Proven Tips to Maximise Rental Yield on Investment Loans

What Rental Yield Actually Tells You About an Investment Property

Rental yield is the annual rent you collect as a percentage of the property's purchase price or current value. A property bought for $600,000 that rents for $500 per week generates a gross rental yield of around 4.3%. That figure tells you whether the property earns enough income to cover holding costs, or whether you'll be funding the shortfall from your own pocket each month.

Gross yield is calculated as (annual rent / property value) x 100. Net yield accounts for all the costs you can't avoid: council rates, body corporate fees, landlord insurance, property management, and maintenance. For most residential properties in Melbourne, net yield sits between 1% and 3% lower than the gross figure. If the property you're considering shows a gross yield below 4%, you'll almost certainly be negatively geared from day one.

Consider a first-time investor looking at a two-bedroom apartment in Clayton, close to Monash University. The property is listed at $580,000 and rents for $480 per week. Gross yield comes in at 4.3%. Once you deduct annual costs of around $8,000 for body corporate, $1,500 for council rates, $800 for landlord insurance, $2,500 for property management, and set aside $1,500 for maintenance, net yield drops to around 1.8%. That gap between rental income and total costs matters when you're structuring an investment loan that works for your cash flow over the long term.

How Lenders Assess Rental Income When Calculating Your Borrowing Capacity

Lenders don't use the full rental income when assessing how much you can borrow. Most apply a haircut of 20% to 30% to account for vacancy periods, maintenance costs, and rental management fees. If your property generates $25,000 in annual rent, the lender might only count $17,500 to $20,000 when calculating your serviceability.

That reduction affects how much you can borrow across your entire portfolio. If you're planning to buy a second investment property down the line, the rental income from your first property is shaded heavily, which reduces your future borrowing power. Lenders also apply a higher interest rate buffer when stress-testing investment loans, typically around 3% above the actual rate. The combination of rental income shading and a higher assessment rate means you'll qualify for a smaller loan amount on an investment property than you would for an owner-occupied home, even if the deposit and income are identical.

In our experience, investors who start with a higher-yielding property in an area with low vacancy rates preserve more borrowing capacity for future purchases. A property that generates strong rental income relative to its price gives you more room to expand your portfolio without hitting serviceability limits.

Interest-Only Loans and How They Affect Cash Flow and Tax Outcomes

An interest-only loan means your monthly repayments only cover the interest charged on the loan, not the principal balance. For a $500,000 loan at current variable rates, switching from principal and interest to interest-only can reduce your repayments by around $800 to $1,000 per month, depending on the rate.

That structure improves your cash flow in the short term, which matters if the property is negatively geared and you're covering a shortfall each month. It also maximises the interest portion of your repayments, which is fully tax-deductible on an investment property. The principal portion is not deductible, so paying down the loan during the interest-only period offers no immediate tax benefit.

Interest-only periods typically run for one to five years, after which the loan reverts to principal and interest unless you request an extension. Not all lenders allow multiple extensions, and some require evidence of a clear repayment strategy before approving an interest-only term. If you're planning to use an interest-only loan to manage cash flow while building equity elsewhere, make sure the lender's policy supports that approach over the timeframe you have in mind.

The Budget Changes to Negative Gearing and How They Apply to New Investors

From 1 July 2027, rental losses on established residential properties purchased after 12 May 2026 can only be offset against residential property income or capital gains, not against your salary or wage income. If you buy an established investment property now and it costs you $8,000 more per year than it earns in rent, you won't be able to claim that $8,000 loss against your other income once the changes take effect.

Those losses aren't lost entirely. They carry forward and can be used to reduce tax on future rental income or capital gains from residential property. But the immediate cash flow benefit of negative gearing disappears for new purchases of established properties.

New builds remain exempt. If you buy a newly constructed property, you can still claim rental losses against all income sources under the existing rules. That distinction makes new apartments and townhouses more attractive from a tax perspective, particularly if you're in a higher tax bracket and were relying on negative gearing to reduce your taxable income each year. Properties purchased before Budget night on 12 May 2026 are grandfathered under the old rules, so the changes don't apply retrospectively.

Capital Growth Versus Rental Yield and How to Balance Both

A property that delivers strong rental yield today might not grow in value as quickly as a property in a tightly held suburb with lower yields but higher demand. The choice between the two depends on whether you need income now or you're prepared to fund a shortfall in exchange for long-term capital growth.

Melbourne's inner and middle-ring suburbs typically offer lower gross yields, often between 3% and 4%, because property values are higher relative to rent. Outer suburbs and regional areas can deliver yields above 5%, but capital growth tends to be slower and more dependent on local infrastructure projects or population shifts.

Consider an investor comparing a $750,000 townhouse in Glen Waverley with a $450,000 unit in a regional Victorian town. The Glen Waverley property rents for $550 per week, generating a gross yield of 3.8%. The regional unit rents for $350 per week, delivering a gross yield of 4.0%. The regional property has a slightly higher yield, but Glen Waverley's proximity to Monash University, strong school zones, and established infrastructure make it more resilient during market downturns and more likely to appreciate over a ten to fifteen-year hold period. If your goal is to build wealth through property, growth often matters more than yield, particularly if you have the cash flow to carry a negatively geared property in the early years.

Fixed Versus Variable Rates and How Rate Type Affects Holding Costs

Fixing your investment loan locks in your repayments for a set period, which makes budgeting simpler if you're covering a monthly shortfall. Variable rates give you flexibility to make extra repayments, access offset or redraw facilities, and refinance without penalty, but your repayments move with rate changes.

Most investors hold a blend. You might fix 50% to 70% of the loan for certainty on the bulk of your repayments, and leave the rest variable to take advantage of any rate cuts or to maintain access to flexible features. Fixed rates don't always sit below variable rates, and locking in at the wrong point in the cycle can mean you're paying more than you need to for several years.

If you're planning to refinance your investment loan within the next two to three years to access equity or secure a lower rate, avoid fixing the entire balance. Break costs on fixed-rate loans can run into thousands of dollars if rates have fallen since you locked in, and those costs eat into any benefit you'd gain from refinancing.

Tax-Deductible Expenses You Can Claim and How Loan Structure Affects Deductions

Interest on an investment loan is fully tax-deductible, provided the loan is used solely to purchase or improve the investment property. If you refinance and draw down extra funds for personal use, that portion of the interest is not deductible. Lenders and accountants recommend keeping investment and personal borrowing in separate loan splits to maintain a clear deduction trail.

Other claimable expenses include property management fees, landlord insurance, council rates, water rates, body corporate fees, repairs and maintenance, and depreciation on the building and fixtures. Depreciation is a non-cash deduction that can add several thousand dollars to your annual tax return, particularly on newer properties. A quantity surveyor can prepare a depreciation schedule for around $600 to $800, and that report remains valid for the life of your ownership.

Capital improvements like renovations or extensions are not immediately deductible. They're added to the property's cost base and reduce your capital gains tax liability when you sell. Repairs that restore the property to its original condition are deductible in the year you incur the cost. The distinction matters when you're planning maintenance work or upgrades.

When to Refinance an Investment Loan to Improve Yield or Access Equity

Refinancing makes sense when you can secure a lower rate, access equity to fund another purchase, or switch to a lender with features that suit your current strategy. A rate reduction of 0.5% on a $500,000 loan saves you around $2,500 per year in interest, which improves your net yield and reduces the amount you're funding out of pocket each month.

Accessing equity to buy a second property is one of the most common reasons investors refinance. If your first property has increased in value and you've paid down some of the loan, you may have usable equity that can form the deposit for your next purchase. Lenders typically allow you to borrow up to 80% of the property's current value without paying Lenders Mortgage Insurance, so if your property is now worth $650,000 and your loan balance is $480,000, you could access around $40,000 in equity while staying under that threshold.

Refinancing also allows you to restructure your loan to separate investment and personal debt, consolidate multiple investment loans under one lender for simpler management, or move from interest-only back to principal and interest if your cash flow has improved and you want to start paying down the balance. If you're expanding your property portfolio, refinancing at the right time can unlock the equity you need without requiring new savings.
