Variable rates have delivered periods of savings, but uncertainty erodes strategy. Switching to a fixed rate through refinancing gives you cost certainty, protects your cashflow against future rate rises, and creates a stable foundation for the next phase of your wealth plan.
Why refinance from variable to fixed rather than convert your existing loan
Most lenders allow you to convert from variable to fixed within your current loan, but refinancing to a new lender often delivers a lower fixed rate and unlocks features your current lender won't offer. Converting might feel convenient, but it rarely positions you for long-term savings. In our experience, refinancing opens the door to offset accounts on the fixed portion, partial splits between fixed and variable, and the ability to release equity at the same time if you're preparing for your next acquisition.
Consider a Sunshine Coast investor holding a Maroochydore unit on a variable rate at 6.45%. Converting with their existing lender offered a three-year fixed rate at 6.15%, but refinancing to a different lender secured 5.85% with a full offset account attached to the fixed component. Over three years, the rate difference alone would save thousands, and the offset feature preserved liquidity for their next deposit.
What it costs to refinance and how to calculate whether the move is worth it
Refinancing involves discharge fees from your current lender, application fees with the new lender, valuation costs, and potential legal fees. Discharge fees typically sit between $300 and $500, valuation costs range from $200 to $400, and some lenders charge application fees up to $600, though many waive this during competitive periods. The calculation that matters is whether the interest rate reduction over your intended fixed period exceeds these upfront costs.
A Sunshine Coast homeowner refinancing a loan of $600,000 from a variable rate of 6.50% to a fixed rate of 5.90% would save approximately $3,600 per year in interest. If refinancing costs total $1,200, the breakeven point arrives within four months. Beyond that, every dollar saved compounds your position. A loan health check helps you model these numbers against your current loan structure and long-term plans.
Fixed rate periods and what length suits your strategy
Fixed rate terms range from one to five years, and the right choice depends on where you sit in your wealth cycle. Shorter fixed terms suit investors planning another purchase within two years because break costs on a one or two-year fixed loan remain manageable if you need to refinance early to access equity. Longer fixed terms suit owner-occupiers prioritising certainty over flexibility, particularly if household income fluctuates or you're approaching retirement.

Sunshine Coast property owners with plans to expand their portfolio within three years often lock in a two-year fixed rate while keeping a portion on variable. This split structure delivers certainty on repayments while preserving the ability to make extra payments on the variable portion without penalty. If rates fall during the fixed period, the variable portion captures that benefit immediately.
How refinancing to fixed affects your ability to access equity later
Fixed rate loans carry break costs if you refinance or increase your loan amount before the fixed term ends. These costs reflect the lender's loss when you exit a fixed contract early, calculated on the difference between your fixed rate and the current wholesale rate, multiplied by your remaining loan balance and term. Break costs can reach tens of thousands on large loans with several years remaining, which makes timing critical if you intend to access equity for your next investment.
Refinancing to fixed now while simultaneously releasing equity for a future deposit avoids this issue entirely. You lock in your rate, draw the funds you need, and structure the loan so no further refinancing is required until the fixed term ends. This approach suits investors who know their next move is 12 to 18 months away and want certainty now without constraining future flexibility.
The split rate structure that preserves flexibility while locking in certainty
Splitting your loan between fixed and variable portions allows you to lock in a portion of your debt at a lower rate while maintaining offset access and repayment flexibility on the variable side. A common split is 70% fixed and 30% variable, though the right ratio depends on your cashflow needs and growth plans. The variable portion absorbs extra repayments without penalty, and any offset balance reduces interest on that portion daily.
A Sunshine Coast couple refinancing their Buderim home loan chose a 60% fixed, 40% variable split. The fixed portion at 5.80% delivered $18,000 in savings over three years compared to their previous variable rate, while the variable portion allowed them to park rental income from their investment property in an offset account and reduce interest in real time. When their fixed rate expires, they'll reassess whether to refix, move fully variable, or adjust the split based on market conditions at that time.
What happens when your fixed rate period ends
When your fixed term expires, your loan reverts to the lender's standard variable rate unless you take action. Standard variable rates sit higher than advertised variable rates, sometimes by 0.50% or more, which means inaction costs you. The window to refinance or negotiate opens around 90 days before expiry, and lenders often contact you with retention offers during this period. These offers may look attractive, but they rarely match what a new lender will provide to win your business.
If you're coming off a fixed rate, refinancing to a new lender or renegotiating with your current lender should happen before expiry, not after. Once you revert to the standard variable rate, you've already started paying more, and the urgency to move you to a lower rate disappears from the lender's perspective. Reviewing your loan structure 120 days before expiry ensures you're positioned to lock in the next phase of your plan without paying more than necessary in the interim.
When switching to fixed makes sense and when it doesn't
Switching from variable to fixed makes sense when you value certainty over flexibility, expect rates to rise or remain elevated, or need predictable repayments to support borrowing capacity for your next investment. It doesn't make sense if you plan to sell within 12 months, need regular access to equity, or believe rates will fall significantly during the period you'd be locked in.
Refinancing decisions should align with your broader wealth strategy, not react to short-term rate movements. If your next property purchase is two years away and you want to protect cashflow now, fixing makes sense. If you're holding cash in offset and rates are falling, staying variable might preserve more flexibility. The decision depends on your portfolio, your timeline, and your risk tolerance, which is where advice grounded in your full financial picture becomes essential.

Frequently Asked Questions
Why should I refinance to fixed instead of converting with my current lender?
Refinancing to a new lender often delivers a lower fixed rate and unlocks features like offset accounts or split loan structures that your current lender won't offer. Converting might be convenient, but it rarely positions you for long-term savings or flexibility.
How much does it cost to refinance from variable to fixed?
Refinancing costs typically include discharge fees ($300 to $500), valuation costs ($200 to $400), and potential application fees up to $600. The move is worth it if your interest savings over the fixed period exceed these upfront costs, often within a few months.
What fixed rate term should I choose?
Shorter fixed terms (one to two years) suit investors planning another purchase soon because break costs remain manageable. Longer terms (three to five years) suit owner-occupiers prioritising certainty and predictable repayments over flexibility.
Can I still access equity after refinancing to a fixed rate?
Yes, but increasing your loan during a fixed term triggers break costs. The solution is to refinance to fixed and access equity at the same time, structuring the loan so no further refinancing is required until the fixed term ends.
What happens when my fixed rate period ends?
Your loan reverts to the lender's standard variable rate, which is often higher than advertised rates. You should review your options 90 to 120 days before expiry to refinance or negotiate a lower rate before the fixed term ends.
