Common Mistakes When Buying Your First Investment Property

Buying your first investment property feels like a big decision, and it is.

The difference between building wealth steadily and stretching yourself too thin often comes down to a handful of decisions made in the first few months. Understanding how lenders assess investment loans differently to owner-occupied finance, what the recent tax changes mean for your cashflow, and how to structure your loan to support future growth will put you ahead of most first-time investors.

What Makes Investment Loan Borrowing Different

Lenders assess investment loan applications using tighter serviceability measures than they do for owner-occupied home loans. They add a buffer of at least three percentage points to the interest rate when calculating whether you can afford the repayments, and they apply a discount to rental income, typically around 80 per cent, to account for vacancy and maintenance periods.

Consider a buyer who already owns in Elanora and wants to purchase a unit in Currumbin as a rental. The rental appraisal comes back at $600 per week. The lender will assess serviceability using $480 per week in rental income and will test the loan repayments at a rate three percentage points higher than the actual product rate. If the buyer's salary and the discounted rental income can cover existing commitments plus the buffered investment loan repayments, the application moves forward. If not, the loan amount needs to come down or the deposit needs to go up.

Debt-to-income limits also apply. Since February, lenders can only write a limited portion of their new investor lending to borrowers with debt exceeding six times their gross income. If you earn $100,000 and already have $400,000 in home loan debt, taking on another $250,000 investment loan puts you at 6.5 times income. Some lenders will decline that application outright. Others may approve it but at a higher rate or with a larger deposit requirement.

How the Deposit Requirement Changes Your Borrowing

Most lenders want at least a 10 per cent deposit for investment property, plus costs. A 20 per cent deposit avoids Lenders Mortgage Insurance, which on investment lending can add several thousand dollars to your upfront costs and cannot be claimed as a tax deduction.

If you are planning to use equity from your Elanora home to fund the deposit, the lender will also assess the combined loan-to-value ratio across both properties. Releasing equity usually means increasing the loan on your existing home, which in turn increases the repayments the lender tests you against. That can reduce how much you are able to borrow for the investment property itself.

In our experience, buyers often underestimate settlement costs. Stamp duty, legal fees, building and pest inspections, and lender fees add up quickly. If you are purchasing in Queensland, stamp duty on an investment property does not attract any concessions. You pay the full rate regardless of whether it is your first investment or your fifth.

Interest Rate Structure and Repayment Type

Investment loan interest rates sit higher than owner-occupied rates, typically by 0.30 to 0.60 percentage points depending on the lender and your loan-to-value ratio. Variable rate products give you flexibility to make extra repayments and access offset or redraw features, which can be useful if you want to pay down the loan faster or build a buffer for future purchases. Fixed rate products lock in your repayments for a set period, but break costs apply if you need to exit early.

Interest-only repayments are still available on investment loans and remain common. They reduce your monthly outlay, which can help with cashflow in the early years, but the loan balance does not reduce during the interest-only period. Once the interest-only term ends, usually after five years, repayments switch to principal and interest and increase substantially. Some investors prefer to start on principal and interest from the outset to build equity and reduce debt over time.

The choice depends on your goals. If you are planning to use equity for a second purchase within a few years, paying down the loan steadily might serve you better than maximising short-term cashflow.

How Negative Gearing Rules Changed in July 2027

For properties purchased before May last year, rental losses can still be offset against your salary or other income, reducing your tax payable. That arrangement is referred to as negative gearing and it has been a feature of Australian property investment for decades.

From July last year, properties acquired after mid-May can only offset rental losses against other residential rental income or carry those losses forward to offset future rental income or capital gains. You cannot claim them against your wage. The exception is newly constructed dwellings that add to housing supply. Those properties retain access to negative gearing under the old rules even if purchased now.

For a first-time investor in Elanora, this changes the numbers. If you are looking at an established unit in Currumbin or Palm Beach, expect to carry any rental shortfall yourself without immediate tax relief. If your loan repayments, body corporate fees, insurance, and council rates add up to more than the rent you receive, that gap comes out of your after-tax income. Over time, as rents rise and your loan balance reduces, the property may move into positive cashflow. Until then, you need enough buffer in your household budget to cover the shortfall each month.

If you are considering a new build or a property that increases the dwelling count on a site, the tax treatment is more favourable. Those properties allow you to offset losses against your salary as before, which can make them more viable in the early years despite sometimes carrying a higher purchase price.

Structuring Your Loan to Support Future Growth

How you structure your first investment loan affects what you can do next. If you load all your available equity into the deposit and borrow the minimum amount, you leave yourself with little room to access further funds for a second property or renovation without refinancing.

Many investors use a split loan structure, keeping their owner-occupied debt separate from their investment debt. This keeps the interest on the investment portion fully deductible and avoids mixed-purpose loans that require detailed apportionment if you later want to release equity or refinance. If you own your home in Elanora and plan to buy an investment property elsewhere, your broker can structure the loans so each property sits on its own facility, making future changes cleaner.

Some lenders offer better rates or features on refinancing than they do to new customers. If your circumstances change or you want to consolidate debt, keeping your loan structure clear from the start makes that process faster and less costly.

What Lenders Want to See in Your Application

Lenders assess your capacity to service the loan, the quality of the property as security, and your overall financial position. They want to see stable income, a clean credit history, and enough savings buffer to cover several months of repayments and holding costs if the property sits vacant.

If you are self-employed, most lenders require two years of tax returns and financials. If you have recently changed jobs or taken parental leave, some lenders will still consider your application but may apply additional conditions. Rental income from the new property is included in serviceability but, as mentioned earlier, at a discounted rate to reflect vacancy risk.

The property itself also matters. Lenders apply postcode-based restrictions and may reduce the loan-to-value ratio or decline lending altogether in areas they consider oversupplied or higher risk. Elanora and nearby southern Gold Coast suburbs are generally well regarded by lenders, but individual properties with unusual features, small land size, or very high body corporate fees can still trigger caution.

Buying your first investment property is a process that rewards preparation. Understanding how lenders assess your application, what the tax changes mean for your cashflow, and how to structure the loan to suit your longer-term goals will give you a much clearer path forward.
