Rate Lock-ins and Break Costs for Investment Loans

Understanding Fixed Rate Break Costs on Investment Loans

Break costs are fees charged by lenders when you exit a fixed rate loan before the end of the fixed term. They compensate the lender for the difference between the rate you locked in and the rate they can now lend at, which means you pay more when rates have fallen and less, or nothing, when rates have risen.

Consider a buyer who locked in a three-year fixed rate at 5.8 per cent in late 2022 on a $450,000 investment loan for a unit near Adelaide's CBD. Two years into the fixed term, variable rates had dropped to 5.2 per cent, and the owner wanted to refinance to access equity for a second property. The break cost came to $11,400 because the lender had locked in funding at the higher rate and couldn't recover that margin once the borrower exited early. The calculation wasn't about punishing the borrower, it reflected the lender's actual cost of unwinding the fixed rate contract.

That difference between contracted and current wholesale funding rates drives the entire formula. Lenders don't publish the calculation in plain language, but the mechanics are consistent: they compare what they're earning from your fixed rate to what they could earn by redeploying that capital at today's wholesale rate, then multiply that gap by the remaining term. The longer the remaining fixed period and the larger the rate gap, the higher the break cost.

When Break Costs Apply and When They Don't

You trigger a break cost whenever you repay more than the allowable extra repayments during a fixed rate period. Most lenders allow up to $10,000 or $30,000 in additional repayments per year without penalty, but any amount above that threshold, whether from refinancing, selling the property, or making a lump sum payment, will attract the fee.

Break costs don't apply if you're switching from fixed to variable with the same lender and they waive the fee, though this is rare. They also don't apply once the fixed term expires, even if you're one day past the end date. Some lenders will waive break costs if you're refinancing a larger amount with them or consolidating multiple loans, but that depends on the individual lender's policy and the size of the new loan.

Refinancing within the same bank to access equity or adjust the loan structure usually still attracts break costs unless the lender has a specific policy exemption. Selling the property always triggers the fee if you're in a fixed term, because the loan is fully repaid. In our experience, borrowers often assume that selling for genuine reasons, such as financial hardship or relocation, will exempt them, but lenders apply the formula regardless of circumstance.

How to Structure Your Investment Loan to Reduce Break Cost Exposure

Splitting your investment loan between fixed and variable rates gives you flexibility to make extra repayments or refinance without unwinding the entire fixed portion. A common approach is to fix 50 to 70 per cent of the loan amount and leave the rest on a variable rate, so you can direct additional rental income or tax refunds to the variable portion and access equity or sell without paying break costs on the full balance.

For example, an Adelaide investor with a $500,000 loan might fix $300,000 for three years and leave $200,000 variable. If they sell the property 18 months into the fixed term when rates have dropped, the break cost applies only to the $300,000 fixed portion, reducing the total fee by around 40 per cent compared to fixing the entire loan. The variable portion also allows them to make unlimited extra repayments, which can bring the loan balance down faster if rental income exceeds expectations or if they receive a windfall.

Another option is to fix for a shorter term, such as one or two years instead of three or five. Shorter fixed terms mean lower break costs if you exit early, because the remaining term used in the calculation is smaller. However, shorter terms also mean you'll need to refix or revert to variable rates sooner, which exposes you to rate movements earlier. If you're planning to sell or refinance within two years, a one-year fixed term or a variable rate may be more suitable than locking in for three years.

What Happens When Your Fixed Rate Ends

When your fixed rate period expires, the loan automatically reverts to the lender's variable rate unless you proactively refix or refinance. The reversion rate is often higher than the variable rate offered to new borrowers, sometimes by 0.3 to 0.7 percentage points, which can increase your repayments by several hundred dollars per month on a typical investment loan amount.

Lenders send a notification 30 to 90 days before the fixed term ends, outlining your options to refix at current rates or switch to variable. If you do nothing, the loan moves to the reversion rate automatically. In our experience, landlords who don't act during that window often stay on the reversion rate for months without realising, because the repayment change can be gradual if rates haven't moved significantly.

If you're considering a loan health check before your fixed rate ends, it's worth comparing your current lender's refix rates against what's available elsewhere. Refinancing to a new lender at the end of a fixed term avoids break costs entirely and may secure a lower rate, though you'll need to factor in application fees, valuation costs, and discharge fees from your current lender. For many Adelaide investors, refinancing at the end of a fixed term is the most cost-effective time to reassess loan structure, especially if rental income has increased or the property has gained equity since the original loan was written.
