Refinancing an Investment Property in Brisbane Southside, QLD, What Lenders Actually Check
If your investment loan hasn't been reviewed since you settled, there's a reasonable chance you're paying more than you need to, and possibly borrowing against terms that no longer fit where your portfolio is heading. Refinancing an investment property isn't the same as refinancing the home you live in, and the gap between how lenders treat the two is where most investors either gain ground or leave it on the table.
Across Brisbane Southside, QLD, a sizeable number of investors purchased in the last three to five years when rates were near historic lows. Those fixed terms have rolled, variable rates have moved, and the equity position in most southside suburbs has shifted meaningfully. Whether you're in Annerley, Coopers Plains or Moorooka, the question is whether the equity and income position you're sitting on now opens up better options than you had at purchase.
Our team works with property investors refinancing across Brisbane Southside, comparing across 50+ lenders to find the structure that fits both the property and the broader lending picture.
Key takeaways
- Lenders assess rental income at roughly 80% when calculating your capacity.
- Most Brisbane Southside house medians now sit well above the $1,000,000 scheme cap.
- The APRA DTI cap can limit how much high-ratio investment lending a single lender will write.
Can you refinance an investment property in Brisbane Southside, QLD?
Yes, you can refinance an investment property, and it often makes more sense than refinancing an owner-occupier loan because the financial stakes are higher over a longer hold. The key variable is your equity position and how a new lender will assess the rental income against your total debt picture. CoreLogic data shows strong 12-month growth across Brisbane Southside, with Annerley reaching a median house price of $1,400,000 and Moorooka at $1,368,000, which means investors who purchased three or more years ago are typically sitting on material equity, even after the rate moves of the last two years.

How do lenders assess an investment refinance differently?
Investment loans are assessed on the same core serviceability framework as any other loan, but with two mechanics that reliably produce a different number than an owner-occupier application. Understanding both tells you which lenders are worth approaching and which ones will limit you.
Rental income shading
Lenders don't count your gross rent in full. Most shade it to approximately 80% of the gross figure before adding it to your income, and then add the property's holding costs on top as commitments. That means a property returning $600 a week gross is assessed as contributing closer to $480 before costs come out. The gap between what the property earns and what a lender credits you for is one of the main levers a broker works when finding the right match.
The APRA DTI cap
Since 1 February 2026, APRA limits how much high debt-to-income lending an authorised deposit-taking institution can write. Specifically, no more than 20% of new lending can sit at a debt-to-income ratio of six times gross income or higher. Investor lending tends to sit at higher DTI ratios on average, so the cap bites investors first and hardest. Where one lender's investor pool is near that threshold, they may decline a file they'd have written two months earlier. Non-bank lenders are not subject to the cap, which is why the same application can produce different outcomes depending on which lender sees it and when.
We see investors rule themselves out of a refinance because their current lender quoted a tight number. More often than not, a different lender's rental income treatment or DTI position changes the answer entirely. The capacity isn't fixed, the lender is.

What do you need to qualify to refinance an investment loan?
A strong refinance application for an investment property typically needs to satisfy four things. Where any one is borderline, the lender mix matters more than the rate.
What lenders check:
- › Equity: most lenders want the refinanced loan to sit at or below 80% LVR without LMI. Where the LVR is higher, LMI applies or the lender panel narrows sharply.
- › Rental evidence: a current signed lease or a rental estimate from the managing agent. Lenders want to see the tenancy is genuine and the rent is at or near market.
- › Income and serviceability: your full income picture assessed at approximately 9% (the actual rate plus the APRA 3.0% buffer), including all existing loan commitments and credit card limits.
- › Property type and postcode: some lenders restrict high-density postcodes or specific property types. Outer-ring acreage and very small units face a narrower panel regardless of your financial position.
- › Exit costs on the current loan: break fees on a fixed rate and discharge fees on any loan. These don't stop a refinance but they change the calculation on when it makes sense.

What does it cost to refinance an investment property in Brisbane Southside, QLD?
The costs of refinancing sit in two buckets: what you pay to leave your current lender and what you pay to set up the new one. Discharge fees on most lenders run to a few hundred dollars, and a fixed-rate break fee can be material if rates have moved significantly since you fixed. On the incoming side, application or establishment fees vary by lender, and a new valuation is almost always required.
The routes worth weighing:
- › Rate-and-term refinance: lower rate on similar terms · lower holding cost · no equity release · straightforward assessment
- › Cash-out refinance: access equity above the current loan · funds can be used for another deposit · higher loan balance · re-assessed on the new total
- › Interest-only switch: lower monthly outgoing · typically up to 5 years IO on an investment · higher rate than P&I · principal doesn't reduce
The right structure depends on whether you're holding, building out a portfolio, or planning a sale. That decision is worth a conversation before you approach a lender, because restructuring at refinance is much simpler than restructuring mid-loan.

How long does it take to refinance an investment property?
A straightforward investment refinance typically settles in three to six weeks from application. The timeline stretches when a valuation comes in below expectation, when the property is tenanted and access for a valuer needs to be coordinated, or when the application is more complex, such as where there are multiple properties or trust structures involved.
The single most common delay is a low valuation. Where the lender's valuer comes in below the contract or the owner's expectation, the buyer covers the shortfall in cash or the deal is restructured. On an investment refinance, a lower-than-expected valuation can mean the LVR exceeds 80%, which triggers LMI or narrows the lender panel. Having a realistic market read before lodging, and knowing which lenders on the panel are likely to value conservatively, is where preparation pays off.
When does refinancing an investment property not make sense?
There are three situations where a refinance looks compelling on paper but doesn't stack up on closer examination. A fixed-rate break fee is the most common one: if rates have moved significantly since you fixed, the lender's break cost can exceed two years' worth of rate savings, and the math simply doesn't work regardless of the new rate on offer.
The second is where your equity position has moved the wrong way. An LVR above 80% without significant rental income to absorb LMI into the loan can make a refinance cost more than staying put. The third is timing against a portfolio move: if you're planning to sell within 18 months, the costs of breaking and re-establishing rarely recover in that window. If all three apply and a refinance is still the plan, the structure being sought is probably the driving factor, not the rate, and that's a different conversation.
When an investor comes to us having already decided to refinance, the first thing we do is run the break cost and the full holding-cost comparison. Sometimes the answer is to wait six months and come back when the fixed term expires cleanly. That's not a lost client, that's the right advice.

How to refinance an investment property in Brisbane Southside, QLD, step by step
The process is more straightforward than most investors expect. Four steps, and the first is the only one that involves any real preparation on your part.
Step 1: Talk to us
We start by reviewing your current loan, your equity position and your rental income to work out whether a refinance stacks up and which lenders are worth approaching.
Step 2: Gather your documents and run the numbers
You'll need your most recent lease or rental statement, two recent payslips or your last two tax returns if you're self-employed, and statements on all existing loans. We run the comparison against your break costs and map out the net position.
Step 3: Match to a lender and lodge the application
We submit to the lender whose rental income treatment, DTI position and product structure best fits your situation. A valuation is ordered and the application is assessed.
Step 4: Manage approval through to settlement
We handle the discharge with your outgoing lender and coordinate settlement. Once the loan funds, you're on the new terms and the refinance is done.
What goes wrong when investors refinance?
The three situations where investment refinances fall over:
- › Applying to the wrong lender first: a decline from a lender whose DTI pool is full, or who doesn't like the postcode, leaves a credit enquiry on your file. Knowing which lenders are likely to say yes before you apply is what a broker's panel access is for.
- › Overlooking the cross-collateralisation trap: if your investment and your home are secured together under the same lender, refinancing just the investment loan requires that lender's consent and a revaluation of both. Splitting the securities first gives you genuine flexibility.
- › Treating interest-only as the default: IO reduces the monthly outgoing but doesn't reduce the principal, so DTI stays high for the full IO period. For investors planning to grow a portfolio, that matters, because the next purchase is assessed on the same total debt.
Frequently Asked Questions
Can I access equity when I refinance an investment property?
Yes, a cash-out refinance releases equity above the current loan balance, provided the new total stays within the lender's acceptable LVR, typically 80% without LMI. The released funds can be used for a further deposit or other purposes.
Does rental income count toward my serviceability when refinancing?
It does, but at roughly 80% of the gross rent, not the full amount. Property holding costs are then added as commitments on top, so the net contribution to serviceability is lower than the headline rent figure.
Will the APRA DTI cap affect my investment refinance?
It can. The cap limits how much high debt-to-income lending a bank can write, and investors tend to sit at higher DTI ratios. If your preferred lender's investor pool is near the threshold, they may pass. Non-bank lenders are not subject to the cap and may assess the same application differently.
Is an interest-only or principal-and-interest structure better for an investment refinance?
Interest-only lowers the monthly outgoing but keeps your principal and DTI high across the IO period. P&I reduces both over time and usually comes with a lower rate. Which one fits depends on your cash flow position and whether you're growing a portfolio or holding.
What happens to negative gearing when I refinance?
Refinancing a grandfathered investment property doesn't affect its negative gearing status for properties held before 7:30pm on 12 May 2026. From 1 July 2027, new rules apply to established properties purchased after that date, so confirm your position with your accountant before structuring the refinance.
Should I use a mortgage broker or go directly to my bank for an investment refinance?
A mortgage broker, every time. Investment loans sit at higher DTI ratios, lender rental income treatment differs materially between lenders, and the APRA DTI cap means timing and lender selection both matter. A broker comparing across a panel finds which lender will actually write the loan on the best available terms.
Your Next Steps
Refinancing an investment property in Brisbane Southside, QLD involves more moving parts than a standard home loan review: rental income treatment, DTI positioning, equity levels, break costs and the negative gearing rules all intersect in ways that make lender selection the real decision. Getting that combination right is what changes the financial outcome, not just the rate.
The right lender for your investment refinance depends on your situation, and that's a conversation worth having. Talk to the Evergreen Loan Solutions team or call 0421 152 859, and we'll compare your options across 50+ lenders.
