Variable Rate Investment Loans and Extra Repayments

Variable rate investment loans allow you to make extra repayments without penalty, but whether you should depends on your financial circumstances and what you're trying to achieve.

For property investors in Reservoir, where the median rental yield sits around 4.5%, the calculation involves more than just paying down debt faster. Extra repayments reduce your loan balance and deductible interest, which changes your tax outcome. At the same time, they build equity you can access later and reduce the interest you pay over time. The question becomes whether locking money into your investment property serves your broader strategy, or whether those funds create more value deployed elsewhere.

How Extra Repayments Change Your Deductible Interest

Extra repayments on an investment loan reduce the loan balance, which lowers the interest charged in future months. Because interest on investment property debt is tax deductible, this means you're reducing your claimable expenses. For someone on the 37% marginal tax rate, every $1,000 in interest you avoid costs you $370 in lost tax benefits.

Consider an investor who owns a two-bedroom unit near Edwardes Lake with a variable rate loan of $450,000 at a standard variable interest rate. Making an extra $10,000 repayment reduces the principal immediately. Over the following year, this saves approximately $400 in interest at current variable rates. However, that $400 saving also means $148 less in tax deductions. The net benefit is $252, which is still positive, but significantly smaller than the headline saving suggests.

This calculation shifts if your marginal tax rate increases or if you're in a phase where maximising deductions matters more than debt reduction. Some investors prefer to hold excess cash in an offset account linked to their owner-occupied loan instead, where the interest saved isn't tax deductible and therefore delivers the full benefit.

Accessing Funds After Making Extra Repayments

Most lenders allow you to redraw extra repayments made on a variable rate loan, but redrawing investment loan funds can create tax complications. If you redraw money and use it for non-investment purposes, the interest on that redrawn portion is no longer tax deductible. This is a common mistake that reduces your claimable expenses without any corresponding benefit.

As an example, an investor makes $20,000 in extra repayments on their Reservoir investment property loan over two years. They later redraw $15,000 to renovate their own home. The interest attributable to that $15,000 is now private purpose debt and cannot be claimed as a deduction against rental income. The Australian Taxation Office tracks the purpose of borrowed funds, not the security used, so even though the loan is secured against an investment property, the redrawn portion loses its deductibility.

If you anticipate needing access to cash in the near term, keeping those funds in an offset account or a separate savings buffer is often more tax effective than making extra repayments and redrawing later. This preserves the deductibility of your entire loan balance.

When Extra Repayments Support Portfolio Growth

Reducing your loan balance through extra repayments increases your equity position, which can improve your borrowing capacity when you're ready to acquire another property. Lenders assess your loan to value ratio (LVR) and serviceability when you apply to expand your property portfolio. A lower loan balance on your existing property strengthens both metrics.

For an investor holding a property in Reservoir's Broadway precinct, where values have appreciated steadily, paying down $30,000 on a $400,000 loan over three years reduces the LVR and demonstrates disciplined financial management. When applying for a second investment loan, that equity becomes accessible through refinancing or a top-up, without needing to sell.

The timing matters. If you're planning to buy another property within 12 to 18 months, directing surplus income toward extra repayments can position you more favourably with lenders. However, if your next purchase is five years away, those funds might deliver better returns invested elsewhere, particularly if you're in a high tax bracket where negative gearing benefits remain valuable.

Setting Up a Variable Rate Loan for Flexibility

When selecting a variable rate loan for buying your first investment property, confirm whether the product includes a redraw facility and whether there are limits on how much you can repay without restriction. Some lenders cap extra repayments at a certain threshold before treating them as a full discharge and recalculating fees.

You'll also want to understand the turnaround time for accessing redrawn funds. Some lenders process redraw requests within 24 hours through online banking, while others require a formal application that can take several days. For investors managing cash flow across multiple properties or dealing with unexpected maintenance costs like body corporate levies, this access speed can matter.

Variable rate investment loans typically offer more flexibility than fixed rate products, which often prohibit extra repayments beyond a small annual allowance. However, that flexibility only creates value if it aligns with how you manage your finances and whether you need the option to access those funds later without compromising your tax position.

We regularly help Reservoir investors structure their loans to support both immediate cash flow and longer-term growth objectives. Whether you're holding a single rental property or building a more substantial portfolio, the way you handle extra repayments affects your tax outcome, your equity position, and your ability to borrow again.
