Interest-Only Home Loans: Are They Right for You?
If you need home, car or business loan help, just get in touch here.
Interest-only home loans can feel like a lifesaver amid rising mortgage repayments and cost-of-living pressures.
In Brisbane, where property prices jumped over 10% by late 2024, they’ve become a smart option for buyers needing breathing room and investors chasing better rental yields heading into 2025. With lower upfront repayments, interest-only loans free up cash while your property grows in value.
If you’re planning to live or invest in Brisbane, the mortgage brokers at Kelly Brothers Finance can guide you through the ins and outs, ensuring this loan type fits your goals. With local insight and access to multiple lenders, they’ll help you compare options and avoid costly missteps.
Let’s explore how interest-only home loans work, and whether they’re right for you.
What Is an Interest-Only Home Loan?
An interest-only home loan is a type of mortgage where, for a set period, you only pay the interest charged on the loan amount, not the principal. During this time, your loan balance doesn't reduce, but your monthly repayments are lower compared to standard home loans.
How It Differs from Principal & Interest Loans
With a principal and interest loan, each repayment reduces both the principal loan amount and the interest, helping you build equity from day one. In contrast, interest-only loans delay paying down the principal, keeping repayments lower but increasing the overall cost over time.
Typical Term Lengths for Interest-Only Periods
- 1 to 5 years is standard for most lenders
- Some may offer up to 10 years (with strict conditions)
- After the interest-only term ends, repayments switch to principal & interest
This structure can offer short-term relief, but it's not suited to everyone. Hence, it’s best to consult with trusted Brisbane mortgage brokers to see if it aligns with your goals.
How Do Interest-Only Home Loans Work?
In an interest-only home loan, your monthly repayments only cover the interest charged on your loan amount, not the principal. That means your loan balance doesn’t reduce during this time.
Here’s how it works in simple terms:
- Loan amount: $600,000
- Interest rate: 6%
- Monthly repayment (during interest-only period):
$600,000 × 6% ÷ 12 = $3,000 per month
This repayment structure can feel like a financial breather, ideal for those who want to manage cash flow or direct money toward other expenses or investments.
What Happens After the Interest-Only Term Ends
Once the interest-only period ends (usually after 1 to 5 years), the loan automatically switches to a principal and interest repayment structure—unless you refinance or negotiate an extension.
This means you’ll start repaying both:
- The original loan amount (principal)
- Ongoing interest charges
Because you now have less time to repay the principal (e.g. 25 years instead of 30), your monthly repayments will increase noticeably.
Impact on Total Loan Cost Over Time
Interest-only loans reduce repayments in the short term, but they come at a long-term cost. Here’s what that looks like in practice:
- Over 5 years on an interest-only loan at 6%, you’d pay $180,000 in interest and still owe the full $600,000
- If you had gone straight onto principal & interest repayments, you’d have repaid around $55,000 of the loan, and paid less total interest
This means you’ll end up paying more interest overall, because the loan balance stays higher for longer.

Who Should Consider an Interest-Only Home Loan?
Not every loan suits every borrower. But in the right hands, interest-only loans can be a smart and strategic tool. Here’s who they might work well for:
- Property investors – Looking to maximise cash flow, claim tax deductions, or use rental income to cover interest.
- Short-term homeowners or renovators – Planning to sell or upgrade the property before the interest-only term ends.
- Borrowers expecting a future income boost – Anticipating a higher salary or business income that will make full repayments easier later.
- Buyers with a clear exit strategy – Those who have a plan to refinance, sell, or switch repayment types before costs increase.
If you're in one of these groups, an interest-only loan might just suit your financial game plan.
Pros and Cons of Interest-Only Home Loans
Interest-only loans offer flexibility—but they’re not without trade-offs. Before choosing this loan type, it’s worth weighing both sides.
✅ Pros
- Lower repayments upfront – Frees up cash during the interest-only period.
- More control over cash flow – Especially helpful for property investors.
- Potential tax benefits – For investment properties, interest may be tax-deductible.
❌ Cons
- Higher total interest paid – You’ll pay more over the life of the loan.
- No equity built – Loan balance stays the same during the interest-only period.
- Tighter approval rules – Lenders apply stricter criteria and risk assessments.
Choosing interest-only is less about saving now, and more about fitting it into your bigger financial picture.
How to Qualify for an Interest-Only Home Loan
Qualifying for an interest-only loan in Brisbane isn’t impossible, but it does take planning. Lenders want to see you're financially prepared and understand the structure.
Here’s what you’ll need to meet the eligibility criteria:
1. Strong Proof of Income and Stability
Lenders assess your taxable income, employment status, and job stability. This shows you can meet your monthly payments, even when the loan rate increases after the interest-only rate period ends.
2. Good Credit Score and History
Brisbane lenders expect a solid credit score, clean repayment history, and no recent defaults. They’ll also review other loan contracts, credit cards, and applications for credit to ensure you're not overcommitted.
3. Clear Financial Goals and Repayment Strategy
You’ll need to demonstrate a plan to manage the loan beyond the interest-only period of time, whether through extra repayments, refinancing, or property sale. A broker can help you match your financial goals with the right loan options.
4. Acceptable Loan-to-Value Ratio (LVR)
A lower LVR (ideally under 80%) improves approval chances and avoids Lenders Mortgage Insurance (LMI). High LVRs may still be accepted, but LMI adds an extra cost to your loan product.
5. Strong Repayment Capacity
Lenders calculate your ability to repay the loan based on loan interest rates at the end of the interest-only term. They'll look at whether you can handle loan repayments under principal & interest, not just the initial rate home loan.
6. Documentation and Property Valuation
You’ll need to submit payslips, tax returns, ID, and bank statements. A property valuation is required to confirm that your security aligns with the loan terms and supports the requested loan amount.
7. Type of Property and Loan Features
Some loan options offer offset accounts, additional repayments, or fee waivers on certain conditions. Brisbane lenders may be more flexible if the property is an investment home loan in a growth suburb with strong rental demand.
8. Fixed or Variable Rate Selection
You'll also need to choose between a variable rate loan and a fixed option. A variable interest rate may offer flexibility for extra repayments, but fixed rates provide repayment certainty over the rate period.

Frequently Asked Questions (FAQs)
Can you put your home loan on interest only?
Yes, many lenders still offer interest-only repayments on secured loans, provided you meet their lending criteria and pass a credit check during the loan application process. You'll need to show that the loan suits your financial strategies and can be sustained beyond the interest-only loan period.
Is it worth doing an interest-only mortgage?
It can be—especially for investors using negative gearing, or business owners needing cash flow flexibility. However, it’s a serious financial decision, and comparing your rates, standard interest rates, and potential savings with a financial advisor or loan specialist is key.
What are the pitfalls of interest-only mortgages?
The main risk is that your principal balance doesn’t reduce during the loan period, so you’ll likely pay more interest over time. Plus, if official cash rate changes by the Reserve Bank of Australia, your variable home loan may spike, creating financial stress down the line.
What is a main disadvantage of the interest-only loan?
You won’t build equity during the interest-only rate term, and you’ll need to make up for it with higher repayments later. This can limit your borrowing power for future loans or refinances, especially if your borrowing capacity has changed.
How much deposit do you need for an interest-only mortgage?
Most financial institutions prefer a 20% deposit to avoid loan fees like Lenders Mortgage Insurance, though some eligible home loans allow less with tighter credit approval criteria. Your deposit size can also influence your comparison rate and determine whether you're offered a basic loan or one with more flexible loan structures.
Are banks still doing interest-only mortgages?
Yes, many major banks and lenders still offer interest-only repayment options on owner-occupied properties and investment loans, though these are usually subject to stricter lending criteria. You’ll need to justify the structure with clear financial advice, a strong loan application, and possibly a shorter loan term.
