Fixed rate investment loans restrict your ability to make extra repayments without triggering break costs.
Coomera has attracted steady investor interest over the past few years, driven by the suburb's position as a northern Gold Coast entry point with schools, shopping infrastructure and proximity to the M1. Property investors in the area regularly refinance or restructure loans to align with changing market conditions, and the question of whether to fix all or part of an investment loan comes up in most conversations about loan structure.
Fixed Rate Limits Apply to Investment Loans
Most lenders cap extra repayments on fixed rate investment loans at $10,000 to $30,000 per year without penalty. Any repayment above that threshold incurs a break cost, which is calculated based on the difference between your fixed rate and the lender's current wholesale funding cost for the remaining fixed term. If rates have risen since you fixed, the break cost is usually zero. If rates have fallen or remained flat, the break cost can be substantial.
Consider an investor who purchases a townhouse in Coomera and fixes the entire loan at a rate they believe is favourable. Twelve months later, they receive a large bonus or an inheritance and want to reduce the loan balance by $50,000. If the fixed rate product allows only $20,000 in additional repayments per year, the remaining $30,000 triggers a break cost that might reach several thousand dollars depending on the rate environment and remaining fixed term. That cost directly erodes the benefit of paying down the loan early.
Split Loan Structures Preserve Flexibility
A split loan divides your borrowing into two or more portions, typically one fixed and one variable. The variable portion accepts unlimited extra repayments without penalty, while the fixed portion provides rate certainty for a defined term. Investors who anticipate irregular cash flow, such as rental income from multiple properties or periodic distributions from a business, often split their investment loan to retain the option of reducing debt when surplus cash is available.
In our experience, investors in Coomera who hold multiple properties or run a business alongside their property portfolio benefit from keeping at least 40 to 50 per cent of the loan on a variable rate. The variable portion absorbs lump sum repayments without restriction, and any reduction in that balance flows through to lower interest charges immediately.

Interest Only Periods and Fixed Rates
Interest only investment loans allow you to service the loan by paying interest charges alone, with no requirement to reduce the principal during the interest only period. Many lenders offer interest only terms on both variable and fixed rate products. Fixing an interest only loan does not change the repayment restriction, it simply locks the interest rate for the fixed term.
If you fix an interest only loan and want to switch to principal and interest repayments before the fixed term ends, most lenders will accommodate that request without a break cost, provided the change does not involve a discharge or refinance. However, making principal repayments above any annual cap will still trigger break costs on a fixed loan, even if the loan was initially structured as interest only.
When Fixed Rates Make Sense for Investors
Fixed rates provide certainty in environments where rates are expected to rise or remain elevated. Investors who prefer predictable outgoings and do not plan to make extra repayments during the fixed term can lock in their interest cost and structure their cash flow around that fixed commitment.
Variable rates suit investors who want the flexibility to reduce debt quickly, refinance to access equity for further purchases, or take advantage of rate discounts that lenders periodically offer to retain clients. Variable rates also allow you to redraw any extra repayments if your circumstances change, whereas most fixed rate products do not offer redraw on additional payments made within the allowable cap.
Break Costs Are Forward Looking
Break costs compensate the lender for the economic loss it incurs when you repay a fixed loan early. The calculation compares your fixed rate to the lender's cost of funding a loan for the remaining fixed term. If your fixed rate is higher than the current cost of funds, the lender suffers no loss and the break cost is zero. If your rate is lower, the lender calculates the present value of the interest shortfall over the remaining term.
Break costs are not penalties in the regulatory sense. They are a contractual adjustment based on wholesale interest rate movements. The amount varies daily as market rates change, and most lenders will provide a break cost estimate on request before you commit to repaying or refinancing a fixed loan.
Structuring for Portfolio Growth
Investors who plan to acquire additional properties within a few years often avoid fixing the entire loan amount, because refinancing to access equity or consolidate debt during a fixed term usually triggers break costs. Keeping a portion of the loan variable allows you to leverage equity for further purchases without waiting for the fixed term to expire.
Coomera's proximity to employment hubs in both Brisbane and the northern Gold Coast has supported rental demand from young families and commuters. Investors in the suburb who intend to grow their portfolio typically structure loans with future refinancing in mind, rather than prioritising rate certainty across the entire balance.
Tax Treatment of Interest Does Not Change
Interest on investment loans remains deductible regardless of whether the loan is fixed or variable, provided the borrowing is used to acquire or hold the rental property. Break costs incurred when refinancing or repaying an investment loan early are not deductible as a borrowing expense. The ATO treats break costs as capital in nature, which means they do not reduce your assessable income in the year they are paid.

Frequently Asked Questions
Can I make extra repayments on a fixed rate investment loan?
Most lenders allow extra repayments of $10,000 to $30,000 per year on fixed rate investment loans without penalty. Repayments above that threshold trigger break costs, which are calculated based on the difference between your fixed rate and the lender's current funding cost for the remaining term.
What is a split loan structure?
A split loan divides your borrowing into two or more portions, typically one fixed and one variable. The variable portion accepts unlimited extra repayments without penalty, while the fixed portion provides rate certainty for a set term.
Are break costs on investment loans tax deductible?
No. The ATO treats break costs as capital in nature, which means they are not deductible as a borrowing expense. Interest on the investment loan itself remains deductible provided the borrowing is used to acquire or hold the rental property.
Can I switch from interest only to principal and interest during a fixed term?
Most lenders will allow you to switch from interest only to principal and interest repayments during a fixed term without a break cost, provided the change does not involve a discharge or refinance. However, any principal repayments above the annual cap will still incur break costs.
When should I consider fixing an investment loan?
Fixed rates provide certainty when rates are expected to rise or remain elevated, and suit investors who prefer predictable outgoings and do not plan to make extra repayments during the fixed term. Variable rates suit investors who want flexibility to reduce debt quickly or refinance to access equity.
