Is an Interest-Only Loan Right for You? Wollongong, NSW Property Guide

October 21, 2025

Wollongong, NSW is quickly becoming one of the most sought-after property markets in Australia. With its coastal lifestyle, growing infrastructure, and proximity to Sydney, it offers a strong mix of lifestyle and investment potential.


For some homebuyers and investors, an interest-only loan could be a smart way to enter the Wollongong market, especially when looking to manage cash flow in the short term.


Wollongong mortgage brokers from SimpleFin can help you assess whether an interest-only loan suits your goals. With access to multiple lenders and expert knowledge of the local Wollongong property landscape, our brokers can make the interest-only loan process more efficient and tailored to your needs.


Let’s break down what interest-only loans are, who they benefit, and what you need to consider before deciding.




What is an Interest-Only Loan?


An interest-only loan is a type of mortgage where you only pay the interest portion of the loan for a set period, usually 1 to 5 years. After this, the loan reverts to a principal-and-interest loan, where you start repaying both the borrowed amount and interest.


This structure means lower repayments during the interest-only period, which can be attractive if you’re:


  • An investor looking to maximise tax-deductible interest.

  • A buyer wanting lower upfront repayments while your income stabilises.

  • Planning to sell the property before the principal payments begin.

However, because you're not reducing the loan principal initially, the total cost of the loan over time can be higher than a standard loan. This is especially important to factor in if you plan to hold the property long term.


These loans can carry more risk if property values fall or if you can’t switch easily to principal-and-interest later on.



Who Should Consider an Interest-Only Loan in Wollongong?


Wollongong's property market has seen consistent growth due to its combination of coastal appeal, education hubs, and infrastructure investment. This makes it attractive to:


  • Property investors seeking capital growth.

  • First-time buyers needing lower repayments in the early years.

  • Homeowners expecting a future income increase.


For investors, an interest-only loan allows them to keep repayments low while potentially claiming the interest as a tax deduction. This is especially useful if they're focused on rental yield and capital gains from Wollongong’s growing property market.


However, it’s not a one-size-fits-all solution. Interest-only loans can be risky if property values drop or if you struggle with higher repayments once the interest-only period ends.


The Reserve Bank of Australia (RBA) notes that borrowers need to be aware of the long-term repayment impact. It's crucial to have a clear strategy and to know when you’ll start paying off the principal.



Pros and Cons of Interest-Only Loans


Like all financial tools, interest-only loans come with both advantages and risks. Here’s a quick overview:


Pros:


  • Lower monthly repayments during interest-only period.

  • Free up cash for renovations, other investments, or emergencies.

  • Suitable for investors focused on capital growth and tax offsets.

Cons:


  • No reduction in loan balance during interest-only phase.

  • Higher total interest over the life of the loan.

  • Increased repayments after interest-only period ends.

  • Risk of negative equity if property prices fall.


If you’re unsure, consider using a loan repayment calculator to compare interest-only versus principal-and-interest repayments.


How Interest-Only Loans Compare to Principal-and-Interest Loans


While interest-only loans offer short-term savings, principal-and-interest loans provide long-term benefits like reducing the loan balance and overall interest paid.


For example, with a $600,000 loan at 6% interest over 30 years:


  • Interest-only (5 years): You’ll pay only interest for the first 5 years, then face higher repayments when switching to principal-and-interest for the remaining 25 years.

  • Principal-and-interest: You start reducing your debt immediately, paying less interest over time.


This distinction matters especially in Wollongong’s market, where prices continue to rise. If your goal is long-term ownership, building equity sooner could be more beneficial.


On the other hand, investors may prioritise cash flow and tax strategies, making interest-only loans more suitable for their portfolio.



Alternative Options to Interest-Only Loans


If you’re unsure about committing to an interest-only structure, there are alternative paths:


  1. Split loans: Combine fixed and variable interest rates or interest-only and principal-and-interest components.

  2. Offset accounts: Reduce the interest charged on your home loan with your savings.

  3. Redraw facilities: Access extra repayments if needed.

These features can be part of a loan that suits your long-term strategy better than a pure interest-only loan. Speak to your mortgage broker about building a loan package that matches your financial goals.
