Beginner's guide to Investment Property Loans

Your shift income is stable, but it won't build passive income on its own.

Investment property finance is structured differently to owner-occupied lending. Lenders assess the rental income you'll receive, not just your salary. You'll need to show serviceability across both your current home loan and the proposed investment loan. Most lenders apply a vacancy rate assumption and discount the rental income by around 20% when calculating what you can borrow. The key difference is access to interest-only repayments and the ability to claim all borrowing costs as tax deductions.

How Lenders Assess Investment Loan Applications

Lenders calculate your borrowing capacity using your gross salary, rental income from the proposed property, and existing commitments. Rental income is discounted to account for periods when the property might be vacant or underperforming. Most lenders apply a discount of 20%, though some use 25% depending on the property type and location. If you're purchasing a unit with high body corporate fees, those ongoing costs are factored into the serviceability assessment as well.

Consider a paramedic earning a base salary plus regular shift penalties who wants to purchase a two-bedroom apartment generating rental income. The lender will include the salary and penalties as ongoing income, apply the rental discount, then subtract existing home loan repayments, car loans, and credit card limits. Even if you pay off your card each month, the full limit is counted as a potential liability. Reducing limits or clearing personal debt before applying can increase what you're approved to borrow.

Ambulance Victoria employees often have access to low deposit loans for owner-occupied purchases. Investment loans follow different criteria. Most lenders require a minimum 10% deposit, and some will lend up to 90% of the property value if you're willing to pay Lenders Mortgage Insurance. LMI on an investment loan protects the lender if you default, and the premium can often be capitalised into the loan amount rather than paid upfront.

Interest-Only Repayments and Cash Flow Management

Interest-only repayments mean you only pay the interest portion of the loan each month, not the principal. The loan balance stays the same, but your monthly repayment is lower. This structure is commonly used by property investors because it maximises cash flow and increases the tax deduction you can claim. All interest paid on an investment loan is deductible against your rental income, and if the property runs at a loss, that loss can offset your salary under negative gearing.

Interest-only periods typically last one to five years, after which the loan reverts to principal and interest unless you request an extension. If you hold the property long term and the capital value increases, the equity gain often outweighs the lack of principal reduction during the interest-only period. Speak to your accountant about whether this structure suits your tax position and investment horizon.

Some investors use a split loan structure, fixing part of the interest rate to lock in repayments and leaving the remainder on a variable rate with an offset account. This allows you to park surplus cash in the offset to reduce interest on the variable portion while maintaining flexibility. The fixed portion provides certainty, which can be useful if you're managing multiple properties or expect income to fluctuate.

Variable vs Fixed Investment Loan Rates

Variable rates move with the market and usually come with features like offset accounts, redraw facilities, and the ability to make extra repayments without penalty. Fixed rates lock in your repayment for a set term, typically one to five years, but limit your ability to pay down the loan early. If you break a fixed rate before the term ends, you may be charged break costs based on the difference between your fixed rate and the current wholesale rate.

For investment loans, variable rates are more common because they allow flexibility and the offset account can be used to manage cash flow across multiple properties. Some lenders offer a rate discount for investors who maintain a loan to value ratio below 80%, or who hold multiple loans with the same lender. Loyalty discounts and package deals are worth reviewing if you're planning to build a portfolio over time.

Negative Gearing and Tax Deductions After Budget Changes

Negative gearing allows you to claim a tax deduction when your rental property costs exceed the rental income it generates. Interest, property management fees, council rates, insurance, repairs, and depreciation are all claimable expenses. The net loss reduces your taxable income, which can result in a larger tax refund depending on your marginal tax rate.

Recent changes announced in the Federal Budget will affect properties purchased after 12 May 2026. If you buy an established residential property from 13 May 2026 onwards, losses will only be deductible against rental income or capital gains from residential property from 1 July 2027. Losses can no longer be claimed against your salary or wages. Excess losses can be carried forward to offset future residential property income, so deductions are deferred rather than lost entirely.

New builds remain incentivised under the revised rules. Investors purchasing newly constructed property can still choose between the 50% capital gains tax discount or the new indexed cost base method, whichever is more favourable. If you bought an established investment property before Budget night, your existing negative gearing and capital gains tax treatment is grandfathered under the old rules.

This changes the financial equation for purchasing established property. If you're looking at an older unit with strong rental demand, you'll need to factor in that any net loss can only offset future rental income or capital gains, not your current salary. In many cases, this extends the timeline to positive cash flow and shifts the focus toward properties that generate higher rental yields or have stronger capital growth prospects.

Borrowing Against Equity to Fund Your Deposit

If you already own a home, you can use the equity in that property to fund your investment deposit without selling or refinancing your existing loan. Equity is the difference between what your property is worth and what you owe on it. Most lenders allow you to borrow up to 80% of your home's value, or up to 90% if you pay LMI.

Consider a scenario where your home is valued at the current market rate and you owe a lower amount on the mortgage. The difference represents usable equity. A lender can provide an equity release loan secured against your home, which you then use as the deposit for the investment property. This keeps your owner-occupied loan separate from your investment loan, which simplifies tax reporting and allows you to claim all interest on the investment loan as a deduction.

Lenders assess serviceability across both loans, so you'll need to demonstrate that your income can support the combined repayments. If you're using equity and your combined loan to value ratio exceeds 80%, you'll pay LMI on the portion above that threshold. Some lenders offer discounted LMI for paramedics and emergency services workers, which can reduce the upfront cost of using equity to invest.

Structuring Loans Across Multiple Properties

Once you hold more than one investment property, loan structure becomes more important. Keeping each property on a separate loan allows you to sell or refinance individual assets without affecting the others. It also simplifies the tax treatment because each loan is clearly tied to a specific property.

Some investors use a line of credit or equity loan as a buffer to cover holding costs, renovations, or deposit top-ups for the next purchase. This can accelerate portfolio growth, but it increases your overall debt and needs to be managed carefully. Line of credit facilities usually have higher interest rates than standard investment loans, and they don't reduce over time unless you actively pay them down.

If you're planning to acquire multiple properties, work with a broker who understands portfolio lending. Some lenders will cap the number of investment loans they'll provide to a single borrower, or apply stricter serviceability tests once you hold more than two or three properties. Others specialise in investor lending and offer more flexible criteria for paramedics with stable employment.

What to Bring to Your Investment Loan Application

You'll need payslips covering the most recent three months, your employment contract, and recent tax returns if you've claimed rental income or deductions in previous years. If you're purchasing an investment property for the first time, the lender will estimate rental income based on a valuation or rental appraisal from a licensed property manager.

Lenders will also request details of existing loans, credit card limits, and any other ongoing financial commitments. If you're using equity from your home, a current valuation will be required to confirm how much you can borrow. Some lenders accept an automated valuation, while others require a physical inspection depending on the property type and location.

If you're purchasing a unit, the lender may request a copy of the body corporate financial statements to ensure the building is well maintained and there are no large special levies pending. High body corporate fees or low sinking fund balances can affect the lender's willingness to approve the loan or may result in a lower valuation.
