Fixed vs Variable Home Loans in Logan, QLD, What Lenders Actually Check
Your fixed rate is ending, or you're about to sign a loan and the broker has asked which way you want to go. Most people pick based on the rate in front of them. That's rarely the right way to make this decision, and it's why so many borrowers end up in the wrong structure six months later.
The choice between fixed and variable isn't just about today's rate. It's about how your income works, what you plan to do with the property, and which structure a lender will actually approve you on. Getting the structure wrong can cost you more than a bad rate will.
Cube Loans works with buyers and refinancers across Logan, QLD on exactly this decision, comparing structures across 60+ lenders to find what suits your situation. Our home loan team runs these comparisons every day.
Key takeaways
- Fixed rates lock your repayment but restrict extra payments and offset access.
- Variable loans give flexibility but expose you to rate movements both ways.
- A split loan locks part and keeps flexibility on the rest.
What's actually the difference between a fixed and variable home loan?
A fixed rate loan locks your interest rate for a set term, usually one to five years, so your repayment stays the same regardless of what the RBA does. A variable rate loan moves with the market, meaning your repayment can rise or fall as lenders adjust their rates in response to the cash rate, their funding costs, or competition.
That single distinction flows into almost every other feature of the loan. Variable loans typically allow unlimited extra repayments and come with an offset account. Fixed loans limit extra repayments and usually don't include offset access. Understanding that trade-off is the whole decision.
How do lenders assess a fixed vs variable application in Logan, QLD?
Lenders assess both loan types on the same serviceability basis, and that's the part most borrowers don't realise. Whether you pick fixed or variable, APRA requires lenders to test your ability to repay at your actual rate plus a 3.0% buffer. With the RBA cash rate at 4.35% as of 11 August 2026, that assessment rate sits at approximately 9% for most lenders, regardless of which structure you choose.
The structure choice doesn't change your serviceability number, but it does change two things that matter later: your ability to make extra repayments and reduce your interest bill, and your exposure if rates move significantly during your fixed term. A borrower who fixes for three years and then needs to sell or refinance early can face a break cost that runs to thousands.

We see borrowers assume that choosing a fixed rate means they've locked in safety. What they've actually locked in is a set repayment. Whether that's safe depends entirely on what happens to their income, their plans and the market over the fixed term, and most people don't think past the first year.

What do you need to qualify for each structure?
The eligibility criteria are the same for fixed and variable loans. Lenders assess your income, your existing debts, your credit history and your deposit. The structure you choose sits on top of that assessment, not underneath it.
What lenders look at across both structures:
- › Deposit and LVR: most lenders require at least 5% deposit, though a 20% deposit avoids lenders mortgage insurance on either structure.
- › Serviceability at the buffer rate: your income minus debts and living costs must clear approximately 9%, on both fixed and variable.
- › Credit history: assessed the same way regardless of structure; defaults and enquiries affect both equally.
- › Employment type: PAYG borrowers are straightforward on either; self-employed borrowers need two years of returns regardless of structure.
- › Loan purpose: owner-occupier and investor loans have different pricing on both structures; investors sometimes face a rate premium on either.
What does each structure actually cost, and what does it give you?
The options have genuinely different cost and flexibility profiles. Rather than comparing rate numbers, which change constantly, the comparison worth making is on features, because those are what the structure decision locks in.
The options worth weighing:
- › Fixed rate: set repayment for the term · limited extra repayments · usually no offset account · break costs apply if you exit early
- › Variable rate: repayment moves with the cash rate · unlimited extra repayments · offset account available · no break cost to exit or refinance
- › Split loan: fixed portion locked · variable portion keeps offset and flexibility · break cost applies only to the fixed portion · two rates to manage
For a Logan buyer purchasing in Woodridge, Marsden or Loganholme, the split structure is often where people land once they understand what they're giving up on a pure fixed loan.

How long does it take, and when does the decision actually get made?
The structure decision gets made at application, and changing it after settlement is not straightforward. Switching from fixed to variable mid-term triggers break costs. Switching from variable to fixed is cleaner but still involves a new application or a product switch with your existing lender.
The practical timeframes worth knowing:
- › Fixed rate expiry: your lender notifies you roughly 30 days before the fixed term ends; you have a short window to choose the next structure before reverting to a variable rate.
- › Break cost calculation: calculated by the lender at the time of the request; it can shift significantly week to week depending on wholesale interest rates.
- › Refinancing at expiry: switching lenders at the end of a fixed term typically takes three to six weeks and involves a fresh application and a new valuation.
- › Rate lock at application: some lenders offer a rate lock for a fee, holding the offered fixed rate for 60 to 90 days while your application processes.
When does fixing your rate not make sense in Logan, QLD?
Fixing your rate is the wrong move when you're likely to need flexibility within the fixed term. If there's a reasonable chance you'll sell, refinance, receive a significant lump sum, or need to restructure the loan inside the term, the break cost can easily outweigh any rate saving.
It also works against you when your income is variable and you'd otherwise use an offset account to reduce interest day by day. A nurse banking shift penalty payments into an offset account between pay cycles is systematically reducing their interest bill on a variable loan. That mechanism disappears on a fixed rate, and the rate difference rarely compensates for it.
For most Logan buyers who are early in their property journey, the flexibility of a variable loan, or a split where the majority stays variable, is the structure that costs them less over the first three to five years, even when the fixed rate looks lower on paper.
When someone's leaning toward fixing, I want to know two things first: whether they're planning to make extra repayments, and whether there's any chance they'll need to sell or refinance within the fixed term. If the answer to either is yes, I'd usually push them toward a split or a variable rather than a pure fixed rate, because the break cost risk is real and the rate saving rarely covers it.

How to choose your rate structure in Logan, QLD, step by step
Step 1: Talk to us
We start by understanding your income shape, your plans for the property, and whether flexibility matters more than certainty for your situation right now.
Step 2: Map your income against both structures
We work out what your offset account would realistically hold each month, and whether the interest saving on a variable loan outweighs the rate difference the fixed term offers.
Step 3: Compare lenders on both sides of the decision
Fixed and variable pricing varies significantly across the 60+ lenders on our panel. We identify which lenders offer competitive fixed terms with the least restrictive break cost clauses, and which variable products include genuine offset features.
Step 4: Apply and lock in the structure before settlement
Once the structure is chosen, we manage the application and, where relevant, arrange a rate lock to protect the offered fixed rate while the loan processes to settlement.
What goes wrong when people choose a rate structure in Logan?
Where borrowers lose ground:
- › Fixing before a likely sale: break costs on fixed loans are calculated on wholesale rate movements, not the time remaining, and can be substantial even early in the term. Borrowers who sell within the first year of a fixed term often pay more in break costs than they saved on the lower rate.
- › Ignoring the offset account value: a variable loan with a genuine offset account is more cost-effective than a fixed rate for borrowers who consistently hold savings. The offset benefit compounds daily, and most borrowers underestimate how much interest it saves over three years.
- › Reverting to a high variable rate at expiry: when a fixed term ends, the loan rolls to the lender's standard variable rate, which is typically not competitive. Borrowers who don't act in the notification window end up paying significantly more than they would on a negotiated or refinanced rate.
- › Choosing structure based on rate alone: a fixed rate that looks 0.4% lower than the best variable can still be the wrong structure if the borrower plans to make large extra repayments. The interest saving from those repayments on a variable loan often exceeds the rate differential.
Frequently Asked Questions
Is it better to fix or stay variable in Logan, QLD right now?
That depends on your plans for the property and whether you'll use an offset account. Borrowers expecting to make extra repayments or sell within three years are usually better served by a variable or split structure, regardless of which rate looks lower today.
Should fixed vs variable home loans be decided before or after pre-approval?
The structure decision can wait until you've found the property, since serviceability is assessed the same way on both. Locking the structure too early means you may miss rate movements between pre-approval and settlement.
Is a split loan better than choosing one structure for Logan home loans?
A split loan suits borrowers who want certainty on part of the loan but don't want to give up offset flexibility entirely. It's a reasonable middle ground, though it involves managing two rate environments rather than one.
What happens to my fixed rate loan when the RBA changes the cash rate?
Nothing, while the fixed term is active. Your repayment stays the same until expiry, at which point the loan reverts to a variable rate that will reflect current market conditions.
Can I make extra repayments on a fixed rate loan?
Most lenders allow extra repayments on fixed loans up to a cap, commonly around $10,000 per year. Exceeding that cap can trigger a break cost, so it's worth confirming the limit before committing to the structure.
Is a mortgage broker or my current bank better for this decision?
A mortgage broker, every time. Your bank will show you their fixed and variable products. A broker compares fixed and variable options across 60+ lenders, including the break cost clauses and offset conditions, and recommends the structure and lender that suit your situation.
Your Next Steps
The right structure for your home loan depends on your income, your plans and which lenders your broker has access to. A fixed rate that looks attractive today can be expensive to exit, and a variable loan that looks uncertain now can save significantly if you're using an offset account well. Getting that analysis right before you sign is what makes the difference.
The right structure for your home loan depends on the full picture of your situation, and that's a conversation worth having. Talk to the Cube Loans team or call 1800 774 756, and we'll compare your options across 60+ lenders.
