Everything You Need to Know About Investment Apartment Loans

Buying an investment apartment requires a different financing approach than your family home.

Lenders assess rental income, body corporate costs and vacancy periods differently, and the loan structures available reflect the reality that you're building wealth rather than housing yourself. Understanding how lenders view apartments specifically, and what loan features serve your goals, helps you secure appropriate finance without overpaying or accepting unnecessary restrictions.

How Lenders Assess Investment Apartment Finance

Lenders calculate your borrowing capacity by adding 80 per cent of expected rental income to your existing income, then testing repayments at a rate at least 3.0 percentage points above the actual loan rate. For apartments, they also deduct body corporate fees and apply a holding cost buffer to account for vacancy periods between tenants. A two-bedroom apartment in St Kilda with weekly rent around $550 and quarterly body corporate fees near $1,200 would add roughly $22,880 to your annual income for serviceability purposes, after the 20 per cent discount and body corporate deduction.

Lenders also assess the apartment itself. Most require a minimum internal floor area of 50 square metres and will reduce the maximum loan amount or decline finance entirely for studios or serviced apartments in transient buildings. If the building has commercial uses exceeding 50 per cent of total floor area, or if more than half the units are investor-held, some lenders impose lower loan to value ratios or charge higher rates.

Interest Only Repayments and Cash Flow Management

Interest only repayments reduce your monthly outgoings during the investment phase, preserving cash flow for other expenses or additional purchases. On a loan amount of $500,000, switching from principal and interest to interest only could reduce monthly repayments by $800 to $1,200 depending on the rate, giving you breathing room during vacancy periods or unexpected maintenance costs.

Most lenders offer interest only terms up to five years initially, with the option to extend or revert to principal and interest when the term expires. Choosing interest only does not prevent you from making extra repayments if your loan features include an offset or redraw facility. It simply removes the obligation to repay principal, which can be valuable when rental income fluctuates or when you're channelling surplus funds into your next deposit.

Variable or Fixed Rate for Investment Property

Variable rates allow you to make unlimited extra repayments and access offset accounts, which is particularly useful if you're holding cash for future purchases or managing irregular income. Fixed rates provide certainty over repayments for one to five years but typically restrict extra repayments to $10,000 to $30,000 per year and do not offer offset functionality during the fixed period.

Consider an investor holding an apartment in Docklands and planning to purchase a second property within two years. A variable rate loan with an offset account lets them park their next deposit in the offset, reducing interest on the existing loan while keeping funds accessible. If they fixed the rate instead, that deposit would sit in a savings account earning taxable interest rather than reducing non-deductible debt. The choice depends on whether rate certainty or flexibility matters more for your immediate plans.

Deposit and Borrowing Limits for Apartment Purchases

Most lenders require a 10 per cent deposit for investment property, though borrowing above 80 per cent of the property value attracts Lenders Mortgage Insurance. For apartments specifically, some lenders cap borrowing at 90 per cent loan to value ratio regardless of your deposit, particularly in buildings with known defects or high investor concentrations.

If you're using equity from your home rather than cash savings, the same principles apply. Lenders assess the combined loan to value ratio across all secured properties and apply the serviceability test to total debt. Releasing equity to fund your deposit does not avoid LMI if the combined borrowing exceeds 80 per cent of the total security value. Planning your deposit structure with someone who understands how lenders assess cross-collateralised security can prevent surprises during the application.

Negative Gearing and Proposed Tax Changes

Negative gearing allows you to offset rental losses against your other income, reducing your overall tax liability. For established apartments purchased before 12 May 2026, this treatment continues indefinitely under current law. For apartments purchased after that date, proposed changes intend to quarantine losses from 1 July 2027, meaning they would only be deductible against future rental income or capital gains rather than your salary or business income.

The changes are not yet law and require passage through Parliament. If you're considering an established apartment and concerned about tax treatment, speaking with a licensed tax adviser before committing helps you understand the potential impact on your cash flow and long-term returns. New build apartments retain full negative gearing benefits regardless of purchase date, which may influence your decision about property type.

Tax Deductions and Claimable Expenses on Investment Apartments

Beyond loan interest, you can claim body corporate fees, council and water rates, landlord insurance, property management fees, repairs and maintenance, and depreciation on the building and fixtures. For apartments, body corporate fees are often substantial and fully deductible, which can offset a significant portion of your holding costs.

Depreciation on newer apartments can return several thousand dollars per year in tax deductions without requiring any cash outlay. A quantity surveyor prepares a depreciation schedule, typically costing $600 to $800, which outlines the claimable amounts over time. Older apartments still attract depreciation on renovations and new fixtures like ovens, blinds and air conditioning units, though the building itself may be fully depreciated.

When Refinancing Makes Sense

Refinancing an investment loan can reduce your interest rate, release equity for further purchases, or switch your loan structure to better suit your current goals. If your apartment has increased in value or your income has grown, refinancing might allow you to access equity without selling, or to negotiate a better rate discount based on a lower loan to value ratio.

Refinancing also allows you to consolidate debt or move to a lender with more suitable investment loan options, particularly if your original lender has tightened policy around apartments or your building specifically. Reviewing your loan every two to three years, or when your fixed rate expires, ensures you're not paying more than necessary or missing features that support your next move.

Structuring Your Loan for Portfolio Growth

How you structure your first investment loan affects how readily you can borrow for the second. Keeping investment debt separate from owner-occupier debt, using offset accounts strategically, and maintaining clear records of rental income all make future applications more efficient.

Some investors use a line of credit secured against their home to fund deposits, then refinance each purchase onto its own standalone loan once settled. Others prefer to cross-collateralise properties to avoid LMI, though this can complicate future refinancing or sales. There is no universal structure, but understanding how your choices now will affect your borrowing capacity later helps you build a portfolio that supports your goals rather than constrains them.
