Fixed Rate Investment Loans: What They Lock In

A fixed rate investment loan locks your interest rate for a set period, typically between one and five years. This certainty matters most when rental income forms part of your serviceability calculation and rate rises could push repayments beyond what your tenant pays.

For property investors in Ormond, where the median rent for a two-bedroom unit sits around $450 to $520 per week, a sudden increase in variable interest rates can turn a manageable negative gearing position into a cash flow concern. Fixing the rate removes that risk for the locked period, though it also removes your ability to benefit if rates fall or to access offset accounts in most cases.

How Fixed Rates Affect Investment Loan Structuring

Fixed rate investment loans typically come with interest-only payment options, allowing you to minimise cash outflow while holding the property. When you fix the rate on an interest-only loan, you establish the exact repayment amount for the fixed term regardless of Reserve Bank movements.

Consider an investor who purchases a two-bedroom apartment in one of the brick walk-ups near North Road for $680,000 with a 20% deposit. The investment loan amount sits at $544,000. On an interest-only basis with a fixed rate, the monthly repayment remains constant for the duration of the fixed term. If rental income covers 70% of that repayment, the investor knows precisely what contribution from personal income is required each month for the next three or five years.

This certainty becomes valuable when structuring multiple properties or planning portfolio growth. Lenders assess your ability to service existing debt when approving additional investment loans. Fixed repayments provide clearer serviceability calculations than variable loans where buffer rates apply.

The Trade-Off Between Certainty and Flexibility

Fixed rate products limit your ability to make additional repayments without incurring break costs. Most lenders cap extra repayments on fixed investment loans at $10,000 to $30,000 per year. If you sell the property or want to refinance during the fixed period, break costs can run into thousands of dollars depending on rate movements.

Those restrictions matter less if your investment strategy relies on interest-only periods and minimal principal reduction. Many investors holding properties in established suburbs like Ormond plan to retain them for capital growth rather than paying down the loan quickly. For that approach, the repayment restrictions on a fixed loan align with the intended strategy.

Variable rate loans, by contrast, typically offer full offset account functionality and unlimited additional repayments. If your investment property sits vacant for a period and you want to park surplus cash against the loan to reduce interest, a variable structure accommodates that. Fixed loans generally don't include offset accounts, meaning any surplus cash earns taxable interest in a savings account rather than reducing non-deductible interest on your home loan.

When Ormond Investors Choose Fixed Rates

Investors purchasing in areas with established rental demand often fix when they anticipate rate increases but want to hold the property through a full market cycle. Ormond's proximity to Caulfield Racecourse, Monash University's Caulfield campus, and the Frankston line makes it appealing to young professionals and postgraduate students. That tenant profile usually maintains stable occupancy, reducing the risk that you'll need to dip into savings during a vacancy.

If you purchase an investment property with rental income forming a significant part of your borrowing capacity, fixing the rate prevents a scenario where rising rates reduce your ability to service the loan on paper even though the tenant continues paying rent. Lenders assess investment loans at a buffer rate above the actual rate, typically adding 2.5% to 3% to the loan rate when calculating serviceability. A fixed loan at least removes the underlying rate as a moving variable during the fixed term.

In our experience, investors also fix rates when they plan to draw equity from their owner-occupied property to fund the deposit. If you've used equity release to fund the investment deposit and rates rise sharply, both your home loan and investment loan repayments increase simultaneously on variable structures. Fixing one of those loans limits your total exposure.

Split Rate Structures for Investment Properties

Some investors divide the loan amount between fixed and variable portions, typically splitting 50/50 or 60/40. This approach captures some certainty while retaining access to offset accounts and flexible repayments on the variable portion.

In a scenario like this, an investor with a $600,000 loan might fix $300,000 for three years and leave $300,000 on a variable rate with an offset account. If the property experiences a vacancy, surplus cash can sit in the offset against the variable portion. The fixed portion delivers a floor on repayments. The split structure also reduces potential break costs because only half the loan is locked if circumstances change.

The downside is increased complexity. You're managing two loan accounts with different terms, rates, and conditions. Some lenders charge two sets of fees. If you plan to build a portfolio across multiple properties, simpler structures on each loan often prove more manageable than intricate splits on every holding.

Rate Discount Retention When Fixing

When you fix an investment loan, any rate discount negotiated at origination typically doesn't carry through to the fixed rate in the same way it applies to variable rates. Lenders publish fixed rates as standalone figures rather than discounts off a standard variable rate. You might secure a 0.60% discount on a variable investment loan, but the fixed rate offered is simply the advertised fixed rate for your loan amount and loan to value ratio.

That structure means the decision to fix should be based on the absolute rate offered, not on preserving a discount. Some investors assume the discount they negotiated applies across all products with that lender, but fixed and variable pricing operates separately. When comparing fixed investment loan options across lenders, the rate itself matters more than the discount language used in marketing.

Property investors holding loans above 80% loan to value ratio should note that Lenders Mortgage Insurance applies to the total loan amount regardless of whether it's fixed or variable. The LMI premium is a one-off cost paid at settlement, not an ongoing charge, so fixing the rate after purchasing doesn't trigger additional LMI.

Fixed Rates and Tax Deductions on Investment Properties

Interest on investment loans remains tax deductible whether the loan is fixed or variable. The deduction is based on the interest paid during the financial year, which you claim as an expense against rental income. Fixing the rate makes the deduction amount predictable, which can assist with tax planning if you're managing multiple income streams or calculating provisional tax.

Other claimable expenses such as body corporate fees, property management costs, and depreciation continue as usual regardless of loan structure. The fixed rate simply determines one line item in your annual deduction calculation. If you're using negative gearing benefits as part of your investment strategy, knowing the exact interest cost each year can help forecast your tax position more accurately.

When the fixed term ends, most lenders automatically revert the loan to their standard variable rate unless you actively choose a new fixed term or refinance. That reversion rate is typically higher than the discounted variable rate you'd negotiate on a new loan, so treating the fixed rate expiry as a trigger to review your loan structure makes sense.

Whether a fixed rate investment loan suits your situation depends on your cash flow tolerance, portfolio plans, and view on rate movements. The structure delivers certainty at the cost of flexibility, which aligns with some strategies and conflicts with others.
