Understanding the costs of fixed rate investment loans

A fixed rate investment loan insulates your borrowing cost from rate movements for the term you select.

That certainty comes at a price. Lenders typically charge establishment fees, ongoing account fees, and break costs if you repay or refinance before the fixed term ends. Each of these costs affects your net rental yield and the overall return on the property, particularly where vacancy periods or capital works reduce cash flow in the early years.

The decision to fix part or all of your borrowing depends on your appetite for interest rate risk, your cash flow buffer, and how long you intend to hold the property without restructuring. If you understand the fee structure upfront, you can model the true cost of certainty and decide whether it suits your investment strategy.

How establishment and application fees are structured

Most lenders charge an upfront application or establishment fee when you take out a fixed rate investment loan. The fee covers credit assessment, valuation, documentation, and settlement. It typically ranges from $300 to $900, though some lenders waive it during promotional periods or for high-value borrowers.

Consider a buyer who borrows $600,000 to acquire a rental property in Mulgrave. The lender charges a $600 establishment fee and orders a valuation at $350. Both are payable at settlement, so the borrower needs to include them in the settlement statement and ensure sufficient funds are held in their solicitor's trust account. The establishment fee is usually a one-off cost, not added to the loan balance, though some lenders offer the option to capitalise it. Capitalising the fee increases your loan amount and reduces your equity from day one, which can push you into a higher LVR band and trigger Lenders Mortgage Insurance if you are near the 80 per cent threshold.

Valuation fees are separate from the establishment fee and are paid directly to the valuer or reimbursed to the lender. Where the valuation is ordered by the lender as part of the credit assessment, you do not receive a copy unless you request it and the lender agrees. Some brokers arrange for an independent valuation before lodging the application, particularly where the purchase price is at or above the suburb median and the buyer wants certainty before proceeding.

Ongoing account and service fees

Fixed rate investment loans typically incur an annual or monthly account keeping fee, separate from interest. The fee is charged regardless of whether the loan is interest-only or principal and interest, and it applies throughout the fixed term.

Annual fees range from $200 to $395 depending on the lender and the product features. Some lenders charge the fee monthly, others annually in advance. The fee is generally not tax-deductible against wage income under current ATO interpretation, but it forms part of the holding cost of the property and can be claimed as a deduction against rental income provided the property is genuinely available for rent.

Where a loan includes an offset account or redraw facility during the fixed term, some lenders charge an additional monthly fee for that feature. Offset accounts are uncommon on fixed rate investment loans because most lenders either do not offer them on fixed products or charge a rate premium and a monthly fee. If your strategy involves parking surplus cash to reduce interest, a variable rate product with a full offset is usually more cost-effective than a fixed loan with a partial offset and a monthly service fee.

Break costs and how they are calculated

Break costs apply when you repay, refinance, or make a lump sum payment above the allowable threshold during a fixed rate term. The cost compensates the lender for the difference between the fixed rate you agreed to pay and the rate at which the lender can now reinvest the funds.

The formula used by most lenders compares the present value of the contracted interest payments remaining over the fixed term with the present value of the same payments at the current wholesale funding rate for the same remaining term. If wholesale rates have fallen since you fixed, the lender faces a funding loss and charges you the difference. If rates have risen, there is usually no break cost, though some lenders still charge an administrative fee.

Consider a scenario where a Mulgrave investor fixed a $500,000 loan at 5.8 per cent for five years. Two years into the term, they decide to refinance to access equity for a second property. The lender's current three-year fixed rate, which reflects the remaining term, is 4.6 per cent. The difference is 1.2 percentage points, and the remaining balance is approximately $490,000. The break cost calculation discounts the 1.2 percentage point margin over three years back to present value, which in this case produces a break cost of around $16,800. The actual figure depends on the lender's funding curve and the precise number of days remaining, but it can easily exceed $15,000 on a mid-sized loan where rates have moved materially.

Some lenders cap annual lump sum repayments at $10,000 or $30,000 during the fixed term without penalty. If you stay within that threshold, no break cost applies. The cap is per calendar year or per financial year depending on the lender's terms, so it may reset annually or on the anniversary of settlement.

Switching fees and early exit charges

Some lenders charge a fixed rate lock-in fee at application if you want to secure a rate before settlement. The fee is typically $500 to $750 and is non-refundable if you do not proceed. It guarantees the rate for a set period, usually 90 days, which can be valuable in a rising rate environment but represents a sunk cost if the purchase falls through or you change lenders.

If you choose to switch from a fixed rate to a variable rate during the fixed term, most lenders treat this as a break and apply the full break cost calculation described above, even if you remain with the same lender. There is no discount for staying. The exception is where the lender offers a genuine product switch without break costs as a retention feature, which is rare and usually only available where rates have not moved in the lender's favour.

During the fixed term, you are generally locked into the repayment structure you selected at settlement. Switching from interest-only to principal and interest, or vice versa, may require lender consent and can trigger a re-assessment of serviceability, particularly if rental income has declined or vacancy periods have affected cash flow. Some lenders treat a structural change as a variation and charge a fee of $300 to $500, even where no break cost applies.

Legal and discharge fees at the end of the term

When the fixed term expires, the loan typically reverts to the lender's standard variable rate for investment loans unless you refinance or negotiate a new fixed term. If you choose to refinance to another lender at the end of the fixed term, you will incur discharge fees from the outgoing lender and settlement fees with the new lender.

Discharge fees cover the administrative cost of releasing the mortgage and providing a discharge authority to your solicitor. They range from $300 to $500 depending on the lender. Government registration fees to remove the mortgage from the title vary by state, and in Victoria the fee is currently $129.90 per mortgage.

If you hold multiple investment properties with mortgages registered against each title, you pay a separate discharge fee and registration fee for each security property, even if all loans are with the same lender. In some cases, a lender will cross-collateralise loans, meaning a single mortgage secures multiple loans. Discharging a cross-collateralised mortgage can be more complex and may require the lender to consent to a partial discharge if you are selling one property but retaining others.

Settlement fees for the new lender typically mirror the costs you paid at the original settlement, including application fees, valuation, and legal costs. Lenders occasionally offer refinance packages that waive some of these fees, but you should confirm what is covered and what remains payable before committing.

Tax treatment of loan fees and costs

Establishment fees, ongoing account fees, valuation fees, and break costs all have different tax treatments under current ATO guidance. Establishment fees and legal costs incurred to set up an investment loan are not immediately deductible. Instead, they are either added to the cost base of the property for CGT purposes or deducted in equal portions over five years or the term of the loan, whichever is shorter.

Ongoing account keeping fees are fully deductible in the year they are incurred, provided the loan is used to acquire or hold an income-producing property and the property is rented or genuinely available for rent. If the property is vacant and not advertised for rent, the deduction may be disallowed for that period.

Break costs incurred when refinancing or repaying an investment loan early are generally deductible over the remainder of the original fixed term, not in the year the cost is paid. If you incur a $16,000 break cost with three years remaining on the fixed term, you would claim approximately $5,333 per year for the next three years, provided the new loan or remaining borrowing continues to be used for investment purposes. If you repay the loan in full and do not refinance, the deduction is spread over the remaining term even though you no longer hold the loan.

LMI premiums paid on an investment loan are treated in the same way as establishment fees and must be deducted over five years or the loan term. The premium is calculated based on the loan amount and LVR, and it can exceed $20,000 on a high-LVR loan. Some investors elect to pay the LMI premium upfront rather than capitalise it, to reduce the loan balance and preserve equity, but the tax treatment is the same regardless of how the premium is funded.
