Smart ways to approach investment apartment loans

Buying an apartment as a rental property changes the lending conversation

Lenders treat investment apartment purchases differently to owner-occupied houses, and you will need a larger deposit and meet stricter serviceability tests. Most lenders require a minimum 10 per cent deposit plus costs for investment property purchases, but many prefer 20 per cent to avoid Lenders Mortgage Insurance. Apartments also attract higher interest rates than houses in most lender pricing models, and older apartments or those in high-density buildings can trigger stricter lending policies or valuation discounts.

You are borrowing against a property you will not live in, so the lender assesses your ability to service the loan differently. They will include rental income in your borrowing calculation, but they discount it by around 20 per cent to account for vacancy and maintenance. That means if the apartment is advertised at $500 per week, the lender will assess your income at roughly $400 per week. On top of that, they must test your ability to service the loan at an interest rate at least 3 percentage points above the actual rate, and debt-to-income limits mean you cannot borrow more than six times your annual income unless you fall within a narrow exception band.

Consider a buyer earning $95,000 per year who wants to purchase a one-bedroom apartment in an inner-city Melbourne suburb as an investment. With $70,000 saved and a clean credit record, they approach a lender for a loan of $550,000. The apartment is expected to rent for $450 per week. After applying the rental discount, the lender calculates the borrower's total annual income at roughly $113,700, and the loan amount represents a debt-to-income ratio just over 4.8. The borrower clears the DTI limit comfortably, but the lender still needs to confirm that the borrower can service the loan at the assessment rate. With existing personal expenses, a car loan and the new investment loan repayment calculated at the buffer rate, the borrower's residual income sits above the lender's minimum threshold. The loan is approved with a variable rate and an offset account, and the borrower structures the loan as principal and interest to maximise flexibility for future refinancing or portfolio expansion.

How lenders assess rental income and vacancy

Lenders apply a rental income reduction, usually around 20 per cent, when calculating your borrowing capacity for an investment apartment loan. This adjustment covers potential vacancy periods, tenant turnover and ongoing maintenance costs. If you are relying on rental income to support the loan serviceability, the reduction can have a material impact on how much you can borrow.

Some lenders accept a lower discount if you provide a signed lease agreement at settlement, but most apply the standard reduction regardless. In buildings with higher vacancy rates or in areas where rental demand fluctuates, some lenders may apply a higher discount or request additional buffer in your income. Body corporate fees, which are common with apartments, are also deducted as an ongoing expense in the serviceability calculation, and older buildings with higher levies can reduce your borrowing power more than you expect.

Interest-only or principal and interest for an investment apartment

Interest-only repayments keep your monthly outgoings lower and can improve cash flow, particularly if you are negatively geared and relying on tax deductions to offset the holding cost. Most lenders offer interest-only periods of up to five years on investment loans, after which the loan converts to principal and interest unless you apply to extend the interest-only term.

Principal and interest repayments reduce your loan balance over time and build equity, which can be useful if you plan to leverage equity for future property purchases or want the option to refinance without needing another deposit. For an apartment in a building with higher body corporate fees or lower capital growth potential, paying down the principal may give you more flexibility down the track. We regularly see investors choose principal and interest on their first investment loan and then move to interest-only once they have built a buffer or are purchasing a second property.

Variable or fixed rate for rental property loans

Variable rates give you full access to offset accounts, which can reduce the interest you pay on the loan if you park savings or rental income in the account. Offset accounts are particularly useful for investors who want to retain liquidity while reducing their taxable interest expense. Variable rates also allow unlimited extra repayments and penalty-free exit if you decide to sell or refinance.

Fixed rates lock in your repayment for a set term, usually between one and five years, and protect you from rate rises during that period. The trade-off is that you lose access to offset accounts on the fixed portion, and most lenders cap extra repayments at $10,000 to $30,000 per year. If you break a fixed loan before the term ends, you may face break costs. Some investors split their loan between variable and fixed to keep some offset access while locking in part of the rate.

Loan structure and tax deductions for property investors

Interest on your investment loan is tax deductible against rental income and other income under current rules, provided the loan is used to purchase or hold the rental property. To maximise the deduction, keep the investment loan separate from your owner-occupied loan or personal borrowings. If you redraw funds from the investment loan for private use, that portion of the interest is no longer deductible.

Body corporate fees, council rates, landlord insurance, property management fees and depreciation on fixtures and fittings are also claimable expenses. From the 2027-28 income year, new tax rules will limit how losses from established investment properties purchased after 12 May 2026 can be claimed. Losses will only offset income from other residential properties, not your salary, although you can carry forward unused losses. Properties defined as eligible new builds and properties you held or had under contract by 12 May 2026 are exempt from the change. If you are purchasing an established apartment after that date, the change affects how you should model your cash flow and holding strategy. Properties acquired before 30 June 2027 can still be negatively geared under the old rules for that financial year, but the new rules apply from 1 July 2027 onward.

What lenders look for in an apartment security

Lenders assess apartments on size, age, location and building type. Most lenders have a minimum apartment size, usually around 40 to 50 square metres, and some will not lend on studios at all. Apartments in high-rise buildings with more than four or five levels often require additional documentation, including a building report and confirmation of fire safety compliance. Buildings with a high proportion of short-term rental or serviced apartment units may be restricted by some lenders or require a higher deposit.

Older apartments, particularly those built before the 1990s, may be valued more conservatively or flagged for further inspection if the building shows signs of deferred maintenance or structural issues. Lenders will also review the body corporate financial statements to check for large upcoming levies or deficit budgets. If the body corporate has insufficient funds or a history of special levies, some lenders will reduce the valuation or decline the loan altogether. When comparing investment loan options, it pays to know whether your apartment fits the lender's security criteria before you make an offer.

Deposits, Lenders Mortgage Insurance and upfront costs

A 20 per cent deposit avoids LMI on most investment loans, but you can borrow with as little as 10 per cent if you are prepared to pay the insurance premium. LMI on a $550,000 loan with a 10 per cent deposit typically costs between $15,000 and $25,000, depending on the lender and your credit profile. The premium can be added to the loan amount, but that increases your LVR further and your ongoing repayments.

Stamp duty on investment property purchases in Victoria is calculated at the standard rate, which for a $600,000 apartment is roughly $31,000. If you are a foreign buyer, an additional 8 per cent surcharge applies, and you also pay annual land tax at the foreign owner surcharge rate. Settlement costs, including conveyancing, building and pest inspection, body corporate certificate and lender fees, usually add another $3,000 to $5,000. If you are borrowing close to your limit, you need to budget for all of these upfront costs in addition to your deposit.

When to refinance an investment apartment loan

Refinancing an investment property loan can reduce your interest rate, release equity for another purchase, or shift from interest-only to principal and interest as your circumstances change. If your original loan was written at a higher LVR and you have since paid down the balance or the property has increased in value, you may now qualify for a lower rate or access better loan features.

Some investors refinance to consolidate debt or restructure their loans when purchasing a second property. Others refinance to move from a fixed rate that is about to expire or to take advantage of offset accounts they did not have access to under their original loan structure. If you are considering a loan health check, bring your most recent loan statements, rental income records and a current body corporate fee schedule so we can model your options accurately.

Buying an investment apartment involves more than finding a property with strong rental yield. The loan structure, deposit size, interest rate type and tax treatment all shape your cash flow and long-term return.
