Top Strategies to Buy Your First Investment Property

Buying your first investment property requires a different loan approach than buying a home to live in.

The loan structure you choose affects how much deposit you need, what tax deductions you can claim, and whether you can access government schemes. Most first-time investors underestimate the difference between owner-occupied and investment lending, particularly around serviceability and deposit requirements.

Why Investment Loans Have Different Serviceability Rules

Lenders assess investment loans at a higher interest rate buffer than owner-occupied loans. APRA requires all lenders to test your ability to service a loan at least 3.0 percentage points above the actual loan rate. For investment loans, many lenders add an additional buffer or apply stricter assessment policies because rental income is not guaranteed.

Consider a buyer looking to purchase an investment property in Oakleigh with rental income of $2,400 per month. Most lenders will assess only 80% of that rental income when calculating serviceability, even if the property has a strong rental history. That means the lender treats the rental income as $1,920 per month for serviceability purposes. If the buyer earns $95,000 per year and has $1,800 in monthly living expenses, the reduced rental income assessment directly impacts how much they can borrow. The buyer applied for pre-approval expecting to borrow $580,000 based on gross rental income, but the lender approved $520,000 once the 80% rental income shading and investment loan buffer were applied. The buyer adjusted their property search to match the approved borrowing capacity rather than stretching their deposit to cover the shortfall.

How Much Deposit You Need for an Investment Property

You need a minimum 10% deposit plus stamp duty and other purchase costs to buy an investment property. The Australian Government 5% Deposit Scheme and Help to Buy scheme are not available for investment purchases. If you have less than 20% deposit, you will pay Lenders Mortgage Insurance. LMI on investment loans is typically higher than on owner-occupied loans because lenders treat investment lending as higher risk.

For a property in Mount Waverley, stamp duty on an investment property valued at the suburb's current median would add a significant upfront cost. Buyers also need to budget for building and pest inspections, conveyancing fees, and loan establishment costs. In our experience, buyers who calculate their deposit based only on the property price often find themselves short by several thousand dollars when settlement approaches.

Using Equity from Your Owner-Occupied Home

If you already own a home, you may be able to use the equity in that property as a deposit for your first investment property. Equity is the difference between what your home is worth and what you owe on it. Most lenders will allow you to borrow up to 80% of your home's value without paying LMI, though some lenders offer higher limits for specific borrower profiles.

A buyer who owns a home in Glen Waverley valued at $900,000 with a remaining loan balance of $400,000 has $500,000 in equity. At 80% lending, the buyer can access $720,000 in total lending. After repaying the existing $400,000 loan, the buyer has $320,000 available. That amount covers a deposit and purchase costs on an investment property without needing to save additional cash. The buyer kept their owner-occupied loan separate from the new investment loan to maintain clear tax deductions. Releasing equity to purchase requires a valuation of your existing property and a full serviceability assessment that includes both the existing home loan and the new investment loan.

Choosing Between Variable, Fixed, or Split Rate Structures

Investment loans are available as variable rate, fixed rate, or a combination of both. Variable rates allow you to make extra repayments and access features like offset accounts, which can reduce the interest you pay. Fixed rates lock in your repayment amount for a set period, typically between one and five years, but usually come with limits on extra repayments and no offset account.

A split loan divides your borrowing between fixed and variable portions. You might fix 50% of the loan to protect against rate rises and keep 50% variable to maintain flexibility. For investment properties, variable or split structures are often more useful because they allow you to deposit rental income into an offset account and reduce interest costs without affecting your tax deductions.

Interest-Only Loans and When They Make Sense

Many investors choose an interest-only loan structure for the first few years. Interest-only repayments are lower than principal and interest repayments, which can help with cash flow if rental income does not fully cover your loan repayments and other property expenses. However, you are not paying down the loan balance during the interest-only period.

From a tax perspective, all interest charged on a loan used to purchase an investment property is generally deductible. Whether you choose interest-only or principal and interest repayments does not change the deductibility of the interest component. Interest-only loans revert to principal and interest repayments after the interest-only period ends, typically after five years, and your repayments will increase at that point.

Negative Gearing and What Changed in May 2026

Negative gearing allows you to deduct losses from your investment property against your other income, such as your salary. If your rental income is $28,000 per year and your property expenses including interest, rates, insurance, and maintenance total $35,000, you have a $7,000 loss that reduces your taxable income.

From the 2027-28 income year, losses on established investment properties purchased after 7:30pm AEST on 12 May 2026 can only be offset against other residential property income, not against salary or wages. Losses can be carried forward to offset property income in future years. Properties purchased before that date and new builds purchased after that date are not affected by this change. Buyers planning to purchase an established investment property should factor in that tax losses will not reduce their payable tax on employment income from the 2027-28 financial year onward.

Location Factors That Affect Borrowing and Returns

Lenders assess properties in regional areas differently to properties in established Melbourne suburbs. Some lenders apply higher interest rates or lower maximum LVR limits to properties in certain postcodes, particularly in regional towns with smaller populations or declining demographics. If you are considering an investment property outside metropolitan Melbourne, confirm with your broker that your preferred lender will accept that location at standard lending terms.

Melbourne suburbs close to transport, universities, and employment hubs tend to attract consistent rental demand. Suburbs like Box Hill, Clayton, and Glen Waverley have strong rental markets due to proximity to Monash University, hospitals, and train lines. Properties in these areas may achieve higher rental yields and more reliable tenancy rates, which supports serviceability when you apply for finance.

Stamp Duty and Why Investment Properties Pay More

Investment property buyers in Victoria pay stamp duty at standard rates without access to first home buyer concessions. Stamp duty is calculated on the purchase price and increases progressively. There is no cap or concession available for investment purchases, even if you have never owned property before.

For a property valued at $650,000, stamp duty in Victoria would be approximately $34,070. This is a significant upfront cost that must be paid at settlement and cannot be added to your loan in most cases. Some lenders offer stamp duty capitalisation, which allows you to borrow the stamp duty amount, but this increases your total loan size and may push your LVR above 80%, triggering LMI.

Tax Implications When You Eventually Sell

When you sell an investment property, you will pay capital gains tax on any profit. From 1 July 2027, capital gains on investment properties are calculated using cost base indexation rather than the 50% discount that previously applied. This means you index the purchase price of the property by inflation and pay tax only on gains above inflation. A minimum 30% tax rate applies to capital gains accruing from 1 July 2027 onward. Gains that accrued before that date are taxed under the previous rules. Properties classified as new builds at the time of purchase may allow you to choose between the old discount method and the new indexation method when you sell.

Why You Should Speak to a Broker Before You Start Searching

Getting pre-approval before you start searching gives you a clear borrowing limit and shows sellers and agents that you are a serious buyer. Pre-approval also identifies any serviceability issues or documentation gaps early, so you have time to address them before you find a property. Applying for a home loan as an investor involves additional documentation compared to owner-occupied applications, including rental appraisals and sometimes a statement of your investment strategy.

Brokers who work regularly with investors can also help structure your loans to separate investment and owner-occupied debt, preserve equity for future purchases, and set up offset accounts in a way that maximises your tax position. Loan structure is not something you can easily change after settlement without refinancing, so it is worth getting it right from the start.
