Everything you need to know about Fixed Rate Investment Loans

Fixed Rate Investment Loans: What They Actually Lock In

A fixed rate investment loan holds your interest rate steady for an agreed period, which is usually between one and five years. During that time, your repayments stay the same regardless of what happens to the official cash rate or what variable rates do.

Consider a buyer who secures a unit in Smithfield with a three-year fixed rate at the start of their investment journey. If variable rates climb during those three years, their repayments don't change. If rates fall, they're still locked into the original figure until the fixed period ends. That predictability makes budgeting simpler when you're managing rental income against loan repayments, but it also means you're committed to that rate whether the market moves in your favour or not.

The fixed period doesn't change the total loan term. If you take out a 30-year loan with a three-year fixed rate, you still have 30 years to repay the loan. Once the fixed period ends, the loan typically reverts to the lender's variable rate unless you refinance or lock in another fixed term.

How Long Should You Fix an Investment Loan?

The right fixed term depends on how long you expect rates to stay above where they are now and whether you might need to access equity or sell within that period.

Shorter fixed terms of one or two years suit investors who expect rates to fall soon or who want the option to refinance without penalty. Longer terms of four or five years make sense if you're confident rates will rise and you want certainty over a longer stretch. Three-year fixed terms sit in the middle and tend to be the most common choice for investors who want some protection without locking in for too long.

In Smithfield, where many investors are buying affordable units or townhouses as first or second properties in their portfolio, a two or three-year fixed term often aligns with plans to refinance once equity builds or when they're ready to expand their property portfolio. That time frame gives enough stability to manage early cashflow without trapping you if circumstances change.

Interest Only Repayments on Fixed Rate Investment Loans

Most lenders let you choose interest only repayments during the fixed period. This means you only pay the interest charged each month and don't reduce the loan balance. For investors, that keeps repayments lower and can improve cashflow, especially if rental income doesn't cover the full principal and interest repayment.

Interest only periods typically run for one to five years, and they can align with your fixed rate term or differ from it. If you fix for three years and take interest only for five, the first three years are fixed interest only, and the remaining two years are variable interest only before the loan converts to principal and interest.

Smithfield sits close to major employment hubs in Adelaide's northern suburbs, including Munno Para and Elizabeth, which keeps rental demand steady. An investor who buys a unit near the Peachey Road precinct might choose interest only repayments to keep costs manageable while tenants cover most of the loan. When the interest only period ends, repayments increase because you start paying down the principal as well as the interest.

What Happens When Your Fixed Rate Ends

When the fixed period expires, your loan automatically moves to the lender's variable rate unless you take action beforehand. Variable rates are typically higher than the advertised fixed rates you see when shopping around, so your repayments usually increase.

Most lenders contact you a few months before the fixed term ends to discuss your options. You can lock in another fixed rate, switch to variable, or refinance to a different lender if you find something more suitable. If you do nothing, the loan continues on the variable rate that applies at that time.

In a scenario where an investor fixed a loan three years ago at a lower rate and variable rates have since increased, the jump in repayments at the end of the fixed term can be significant. That's why it's worth reviewing your options at least three months before the fixed period ends, rather than waiting for the automatic rollover.

Early Exit Fees and Break Costs

If you pay off your fixed rate loan early, switch to another product, or refinance before the fixed period ends, most lenders charge a break cost. This fee compensates the lender for the interest they expected to receive over the remaining fixed term.

Break costs are calculated based on the difference between your fixed rate and the current market rate, plus the time left on your fixed period. If rates have fallen since you fixed, the break cost can run into thousands of dollars. If rates have risen, the cost might be minimal or even zero.

Some lenders allow partial repayments during the fixed period without penalty, often up to a certain amount each year. That can be useful if you receive a lump sum or want to reduce the loan balance gradually without triggering a full break cost. Check the loan terms before committing to a fixed rate if you think you might need that flexibility.

Fixed vs Variable for Investment Property

Fixed rates give you certainty, but they usually come with fewer features. Most fixed rate investment loans don't let you access an offset account or redraw facility, and they limit how much extra you can repay each year. Variable loans offer more flexibility, including offset accounts that can reduce the interest you pay if you park rental income or savings there.

Many investors split their loan between fixed and variable. That way, part of the loan is protected from rate rises, and the rest stays flexible for extra repayments or redraw. A 50/50 split is common, but you can adjust the ratio to suit your priorities. If you value certainty over flexibility, you might fix 70% and leave 30% variable. If you want more control, reverse that split.

Smithfield's proximity to transport and shopping centres, including Munno Para Shopping City and the Northern Expressway, makes it a practical choice for tenants working across Adelaide's northern suburbs. Investors buying in the area often choose investment loans that balance fixed and variable features so they can respond to changes in the rental market without losing rate protection entirely.

Fixed Rates and the 2027 Tax Changes

The Federal Budget introduced changes to negative gearing and capital gains tax that take effect from 1 July 2027. If you bought an established investment property after 12 May 2026, rental losses can only be offset against other property income, not against your wages or salary. That means the tax benefit of negative gearing is reduced for new purchases of established properties.

New builds are exempt from the negative gearing changes, and investors who buy new construction in Smithfield can still claim rental losses against their full income. The capital gains tax discount also remains at 50% for new builds, while established properties purchased after Budget night will move to a different arrangement.

If you're buying an established property and your fixed rate ends after July 2027, the change in tax treatment might affect how much rental loss you can claim. That's worth factoring into your cashflow projections when choosing a fixed term. A longer fixed period might lock in lower repayments now, but it also extends the time before you can refinance or adjust your strategy in response to the new tax rules.

Fixing your rate or staying variable comes down to how much certainty you want and whether the loan features you're giving up matter for your situation. Call one of our team or book an appointment at a time that works for you.
