Investment Loans for Apartments: What You Need to Know

Buying an investment apartment on a single income is absolutely doable.

The concern most first-time property investors have is whether they can borrow enough on one salary to make the numbers work. With the right structure and realistic expectations about which apartments lenders favour, you can position yourself to access investment loan options that fit your circumstances. The key is understanding how lenders assess rental income and why some apartments qualify for better rates than others.

How Lenders Calculate Your Investment Loan Amount

Lenders typically add 80% of your expected rental income to your gross income when calculating how much you can borrow. Consider someone earning $75,000 annually who wants to purchase a two-bedroom apartment in Footscray for $450,000. If the property generates $450 per week in rent (about $23,400 annually), the lender adds roughly $18,720 to the borrowing calculation. That rental contribution helps offset the new loan repayments and increases borrowing capacity.

The actual loan amount you can access depends heavily on your other commitments. Credit cards, car loans, and existing debts all reduce what you can borrow. In our experience, reducing your credit card limit before applying makes a measurable difference to what lenders will approve, sometimes $30,000 to $50,000 more in borrowing power.

Your deposit also shapes the loan structure. With a 10% deposit plus costs, you'll typically pay Lenders Mortgage Insurance (LMI), which gets added to your loan amount. With 20% or more, you avoid LMI entirely and often access better investor interest rates.

Interest Only Investment Loans and Why They Matter

Most property investors choose interest only repayments for the first five years of their investment loan. You're only paying the interest each month, not reducing the loan amount itself.

This keeps your monthly repayments lower, which improves your cash flow and maximises tax deductions. The entire interest payment is typically tax deductible when you're earning rental income, whereas principal repayments are not. From a tax perspective, interest only loans let you claim more against your taxable income each year.

For someone on a single income, this structure can mean the difference between the property generating negative cash flow of $100 per week versus $200 per week. After claiming those losses against your tax return through negative gearing benefits, the actual out-of-pocket cost reduces further.

After the interest only period ends, the loan converts to principal and interest repayments unless you request an extension. Many investors refinance their investment loan at that point to secure another interest only period or to access equity for portfolio growth.

Why Apartments in Certain Buildings Get Rejected

Lenders assess apartments differently than houses, and not all apartment buildings qualify for standard investment loan products.

If more than 50% of an apartment complex is owned by one entity, or if the building hasn't reached a certain level of sold settlements, most major lenders won't touch it. Apartments with significant commercial space on the ground floor, or buildings where short-term rental platforms dominate, also face lending restrictions.

Body corporate issues matter too. Buildings with active legal disputes, major structural defects, or inadequate sinking funds can be declined outright. Lenders want confidence that the property will hold its value and remain insurable. Older apartments, particularly those built before certain building standards changed, sometimes face higher interest rates or lower loan to value ratio (LVR) limits.

One-bedroom apartments under 50 square metres are harder to finance, especially in areas where vacancy rates are high. Lenders know these properties have a narrower pool of potential tenants and can be harder to sell if you default. Some lenders cap their exposure to small apartments entirely, meaning your investment loan options shrink before you even start comparing rates.

If you're looking at an apartment in Melbourne's inner suburbs like Southbank or Docklands, where oversupply has been an issue in certain precincts, understanding which buildings lenders will actually approve becomes critical. Not every apartment listed for sale will qualify for finance, regardless of how much deposit you have.

Variable Rate or Fixed Rate for Investment Loans

Most investors opt for a variable rate on their investment property finance, or they split the loan between variable and fixed.

Variable rates give you flexibility to make extra repayments without penalty, to redraw funds if needed, and to refinance without break costs. They also tend to come with offset accounts, which let you park savings against the loan balance and reduce the interest charged. For single-income buyers, that flexibility can be valuable if your circumstances change or if you want to access equity later for a second property.

Fixed rates lock in your repayment amount for one to five years, which helps with budgeting and protects you if rates rise. The downside is limited flexibility and potential break costs if you need to exit the loan early. Fixed rates on investment loans are typically slightly higher than owner-occupied fixed rates, and you usually can't make extra repayments above a small annual cap.

Many investors split their loan, fixing half and leaving half variable. This balances certainty with flexibility. You can use the loan repayment calculator to model different scenarios and see how rate changes affect your cash flow.

Stamp Duty and Claimable Expenses That Add Up

Stamp duty on investment properties is one of the largest upfront costs and catches many first-time investors off guard. In Victoria, stamp duty on a $450,000 apartment is around $21,970. Unlike first home buyers, investors don't get concessions or exemptions, so this cost needs to come from your savings or be borrowed as part of the loan if your deposit allows.

Once you own the property, a range of expenses become claimable against your rental income. Interest, body corporate fees, council rates, property management fees, repairs, and depreciation on fixtures and fittings all reduce your taxable income. Even the cost of travelling to inspect the property can be claimed in some circumstances.

These deductions are what make negative gearing work. You might be losing $150 per week after rent and expenses, but after claiming those losses at tax time, your actual cost drops to $80 or $90 per week depending on your marginal tax rate. That's what we mean when we talk about building wealth through property while managing cash flow on a single income.

Accessing Equity After Your First Purchase

Once your investment apartment increases in value or you've paid down some of the loan, you can leverage equity to fund your next purchase. Lenders will typically let you borrow up to 80% of the property's current value without paying LMI again.

If your Footscray apartment was worth $450,000 when you bought it and it's now valued at $500,000, you have access to around $50,000 in usable equity after accounting for the loan balance and the 80% LVR limit. That equity can become the deposit for your next investment property or even help you get into your own home.

This is where buying your first investment property becomes a stepping stone rather than the end goal. Many people on a single income find it easier to save a deposit and borrow for an investment property first, then use the equity and increased borrowing capacity to purchase their home later. For others, the investment property becomes part of a long-term portfolio growth strategy focused on financial freedom and passive income.

The timing of when you can access that equity depends on your lender's policy and how much the property has appreciated. Some investors wait two years, others move sooner if the market has been strong. Working with a broker who understands equity release structures means you're not waiting unnecessarily or paying for valuations before you're ready.
