Buying a property is one of the most powerful ways to build long-term wealth, but if you get the finance side wrong, it can end up costing you thousands.
Whether you're a first-time investor or growing your portfolio, securing the right investment property loan in Brisbane is just as important as choosing the right property. Unfortunately, many Brisbane investors make avoidable mistakes that hurt their cash flow, limit borrowing capacity, or even lead to loan rejection.
In this blog, we'll break down the most common financing mistakes—and show you how to avoid them—so you can invest in Brisbane property with confidence.
1. Not Getting Pre-Approval First
One of the biggest mistakes is jumping into property hunting before securing loan pre-approval. Without it, you risk falling in love with a property you can’t afford—or losing out to another buyer who’s ready to go.
Pre-approval gives you a clear budget and makes your offer more attractive to sellers. It also helps uncover any issues early, like a low credit score or insufficient deposit.

2. Choosing the Wrong Loan Type
Not all loans are created equal. Some investors lock themselves into the wrong loan structure—like a fixed rate when they need flexibility, or a principal and interest loan when they really needed cash flow from an interest-only option.
It’s important to weigh up the pros and cons of different options. Our guide to fixed vs variable investment loans explains the key differences and which one might suit your goals.
You might also consider a split loan to balance certainty and flexibility, something a broker can help structure for your needs.
3.Overestimating Rental Income
Many property investors make the mistake of overestimating how much rent they’ll receive and how often their property will be occupied.
Lenders typically only include70–80% of expected rental income when assessing your borrowing power. They account for vacancy rates, maintenance, and unexpected expenses.
To avoid cash flow stress, use conservative figures and always allow a buffer in your calculations. Remember that Brisbane’s property market still offers solid yields, but income can vary by suburb and property type.
4. Underestimating Property Expenses
Investment properties come with ongoing costs like:
- Council rates and water bills
- Insurance
- Repairs and maintenance
- Property management fees
- Loan repayments and interest
Ignoring these costs upfront can seriously affect your cash flow. When investing in Brisbane property, be sure to factor in these expenses and plan for the unexpected.
5. Relying on One Lender or the Big Four
Sticking with your everyday bank might feel convenient, but it’s not always the smartest move. Every lender has different policies for investment loans, and you could be missing out on better rates, higher borrowing capacity, or features like offset accounts.
Working with a mortgage broker specialising in investment property loans in Brisbane gives you access to a wide range of lenders and the knowledge to match you with the right loan product.
6. Not Structuring the Loan Correctly
Loan structure isn’t just about the rate; it’s about how the loan works for your strategy.
Do you want interest-only repayments for better cash flow? Will an offset account help you reduce interest while keeping funds accessible? Are you protecting your tax position and personal assets?
A well-structured loan supports your investment goals now and into the future. Poor structure, on the other hand, can lead to lost tax benefits, higher costs, and refinancing headaches.

7. Trying to Time the Market
Some investors sit on the sidelines waiting for the “perfect” moment. However, experienced investors know that property is a long-term investment, and time in the market often matters more than timing it perfectly.
Despite rising rates, Brisbane is still a hotspot for property investment, thanks to its lifestyle appeal, infrastructure projects growth, and solid rental demand. Learn more in our blog on why Brisbane remains a smart place to invest, even with rising interest rates.

They’ll also help you navigate the application process smoothly and avoid delays or rejections.
