Interest Only Loans for Investors in North Brisbane, QLD, The 2026 Guide
This article is by Kelly Brothers Finance, North Brisbane Mortgage Brokers . Simply get in touch here if you need finance help.
North Brisbane property investors have access to loan structures that most owner-occupiers never see. Whether you're buying your first investment property or expanding an existing portfolio, interest only loans can significantly improve your cash flow and tax position, but only if you understand which lenders offer the most investor-friendly terms and how the structure actually works in practice.
The right lender makes a genuine difference to your borrowing capacity and ongoing repayments. While some lenders have tightened their investment lending criteria following APRA changes, others actively compete for quality investor business, and that competition translates into better rates, higher loan-to-value ratios, and more flexible serviceability assessment for borrowers who know where to look. Suburbs like Kelvin Grove, Alderley and Stafford are attracting strong investor interest across North Brisbane right now.
Kelly Brothers Finance helps property investors across North Brisbane, QLD compare investment loan options across 60+ lenders, completely free of charge.
Here's what you need to know about interest only loans before approaching any lender in 2026.
Key takeaways
- Interest only periods typically run 1 to 5 years before reverting to principal and interest.
- Competitive investment variable rates start from approximately 5.90% p.a. as of July 2026.
- Lender policies on interest only terms, LVR limits and serviceability vary significantly.
How do interest only loans work for property investors?
Interest only loans let you pay just the interest portion of your loan for an agreed period, typically 1 to 5 years. During this time, the principal balance stays the same, you're not reducing the debt, but you're freeing up cash flow for other investments or to cover holding costs like rates, insurance, and maintenance.
For investors, this structure delivers two key benefits: lower monthly repayments and maximum tax deductions since all interest remains deductible. On a $600,000 investment loan, a 0.30% p.a. rate difference is approximately $1,800 a year, which is exactly why getting the lender match right matters. The exact benefit depends on your loan size, rate, and tax bracket, which is what we work through with you before you commit to any structure.

What tax benefits and investment structures apply to interest only loans in North Brisbane, QLD?
Investors using interest only structures can access several tax advantages that make the structure particularly efficient when managed correctly.
Key benefits to understand:
- › Negative gearing: interest payments and holding costs can be offset against your other income, reducing your overall tax liability.
- › Depreciation benefits: both building depreciation and plant and equipment depreciation can be claimed, even with interest only loans.
- › Capital gains tax discount: properties held for 12 or more months qualify for a 50% CGT discount for individuals.
- › APRA investor caps: banks must limit new investor lending, but non-bank lenders are not subject to the same restrictions, creating opportunities with alternative lenders.

What mistakes do investors make with interest only loans?
The biggest mistake is choosing interest only without understanding the transition. When the interest only period ends, your loan reverts to principal and interest, and the repayments jump significantly. Smart investors plan for this from the start, either by budgeting for the higher repayments or refinancing to extend the interest only period with a different lender.
The second mistake is not comparing lenders properly. Interest only rates can vary by 0.20 to 0.40% between lenders, and the maximum interest only period ranges from 1 year to 5 years depending on which lender you choose. This is exactly why broker comparison makes financial sense, and why lender selection is the most consequential decision an investor makes before signing.
Which North Brisbane suburbs work best for interest only investment strategies?
The best suburbs for interest only strategies combine strong rental demand with capital growth potential.

Milton has shown strong house price growth of +21.21% over 12 months, while Alderley at a $1,683,000 house median offers established family rental demand with 12-month growth of +20.43%.
Strategy by suburb type:
- › Entry-level strategy: Kelvin Grove and Windsor units under $800,000, strong rental demand and manageable entry cost.
- › Growth-focused strategy: Milton and Alderley houses, higher entry cost but strong recent capital growth trajectory.
- › Yield-focused strategy: Wooloowin and Enoggera, balance of affordability and established rental markets.
- › Portfolio expansion: Stafford and Kedron, mid-range prices with consistent rental demand and growth potential.

Frequently Asked Questions
What interest only rates are available for investors in North Brisbane in 2026?
Competitive investment variable rates start from approximately 5.90% p.a. as of July 2026. Interest only rates are typically 0.10 to 0.30% higher than principal and interest rates with the same lender, but this varies significantly across our 60+ lender panel.
Can investors get interest only for the full loan term?
No, interest only periods are temporary, typically 1 to 5 years depending on the lender. After this period, the loan automatically converts to principal and interest repayments, which increases your monthly payments and is worth planning for well in advance.
Do investors need a bigger deposit for interest only loans?
Most lenders require at least a 20% deposit for investment properties, and some restrict interest only loans to borrowers with 25 to 30% deposit. However, some specialist lenders offer interest only with 10% deposit for investors with strong income and credit history.
What happens when the interest only period ends on an investment loan?
Your loan converts to principal and interest repayments over the remaining loan term, which typically increases your monthly repayments by a meaningful amount depending on your loan balance and remaining term. Planning ahead with your broker before the period expires avoids any disruption to your cash flow.
Can investors extend their interest only period?
Yes, but it requires lender approval and may involve refinancing to a new lender if your current lender won't extend. We help investors plan these transitions well before the interest only period expires to ensure continuity.
Should investors use a mortgage broker or go direct to a bank for interest only loans?
A mortgage broker, every time. Investment lending policies vary dramatically between lenders, some have tightened criteria significantly while others actively compete for investor business. Comparing 60+ lenders finds the best combination of rate, loan-to-value ratio, and interest only terms for your specific situation.
Are interest only loans worth it for smaller investment properties in North Brisbane?
It depends on your cash flow needs and tax position. Even on smaller loans, interest only can improve monthly cash flow by a useful margin, which helps cover holding costs and reduces out-of-pocket expenses. The benefit increases with loan size and your marginal tax rate.
Your Next Steps
Your investment loan structure affects both your immediate cash flow and your long-term wealth building strategy. Interest only loans can significantly improve your holding costs and tax position, but the terms vary substantially between lenders, and getting this right from the start saves you thousands over the loan term.
The right lender for an interest only investment loan 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 at no cost to you.
