Fixed Rate Expiring On An Investment Loan on the Gold Coast, QLD, What to Do Next

When a fixed rate expires on an investment loan, most borrowers do one of two things: they let the loan roll to the variable rate automatically, or they hurriedly call their existing lender and fix again without comparing anything. Both approaches tend to leave money on the table, and on an investment loan the difference compounds year after year across your whole position.

If your fixed term is ending in the next three to six months, you are in the window where the most useful work can be done. The Gold Coast investment market has run hard, with unit medians across mid-market suburbs sitting well under the $1,000,000 mark and house medians in most areas above it, which means the equity position in most portfolios has improved materially since the last fix was set. That equity is now part of the conversation.

Our team works with investors across Gold Coast, QLD on exactly this decision, comparing across 70+ lenders to find the right structure once a fixed term ends. The investment loan side of things is where lender policy differs most, and where comparing properly pays off.

What actually happens when a fixed investment loan expires on the Gold Coast, QLD?

When your fixed rate ends, the loan moves to the lender's standard variable rate for investment loans automatically, unless you act. That revert rate is almost never the most competitive rate the lender offers, and it is not what you would be offered as a new customer. It is the rate the lender sets for borrowers who do not shop around, and it is usually materially higher than what a new application would attract.

The three to six months before expiry is the window that matters. Within that window you can refinance to another lender, re-fix with your existing lender, or move to a variable product, and the lender still has reason to negotiate. Once the loan has already rolled, you lose that leverage. You are no longer a decision the lender is trying to win. You are an existing account on the existing rate.

How do lenders reassess an investment loan at rollover?

A rollover is not a passive event for the lender. When you ask to re-fix or refinance, the lender runs a fresh serviceability assessment on your whole position. That means your current income, your current debts, and your current property values, not the ones from when you first borrowed.

The APRA serviceability buffer sits at 3 percentage points above the actual rate you are applying for. So if you are looking at a variable or fixed rate in the mid-to-high sixes, the lender is testing repayments at close to 9% or above. That buffer is the same for an existing borrower refinancing as it is for someone buying for the first time, and it is the single biggest reason an investor can find their borrowing capacity has tightened even though their income has not changed.

Rental income is typically shaded to around 80% of gross when it is assessed, and property holding costs are added on top. If your portfolio has grown, the gross income looks higher but the costs do too. Where you sit in the APRA debt-to-income framework also matters: lenders can write no more than 20% of new lending at a debt-to-income ratio above six times gross income, and that quota bites hardest on investor books. Some lenders exhaust their investor quota before others, which is why the same borrower gets different answers from different lenders in the same week.

What does a fixed rate expiry cost on the Gold Coast, QLD?

The immediate cost is the gap between your fixed rate and the revert variable rate. On an investment loan that gap can be 0.30% to 0.60% or wider, and on a $600,000 loan a 0.40% difference is roughly $2,400 a year in extra interest. That is before any refinancing costs are factored in on the other side.

The costs of refinancing are real and worth counting. Discharge fees, settlement fees, and government mortgage registration charges apply in Queensland. An application with a new lender typically attracts its own establishment or valuation fee. These are one-off, but they matter when you are deciding whether moving lenders is worth it on a loan with a short remaining term.

The options worth comparing:

• › Re-fix with existing lender: no refinancing costs · rate is what the lender offers, not what the market offers · serviceability reassessed · fastest to execute
• › Refinance to a new lender: access to the full market · one-off switching costs · full serviceability test · equity may support a better LVR
• › Roll to variable and review: no immediate action · revert rate applies from day one · offset and redraw flexibility opens up · no lock-in on timing

How long does it take to refinance an investment loan?

Refinancing an investment loan typically takes four to six weeks from application to settlement. Valuations on Gold Coast investment properties can come in under the contract price where the building has a high density of similar stock, so valuation timing is one variable worth allowing for, particularly in Surfers Paradise or Broadbeach where high-rise supply is concentrated.

A pre-approval or conditional approval adds a week or two to the front end but removes uncertainty. Starting the process three months before your fixed rate expires gives enough time to compare, apply, receive a valuation, and settle a refinance without any pressure. Starting at four weeks is possible but tight, and a valuation delay or a request for additional documents can push settlement past the expiry date.

When does refinancing an expiring investment loan not make sense?

If you plan to sell the property within the next twelve to eighteen months, the savings from a lower rate may not cover the one-off switching costs. A break-even calculation on a $650,000 investment loan refinanced to save 0.30% takes roughly eighteen months to recover a $2,500 switching cost. If the timeline is shorter, rolling to the variable rate and reviewing later costs less.

Where the loan is cross-collateralised with other properties, refinancing one security requires the lender's consent on the others. That turns what looks like a single loan decision into a portfolio restructure, and the timing may not suit if other loans are mid-term or if the combined LVR doesn't support releasing one lender's security cleanly. Re-fixing with the existing lender is the simpler path in that scenario, even if the rate is not the sharpest available.

For most investors with a standalone loan and a remaining term of five or more years, refinancing is usually worth running the numbers. The savings compound, and the process of shopping the market often reveals a lender whose policy on rental income or DTI assessment is more favourable than the current one.

How to refinance an expiring investment loan on the Gold Coast, QLD, step by step

Step 1: Talk to us

We start by reviewing your current loan, your rental income, and your whole property position before the fixed rate expires, so we know what the market will offer before you have to decide anything.

Step 2: Assess your position and the market

We run a serviceability check across the lenders most likely to suit your situation, including how they treat rental income shading, your DTI ratio, and any other investment loans already on your books.

Step 3: Apply and support the valuation

Once you choose a direction, we manage the application, coordinate the lender's valuation, and handle any requests for additional documents so the process stays on track before your expiry date.

Step 4: Settle and structure for what's next

We confirm settlement timing with both lenders and make sure the loan structure, including interest-only terms and offset access where relevant, is set up correctly for the investment from day one.

What goes wrong when investors refinance an expiring fixed loan?

The common points of failure:

• › Waiting until after rollover: once the revert rate has applied, the urgency to act dissolves, and the loan sits on a higher rate for months. The three-to-six-month window is where the leverage sits.
• › Ignoring the DTI cap: investors with multiple properties can find that even with strong equity and good rental income, the DTI assessment limits what lenders will write, and the best rate is at a lender whose quota is not exhausted.
• › Missing the tax law changes: the negative gearing restriction on established residential property purchased after 12 May 2026 takes effect from 1 July 2027. Net rental losses on those properties can no longer be offset against salary income from that date. The loan structure, particularly interest-only periods, interacts with this.
• › Applying to the wrong lender first: each application creates a credit enquiry that stays on the file for five years. A decline from a lender whose investor policy didn't suit the application is both a wasted enquiry and a negative signal to the next lender.

Frequently Asked Questions

Does my investment loan revert automatically when the fixed rate expires?

Yes, it reverts to the lender's standard variable rate for investment loans on the expiry date. That revert rate is set by the lender and is rarely the most competitive rate they offer, so acting before expiry gives you the choice.

Is re-fixing with the same lender subject to a serviceability test?

Yes, most lenders run a fresh serviceability assessment when you apply to re-fix, even if you are staying with them. Your income, debts and property values are all reassessed at the time of the new application.

How does the APRA buffer affect refinancing an investment loan?

APRA requires lenders to assess repayments at your actual rate plus 3 percentage points. On an investment rate in the mid-to-high sixes, that means the lender is testing at close to nine percent or above, which reduces the loan amount you can qualify for compared to the original assessment.

Should I fix or go variable when my investment fixed rate expires?

If you value payment certainty and plan to hold the property for the next two to three years, re-fixing can make sense. If you want offset access, flexibility to make extra repayments, or may refinance again soon, variable is usually the cleaner structure, though the rate premium matters.

Does the negative gearing change affect my expiring fixed rate decision?

If you purchased an established residential investment after 12 May 2026, net rental losses cannot be offset against your salary from 1 July 2027. This changes how the loan's interest-only structure and tax position interact, and it's worth discussing with your accountant alongside the refinancing decision.

Is a mortgage broker or my existing lender better for an expiring investment loan?

A mortgage broker, every time. Your existing lender will offer you their own products. A broker compares across 70+ lenders, including how each one treats rental income shading and your DTI position, which is often where the meaningful difference lies.

Your Next Steps

Getting that assessment done before the fixed rate expires is what keeps you in control of the timing and the outcome.

The right lender for refinancing an expiring investment loan depends on your situation, and that's a conversation worth having. Talk to the Serres Property Finance team or call 1800 040 030, and we'll compare your options across 70+ lenders.
