinitely. For established apartments purchased after that date, losses from the 2027-28 income year onward can only be offset against other residential property income. New build apartments purchased after 12 May 2026 retain full negative gearing treatment. Bentleigh has a limited supply of new apartment stock, so most purchases in the area will be established properties subject to the quarantining rule.
Fixed or Variable Rate Investment Loans
A variable rate investment loan allows you to make extra repayments, access offset accounts and redraw surplus funds without penalty. A fixed rate provides repayment certainty for a set term but generally does not permit extra repayments beyond a small annual threshold, and offset accounts are rarely available. Some investors split their loan between fixed and variable to manage both rate risk and flexibility.
Rate discounts on investment loans are typically smaller than those offered on owner-occupied loans. The difference reflects the higher risk weight that lenders assign to investor lending under prudential standards. When comparing loan products, focus on the comparison rate rather than the headline rate, as it captures most fees and gives a clearer picture of the total cost over time.
Debt to Income Limits and Portfolio Lending
From February 2026, lenders are restricted to lending no more than 20 per cent of their investor loan book to borrowers with a debt to income ratio of six times or more. If your total borrowings, including the new investment loan, exceed six times your gross annual income, your application may be declined or delayed even if your serviceability is sound. The limit applies separately to investor and owner-occupier lending, and it is measured across each lender's portfolio on a quarterly basis. In our experience, this has tightened lending appetite for investors with multiple properties or high existing debt levels, particularly in the second and third months of each calendar quarter when lenders approach their allocation.
Bentleigh's proximity to Southland Shopping Centre, Bentleigh railway station and the Centre Road retail and dining precinct supports tenant demand, particularly among young professionals and downsizers. Vacancy rates in the area remain low relative to outer suburbs, which lenders view favourably when assessing rental income assumptions. However, lending policy for apartments can vary significantly between institutions, with some lenders requiring a minimum of six units in the block and others applying postcode-based LVR caps. This makes the choice of lender as important as the choice of property.

Frequently Asked Questions
What deposit do I need to buy an investment apartment in Bentleigh?
Most lenders require a minimum 10 per cent deposit plus costs for investor apartment purchases, though some cap lending at 80 per cent LVR depending on the building size and location. If you borrow above 80 per cent LVR, Lenders Mortgage Insurance will apply.
How do lenders assess rental income on an investment property?
Lenders apply rental income at 80 per cent of the actual or market rent to account for vacancy and maintenance costs. They also assess your loan serviceability at a rate 3.0 percentage points above the product rate.
Can I still negatively gear an investment apartment purchased in Bentleigh?
Yes, but the treatment depends on when you purchased. Properties acquired before 12 May 2026 retain full negative gearing. Established apartments purchased after that date can only offset losses against other residential property income from the 2027-28 income year onward.
What is the debt to income limit for investment loans?
From February 2026, lenders can allocate no more than 20 per cent of new investor loans to borrowers with a debt to income ratio of six times or more. This applies across each lender's portfolio and may affect approval if your total debt is high relative to your income.
Should I choose a fixed or variable rate for an investment loan?
Variable rates offer flexibility for extra repayments and offset accounts, while fixed rates provide repayment certainty. Many investors use a split loan structure to balance both objectives.
