Do you know how investment loans actually work?

Investment loans work differently to owner-occupied home loans because the property generates rental income and offers different tax treatment.

If you're weighing up whether to buy an investment property in or around Malvern, the loan structure you choose affects everything from your cash flow to your long-term tax position. The fundamentals matter more than ever given recent changes to negative gearing and capital gains tax that apply to properties purchased after Budget night in May this year.

What Makes an Investment Loan Different

An investment loan is specifically for purchasing property you intend to rent out rather than live in. Lenders assess these applications differently because they factor in projected rental income alongside your personal income. The interest rate is typically slightly higher than owner-occupied loans, often by around 0.1% to 0.3%, because lenders view investment lending as carrying marginally more risk.

Your borrowing capacity increases when lenders include expected rent, though they don't count the full amount. Most lenders apply a shading rate of around 80%, meaning if a property in Malvern East generates $600 per week in rent, the lender might only count $480 towards your income assessment. They also factor in vacancy periods and holding costs, which is why the rental yield matters when you're determining how much you can borrow.

Interest Only vs Principal and Interest Repayments

Most property investors choose interest-only repayments for the initial period, typically between one and five years. This keeps monthly repayments lower and maximises your tax deductions, since the full loan balance remains outstanding and generates deductible interest. After the interest-only period ends, the loan reverts to principal and interest unless you renegotiate.

Consider someone purchasing a two-bedroom apartment near Malvern station with a 20% deposit. On an interest-only loan, they're only paying the interest portion each month, which improves cash flow and allows them to claim the entire interest component as a deduction against rental income. Once the property appreciates or their income increases, they might switch to principal and interest repayments to reduce debt, or they might refinance to extend the interest-only term and use the freed-up cash flow to fund another deposit.

Principal and interest repayments suit investors focused on debt reduction or those closer to retirement who want to own the property outright. The repayments are higher, but equity builds faster, and you're not reliant on refinancing every few years to maintain cash flow.

Fixed Rate or Variable Rate for Investment Properties

Variable rates give you flexibility to make extra repayments or access features like offset accounts, though genuine offset accounts on investment loans are less common than on owner-occupied loans. Fixed rates lock in your repayment amount for a set period, which helps with budgeting but usually comes with restrictions on extra repayments and no offset access.

Some investors split their loan between fixed and variable. This approach provides partial certainty on repayments while still allowing access to flexible features on the variable portion. It also spreads your risk if rates move significantly in either direction. The choice depends on your risk tolerance, your cash flow needs, and whether you plan to pay down the loan or hold it long-term while building equity.

How Negative Gearing Works After the Budget Changes

Negative gearing allows you to claim the loss from your investment property against your other income when your rental income doesn't cover your holding costs. If your property costs $40,000 per year to hold including interest, body corporate fees, rates, and insurance, but only generates $35,000 in rent, the $5,000 shortfall reduces your taxable income from your salary.

From 1 July 2027, this only applies to properties purchased before 13 May 2026. If you buy an established residential property after that date, losses can only be offset against rental income or capital gains from residential property, not against your wage income. The losses carry forward, so they're not lost, but the immediate tax benefit disappears. New builds remain fully deductible regardless of when you purchase, which is why the government is steering investors toward new construction.

This doesn't affect commercial property or shares, and it doesn't change the rules for properties you already own. If you purchased an investment unit in Carnegie or Camberwell before Budget night, your negative gearing deductions continue as they always have.

Loan to Value Ratio and Lenders Mortgage Insurance

Your deposit size determines your loan to value ratio, and most lenders will lend up to 90% of the property value for investment purposes, though 80% is more common to avoid Lenders Mortgage Insurance. LMI protects the lender if you default, and while it's a one-off cost that can be capitalised into the loan, it's also tax-deductible for investment properties.

A 20% deposit on a property valued at the Malvern median puts you at an 80% LVR, which avoids LMI and typically qualifies you for stronger interest rate discounts. If you're using equity from your home in Malvern to fund the deposit, lenders assess the combined loan amount across both properties, and your family home often stays on owner-occupied rates while the investment loan sits at investor rates.

Some lenders allow you to borrow up to 95% if you're a professional or high-income earner, though this usually requires genuine savings and a strong servicing position. The higher your LVR, the more scrutiny your application receives, particularly around rental income assumptions and your ability to service the debt if the property sits vacant.

Tax Deductions and Claimable Expenses

Interest on your investment loan is fully deductible, as are council rates, water charges, property management fees, insurance, repairs, and body corporate fees if you own an apartment. Depreciation on the building and fixtures adds another layer of deductions, particularly for newer properties, though recent budgets have limited depreciation claims on second-hand assets like appliances and carpets.

Stamp duty and legal fees aren't immediately deductible but form part of your cost base when calculating capital gains tax. Loan establishment fees and ongoing account-keeping fees are deductible in the year they're incurred. If you travel to inspect the property or meet with your property manager, those costs are generally claimable as well, provided the travel is directly related to earning rental income.

Keeping your investment loan separate from any personal borrowing is essential. If you refinance and blend your investment debt with owner-occupied debt, you lose the ability to clearly delineate which interest is deductible. This is why many investors maintain their investment loans independently, even if it means managing multiple facilities.

Capital Gains Tax from 1 July 2027

Under the previous rules, investors paid tax on 50% of their capital gain after holding the property for at least 12 months. From 1 July 2027, this changes to a minimum 30% tax on gains, with indexation applied to your cost base to account for inflation. Only gains that arise after 1 July 2027 are affected, so if you bought a property years ago, the gain up to that date is still calculated under the old rules.

Investors purchasing new builds can choose between the 50% discount and the new indexed approach, whichever delivers the lower tax outcome. Established properties purchased after Budget night are locked into the new system. The main residence exemption remains unchanged, so if you later move into the property and make it your primary residence, different rules apply.

Anyone receiving income support, including the Age Pension, is exempt from the minimum 30% tax, which provides some protection for retirees holding investment properties as part of their retirement strategy.

Using Equity to Build a Portfolio

Once your first investment property increases in value, you can access that equity to fund a deposit on a second property without selling. Lenders typically allow you to borrow against up to 80% of the property's current value, meaning if your Malvern investment has grown in value, the difference between what you owe and 80% of the new valuation becomes usable equity.

This approach accelerates portfolio growth but also increases your overall debt and servicing requirements. Lenders assess your ability to service all loans combined, so your income, existing debts, and rental income across all properties determine how much further you can borrow. In practice, most investors hit a serviceability ceiling after two or three properties unless their income increases or they pay down debt between purchases.

Refinancing an existing investment loan to access equity or secure more favourable loan features is common as your portfolio matures. Rate discounts improve as your total borrowing increases, and consolidating your loans with one lender can sometimes unlock better pricing or streamlined approval processes for future purchases.

Choosing the Right Loan Structure for Your Strategy

Your loan structure should reflect whether you're focused on capital growth, cash flow, or building equity. Interest-only loans suit investors prioritising growth and tax efficiency, while principal and interest suits those wanting to reduce debt over time. Splitting your loan between fixed and variable can provide a middle ground, though it adds complexity when refinancing.

If you're planning to build a portfolio, keeping your loans flexible is valuable. Avoid locking yourself into fixed rates with high break costs or products that penalise you for accessing equity. Some lenders offer investment loan packages with fee waivers, rate discounts, and the ability to link offset accounts, though these are less common on pure investment products compared to home loans.

Working with a mortgage broker in Malvern gives you access to a wider range of lenders and loan products than going directly to a single bank. Different lenders have different appetites for investment lending, and some specialise in portfolio investors or high LVR lending. Getting your structure right from the start saves you time and money later, particularly if you're planning to scale beyond one property.
