Downsides of Refinancing a Mortgage in Australia

When it comes to managing our finances, we all want to make the best decisions possible. One of these decisions could be refinancing your home loan. But what does that mean, exactly? Well, in a nutshell, refinancing a home loan in Australia involves replacing your existing loan with a new one. This can be done by switching lenders, changing the length of your loan term, or opting for different repayment options. Sounds simple enough, right? But, like most financial decisions, it's not without its risks and costs.

Refinancing is a common practice in Australia. Many borrowers switch lenders or loan types to get a better deal. It's like shopping around for a new phone plan or insurance policy - you want to make sure you're getting the most bang for your buck. But it's not a decision to be taken lightly. It requires thorough research and a good understanding of your personal financial situation and goals.

Now, let's delve a bit deeper into the world of refinancing. There are two types of refinancing: external and internal. External refinancing is when you switch to a new lender, while internal refinancing involves changing your loan terms with your current lender. Both options have their pros and cons, and the best choice will depend on your individual circumstances.

Why do People Refinance?

There are several reasons why refinancing is a good option. One of the main ones is to secure a lower interest rate. This can reduce your monthly repayments, freeing up some of your income for other expenses. Refinancing can also allow for a reduction in the length of your loan. This means you could potentially own your home outright sooner. Additionally, refinancing can give you access to your home equity, which you can use for things like home renovations or investing. Some people also refinance to take advantage of new loan features, such as offset accounts or redraw facilities.

Another aspect of refinancing that's worth understanding is variable-rate mortgages. These are loans with an interest rate that changes over time. They can be beneficial for those planning to sell their house before the rate adjusts. This is because they often start with a lower interest rate than fixed-rate mortgages. However, they also come with the risk of the interest rate increasing in the future.

Costs to Refinance

Now, let's talk about the costs of refinancing. It's not a free process, unfortunately. There are several fees you might have to pay, including application fees, legal fees, discharge fees, and potentially exit fees. Application fees are what you pay to your new lender to process your loan application. Legal fees cover the cost of the legal work involved in setting up the new loan. Discharge fees are what you pay your current lender to close out your existing loan. And exit fees are any penalties your current lender might charge you for leaving your loan early.

Another cost to consider is Lenders Mortgage Insurance (LMI). This is a type of insurance that protects the lender in case you default on your loan. If you have less than 20% equity in your home, you may have to pay LMI when you refinance. This can add a significant amount to the cost of your loan.

In addition to these costs, there are also risks involved in refinancing, that you should consider.

Risks of Refinancing

Refinancing a mortgage can seem like a great idea, especially when you're promised lower interest rates and reduced monthly repayments. However, it's not without its risks. One of the most significant risks is the potential increase in debt levels. When you refinance, you're essentially taking out a new loan to pay off your existing one. If you're not careful, you could end up borrowing more than you initially owed, especially if you decide to cash out some of your home equity or extend your loan term.

Another risk is the uncertainty surrounding future interest rates. While it's true that refinancing can provide you with a lower interest rate now, there's no guarantee that rates won't rise in the future. If you switch from a fixed-rate loan to a variable-rate mortgage, you could end up paying more in interest over the life of your loan if rates increase.

Lastly, refinancing may incur fees from your current lender. These can include discharge fees, application fees, and potentially even exit fees if your loan contract includes them. These costs can add up, and if they're not factored into your calculations, you could end up paying more than you anticipated.

Alternatives to Refinancing

Before you decide to refinance, it's worth considering other options. One such option is debt consolidation. This involves combining all your debts into one loan, potentially with a lower interest rate. This can simplify your repayments and potentially save you money in the long run.

Another alternative is negotiating better terms with your current lender. If you're a good customer, your lender may be willing to adjust your interest rate or loan terms to keep your business. This can save you the hassle and cost of refinancing.

You could also consider paying extra towards your principal balance. This can reduce the amount of interest you pay over the life of your loan and help you pay off your mortgage faster.

Lastly, improving your budgeting can help you manage your mortgage repayments more effectively. By keeping track of your income and expenses, you can identify areas where you can cut back and put more money towards your mortgage.

Making the Decision to Refinance

Deciding whether to refinance is a big decision that should not be taken lightly. Your personal financial situation and goals play a significant role in this decision. If you're struggling with high-interest debt, for example, refinancing to consolidate your debts may be a good option.

However, it's crucial to do thorough research before deciding to refinance. This includes understanding the terms of your new loan, calculating the total cost of refinancing, and considering the potential risks.

The Australian Competition and Consumer Commission (ACCC) has reported that refinancing could save borrowers significantly. However, it's important to remember that these potential savings should be weighed against the costs and risks of refinancing. If you need help, speak to one of the top mortgage brokers like Principal Mortgages who can guide you through the process.


Refinancing a mortgage in Australia can offer many benefits, but it's not without its downsides. The potential increase in debt levels, uncertainty surrounding future interest rates, and fees from your current lender are all risks that need to be considered.

Alternatives to refinancing, such as debt consolidation, negotiating better terms with your current lender, paying extra towards your principal balance, or improving your budgeting, can also be effective ways to manage your mortgage.

In the end, the decision to refinance should be based on your personal financial situation and goals, and should only be made after thorough research. While the ACCC has reported potential savings from refinancing, it's important to weigh these against the potential disadvantages and risks.

Understanding the downsides of refinancing a mortgage in Australia is crucial before making such a significant financial decision. By being aware of these potential pitfalls, you can make an informed decision that best suits your financial situation and goals.
