Proven Tips to Lock Fixed Rate Terms for Investment Loans

Fixed rate terms on investment loans give you certainty over your repayments for a set period, typically between one and five years.

For Mandurah investors watching recent Budget changes to negative gearing and capital gains tax, knowing exactly what your loan will cost each month removes one major variable from your planning. The difference between a one-year and five-year fixed term isn't just about duration. It's about how closely your strategy aligns with your portfolio goals, your view on rate movements, and what's happening in the local rental market.

Why Fixed Rate Duration Matters for Cashflow Planning

The term you choose determines how long your repayments remain unchanged. A longer fixed term locks in protection against rate rises for an extended period, while a shorter term gives you more flexibility to refinance or restructure as market conditions shift.

Consider an investor who secures a three-year fixed rate on a Mandurah property near the Peel-Harvey Estuary precinct. Rental demand in that area remains strong due to proximity to the foreshore and established schools, so they're confident the property will stay tenanted. Fixing for three years means their monthly outgoings stay predictable through that period, making it easier to plan for a second purchase or to absorb any vacancy without immediate pressure. When the fixed term ends, they can reassess whether to refix, switch to variable, or refinance the investment loan entirely based on what rates and their circumstances look like at that point.

Shorter fixed terms, such as one or two years, suit investors who expect rates to fall or who want the option to access offset accounts and redraw facilities sooner. Longer terms suit those prioritising stability over flexibility, especially if they're managing multiple properties or relying on interest only repayment structures to maximise cashflow.

How Fixed Rate Investment Loans Interact with New Tax Settings

From 1 July 2027, residential investment properties purchased after Budget night will no longer allow losses to be offset against wage income. Losses can still be carried forward and offset against future rental income or capital gains, but the immediate tax benefit disappears.

This doesn't eliminate the value of fixed rates. It shifts the focus. Without the ability to reduce your taxable income through negative gearing, your cashflow becomes even more important. A fixed rate term that aligns with your expected hold period can stabilise your position during the transition, particularly if you're holding a property through a period of lower rental yield while waiting for capital growth.

Mandurah's median rental yield sits slightly higher than many Perth metro areas, partly due to more affordable entry points and steady demand from retirees and sea-changers. An investor purchasing an established property before the new rules take effect can still claim the full negative gearing deduction and benefit from the existing 50% CGT discount. Locking a fixed rate now, before any further rate movements, can protect that position while you build equity and prepare for the next phase of your strategy.

Choosing Between One, Three, and Five-Year Fixed Terms

Each term length serves a different purpose. One-year fixed terms work when you expect rates to drop within the next 12 months or when you're planning to sell or refinance in the near term. They offer some short-term protection without committing you to a long period where you might miss out on lower variable rates.

Three-year terms are the most commonly chosen. They provide a reasonable balance between rate protection and flexibility, and they align well with investors who are planning to hold a property through a full rental cycle or who want to lock in current pricing without overcommitting.

Five-year terms suit investors with a longer outlook who want maximum certainty. The trade-off is reduced flexibility. If you need to break the loan early due to sale, refinance, or a significant life change, break costs can be substantial. These costs are calculated based on the difference between your fixed rate and the lender's current wholesale funding cost for the remaining term. The longer the remaining period, the higher the potential cost.

In our experience, investors who fix for five years are typically managing larger portfolios where one property's loan structure is part of a broader plan, or they're holding through a development phase and don't need access to the equity in that particular asset.

Splitting Fixed and Variable Rates Across the Same Loan

Many lenders allow you to split your loan between fixed and variable portions. This gives you some rate protection on part of the balance while keeping access to offset accounts and flexible repayment options on the rest.

As an example, an investor with a loan across two Mandurah properties might fix 60% of the total borrowing on a three-year term to stabilise the majority of repayments, while leaving 40% on a variable rate with an offset account attached. Rental income can sit in the offset, reducing interest on the variable portion, while the fixed portion provides a floor on monthly costs. If rates rise, the fixed portion absorbs most of the impact. If rates fall, the variable portion benefits immediately, and the investor can choose not to refix when the term ends.

This structure also reduces break costs if you need to pay down the loan early, because only the fixed portion is subject to those fees. The variable portion can be repaid in full at any time without penalty. It's a particularly useful approach for investors who are building wealth through property but want to retain some liquidity and flexibility as their portfolio grows.

Fixed Rate Terms and Portfolio Timing

The term you choose should reflect your broader investment timeline. If you're planning to use equity from one property to fund the deposit on another, you need to know when that equity will be accessible without triggering break costs.

Mandurah's property market has seen consistent interest from both local upgraders and interstate buyers seeking affordable coastal access. For investors, this creates opportunities to build equity relatively quickly if you're buying in precincts with strong demand, such as around Halls Head or the Mandurah Ocean Marina. However, accessing that equity before a fixed term ends can be expensive if you're locked into a rate that's higher than current market pricing.

Planning your fixed term to end around the time you expect to need access to equity allows you to refinance or release equity without penalty. This is particularly relevant for investors looking to expand their property portfolio in a structured way, where each purchase is timed around the equity position of the previous one.

What Happens When Your Fixed Rate Term Ends

When the fixed period expires, your loan will automatically revert to the lender's standard variable rate unless you take action. That reversion rate is almost always higher than the discounted variable rates available to new customers or those actively refinancing.

This is the point where many investors lose ground. They assume the transition will happen smoothly, but without reviewing their loan at least 90 days before the term ends, they can end up paying significantly more than necessary. In some cases, the reversion rate can be a full percentage point higher than what you could secure by refinancing or negotiating a new fixed term.

For Mandurah investors, this is also an opportunity to reassess your investment loan options based on how the property has performed. If rental income has increased and the loan-to-value ratio has improved, you may qualify for higher discounts or access to product features that weren't available when you first borrowed. Alternatively, if your strategy has shifted and you're planning to sell within the next 12 months, moving to a variable rate with no break costs might make more sense than locking in again.
