How Many Investment Loans Can You Have in North Brisbane, QLD, The Investor's Guide
There is no rule that says you can only have two investment loans, or five, or ten. What lenders are actually measuring is whether each new loan fits inside your borrowing capacity, and that calculation changes every time you add a property to the portfolio.
Whether you're buying your first investment property in Stafford, scaling a portfolio across Kedron or Mitchelton, or sitting with three properties and wondering whether a fourth is realistic, the answer depends on debt-to-income ratios, serviceability and how you have structured the loans so far.
Our team works with property investors in North Brisbane, QLD at every stage of portfolio growth. Comparing across 60+ lenders is where the difference is made, because lenders count rental income, existing debt and serviceability in different ways, and the gap between the most and least generous is often another property.
Key takeaways
- No legal cap on investment loans; serviceability and DTI are the real limits.
- APRA limits high debt-to-income lending to 20% of new loans at each lender.
- North Brisbane house medians sit above the $1,000,000 FHBG cap across most suburbs.
Is there a limit on how many investment loans you can have in North Brisbane?
No lender or regulator sets a fixed number. What limits your portfolio is whether each new loan passes serviceability assessment, and whether your total debt sits within what lenders are currently allowed to write under the APRA debt-to-income framework. APRA requires that no more than 20% of a lender's new lending goes to borrowers at a debt-to-income ratio of 6x gross income or higher, and investment lending sits at higher DTI ratios on average than owner-occupier lending. That means investors feel the cap before most other borrowers do.
How do lenders actually assess a property investor's borrowing capacity?
Lenders assess each new loan against your total income, your total existing debt, and the projected rental income from every property you hold. They do not simply count how many loans you have. What they are working through is whether your income, after all commitments, can service one more loan at the assessment rate of approximately 9%, which is your actual rate plus the APRA 3.0% buffer.
Rental income is not counted at face value. Most lenders shade it to around 80% of gross rent to allow for vacancies, rates, insurance and management costs. If you hold three properties each returning $600 per week, the lender might count roughly $1,440 per week rather than $1,800, and they'll still add the holding costs on top. That gap compounds quickly across a growing portfolio.
Your credit card limits also factor in. Each card is treated as though it's drawn to the full limit, at roughly 3% to 3.8% of the limit per month, regardless of your actual balance. A $20,000 card that you pay off monthly still reduces what a lender will lend you.
We see a lot of investors who have been told they've hit their limit by one lender, and come to us assuming that's the market's answer. It usually isn't. The same rental income, the same debt, and a different lender's shading policy can unlock another property that the first lender wouldn't touch.

How does the APRA debt-to-income cap affect North Brisbane investors?
From 1 February 2026, APRA requires authorised deposit-taking institutions to limit new lending above a debt-to-income ratio of 6x gross income to no more than 20% of their total new lending. Owner-occupier and investor pools are tracked separately, so a lender can exhaust its investor quota while still writing owner-occupier loans. Non-bank lenders are not subject to the cap, which is one reason the panel matters so much for investors beyond their second or third property.
The DTI calculation uses your total debt, not just your home loan. That includes credit card limits, personal loans, HECS repayments and the new loan itself, all divided by your gross annual income. A portfolio investor with $2.4 million in property debt and a $200,000 income sits at 12x DTI, well above the threshold. That does not mean they cannot borrow, but it does mean the number of lenders still willing to write the loan is significantly smaller.
What the DTI cap means practically:
- › Investor pool: lenders track investor and owner-occupier DTI separately, so investor quota can be exhausted while the lender is still active for home buyers.
- › Non-bank lenders: not subject to APRA's DTI cap, which is why they become relevant at property three, four or five.
- › Timing within a quarter: a lender near its investor quota may decline a file it would have written two months earlier in the same quarter.
- › Existing loans: the cap applies to new lending only; your current portfolio is unaffected unless you refinance.

What does the North Brisbane property market mean for your investment portfolio?
CoreLogic data shows the North Brisbane market has moved sharply. House medians across the approved suburb set run from $753,000 in Bowen Hills up to $2,150,000 in Paddington, and 12-month growth in suburbs like Kedron at 22.48% and Enoggera at 22.00% reflects genuine price movement, not a rounding effect. Unit medians in most suburbs sit well under $1,000,000, with Stafford at $760,000, Mitchelton at $840,000 and Kedron at $805,100.
The practical consequence for portfolio investors is that the loan sizes at entry are large. A 20% deposit on a $1,580,000 Kedron house is $316,000 in cash before costs. At those entry prices, serviceability is the binding constraint far more often than deposit savings, and equity from earlier properties is usually what makes the next purchase possible.

How should investors structure loans as their portfolio grows?
The structure of each loan shapes what you can do next. Cross-collateralising, which means securing two or more properties under the same loan facility, makes the application simpler but ties your portfolio together. Selling one property, drawing equity from another, or refinancing a single loan all require the lender's consent and a revaluation of the whole position.
Standalone loans keep each property independent. You can sell, refinance or draw equity from one without the others being assessed. The trade-off is that standalone loans require each property to carry enough equity to support its own LVR, which is harder to achieve in the early stages of a portfolio.
The options worth weighing:
- › Standalone loans: each property secured independently · sell or refinance one without affecting others · harder to access equity early · cleaner long-term structure
- › Cross-collateralised: simpler at application · lender controls all securities together · complicates every future decision · exit requires full portfolio revaluation
- › Multiple lenders: spreads DTI exposure · avoids one lender's quota running out · more complex to manage · often unlocks property four or five
For most investors building past two properties, standalone loans across multiple lenders is the cleaner structure, even though cross-collateralising looks simpler at application.
What changes with negative gearing from 1 July 2027?
The Treasury Laws Amendment (Tax Reform No. 1) Act 2026 received Royal Assent on 26 June 2026. From 1 July 2027, net rental losses on established residential property purchased after 7:30pm AEST on 12 May 2026 can no longer be offset against salary or other non-property income. The losses are not lost; they are quarantined and can be carried forward against future residential rental income or capital gains.
Property held at 7:30pm on 12 May 2026 is fully grandfathered. New builds are exempt and keep full negative gearing. A granny flat added to an existing property does not count as a new build for these purposes.
The CGT discount for individuals on assets held longer than 12 months is also changing from 1 July 2027, replaced by cost-base indexation and a 30% minimum tax on the remaining real gain. Both reforms are law, not proposals, and neither takes effect before 1 July 2027. Any investor article or conversation about long-term returns should account for them. Talk to your accountant about what this means for your specific portfolio before the commencement date.

When does scaling an investment portfolio stop making sense?
Adding a fourth or fifth property makes sense when the equity from earlier purchases can fund the deposits, the rental income genuinely offsets holding costs, and each loan can be structured so it stands on its own. It stops making sense when serviceability is being carried by optimistic rental assumptions, when the whole portfolio is cross-collateralised so tightly that one vacancy triggers a revaluation, or when the DTI position has moved so far that you have no refinancing options left.
The honest version is that most investors who run into trouble are not over-leveraged in absolute terms. They are inflexible. One loan cross-securing three properties, with one lender, at a rate that is about to expire, leaves very little room to move. Diversifying lenders and keeping structures clean while the portfolio is growing costs a little more in administration and sometimes in rate, but it is usually the difference between a portfolio that can keep going and one that stalls.
If I were building a portfolio today, I'd keep each loan standalone from the start and use a second lender by property three. The short-term admin is worth it. A cross-collateralised portfolio with one lender looks tidy until you want to sell one property, and then it costs you in time, fees and sometimes the deal itself.

What approval challenges do property portfolio investors face?
Where portfolio investors lose ground at assessment:
- › Rental income shading: most lenders count roughly 80% of gross rent, and the gap compounds across three or four properties so the assessed income is far lower than the actual figure on the leases.
- › Lender quota timing: a lender near its investor DTI quota for the quarter may decline a sound application, and reapplying next quarter with a new enquiry on the credit file is a setback that costs more than switching lenders in the first place.
- › Cross-collateral complications: investors who cross-secured earlier properties find that the existing lender's consent requirement slows or blocks later purchases, because any new security triggers a portfolio revaluation.
- › Interest-only rollover: when an interest-only period ends, the loan reverts to principal and interest over the remaining term, which lifts the repayment sharply and can pull the serviceability calculation below the line at renewal.
Frequently Asked Questions
Is there a legal limit on how many investment loans you can have in Australia?
No legal limit exists on the number of investment loans. The real constraints are serviceability assessment and the APRA debt-to-income framework, both of which vary between lenders.
Does the APRA DTI cap apply to non-bank lenders?
No, it applies only to authorised deposit-taking institutions such as banks and credit unions. Non-bank lenders are not subject to the cap, which is why they become relevant for investors at higher DTI ratios.
How do lenders count rental income when assessing a portfolio investor?
Most lenders shade rental income to around 80% of gross rent to allow for vacancies and holding costs. Property expenses are then assessed on top of that reduced figure, so the net assessed rental income is lower than the lease amount.
Is a standalone or cross-collateralised loan structure better for investors?
Standalone loans are generally the cleaner long-term structure. Cross-collateralising is simpler at application but ties securities together, so any future sale or refinance of one property requires the lender to reassess the whole portfolio.
Does negative gearing still apply to North Brisbane investment properties?
Yes, until 30 June 2027. From 1 July 2027, established properties purchased after 7:30pm AEST on 12 May 2026 can no longer offset net rental losses against other income. New builds remain exempt. Talk to your accountant about the impact on your portfolio.
Should I use a mortgage broker or go directly to my current lender for an investment loan?
A mortgage broker, every time. Portfolio investors benefit most from lender comparison because rental income shading, DTI quota and interest-only policies differ significantly. Your current lender is one option, not a benchmark.
Your Next Steps
How many investment loans you can have in North Brisbane depends far less on the number than on the structure, the lenders involved, and how each loan has been set up. The investors who keep growing their portfolios are usually the ones who got the structure right early, spread across more than one lender before the DTI position tightened, and treated the tax reforms as a planning input rather than a surprise.
The right lender for your next investment property depends on your situation, and that's a conversation worth having. Talk to the Kelly Brothers Finance team or call 07 3847 9450, and we'll compare your options across 60+ lenders.
