40-Year Mortgages Are Becoming More Common
Buying a home is becoming more and more challenging for many people across Australia. The goal is there. The deposit may be building. The problem is that what needs to stack up in a home loan assessment is tight relative to purchase prices, income, and everyday expenses.
That is why longer loan terms are starting to get more attention.
From my perspective as a mortgage broker, a 40-year home loan doesn’t solve affordability problems. It is moreso a workaround that comes with compromises.
Even so, it is not something I would automatically dismiss. In the right situation, it can help some borrowers find a way forward.

What A 40-Year Home Loan Actually Changes
It’s all about time.
A 40-year home loan doesn’t make the loan amount any smaller. What it does is give you more time to repay the loan.
When the loan is spread over a longer period, the minimum repayment is spread out further, which lowers the repayment size. That can matter when property prices are high and a standard 30-year loan term requires higher repayments, leaving less room in the budget.
Some borrowers may be close, but because the loan still needs to meet responsible lending obligations, brokers and lenders cannot treat close enough as good enough.
The trade-off is that the debt usually reduces more slowly. If the loan is held for the full term and only minimum repayments are made, the total interest cost can be higher. More interest means the loan costs you more, which means a longer term can make the loan more expensive overall.
So the longer term changes the shape of the loan. It may lower the repayment today, while also affecting the debt position over time.
It Still Needs To Be Affordable
A lower repayment can make a loan look easier to manage, but when we zoom out, the loan still needs to make sense.
As a borrower, you still need to carry the repayment, living costs, existing debts, future changes, and the overall cost of the loan.
As an ethics-first mortgage broker, I believe that a 40-year term should not be used to get a loan approved just because repayments are tight with a shorter term. If the only way the loan works is by stretching it as far as possible, that needs a careful look.
The question is whether the longer term supports a realistic borrowing position as part of a careful plan, not whether it only makes the repayment manageable today.
The Exit Plan is Important
The decision to use a 40-year home loan term should have a plan behind it.
For some borrowers, that plan may be about getting into the market sooner, or being able to buy at all, and home ownership is their main goal. For others, it may be about managing early cashflow, supporting a family situation, or creating room while income, expenses, or circumstances change.
The next question is what happens later. In my professional opinion, a 40-year home loan is not a set-and-forget option. It needs to be reviewed and managed carefully with the help of a switched-on broker.
If your income improves, expenses settle, the property grows in value, or there is more room in the budget, the loan should be reviewed. That may mean making extra repayments, refinancing, shortening the loan term, restructuring the loan, or simply checking whether the original reason for the 40-year term still applies. At BrightCredit, we include this as part of our normal annual review process.
From my perspective, that is the key difference between using a longer term carefully and just stretching the debt. The longer term should support the plan, not become the plan unless completely necessary.
Good Broker Guidance Matters
Making a 40-year home loan work for your situation is about more than finding a lender that offers one and getting approved. The lender you approach, the way the application is presented, your situation, and the way the loan is set up can all affect the outcome.
It is also possible that you may not even need to go with a 40-year home loan. Sometimes the better path is a different lender, a different loan setup, or a clearer way to explain the application. You do not always know what options are available until the full position has been worked through properly.
Once the right path is clearer, the application still needs to be positioned properly. The approach taken can directly influence things like the rate, loan terms, conditions, repayment type, and how much flexibility you may have after the loan settles.
As brokers who specialise in non-standard situations, we help you understand the options before anything is submitted. We work through the details so the lender is approached with the right context and the loan is framed properly from the start. The goal is to make a complex process easier to navigate and help work toward an outcome that fits your position.
Questions To Ask Before Choosing A 40-Year Home Loan
Before choosing a 40-year home loan, it is worth slowing down and asking what the longer term is really doing for you. Yes, a lower repayment can be useful, but it should not be the only reason for choosing the loan.
Some useful questions include:
- Why am I considering a longer loan term?
- Is this helping me buy a suitable home, or pushing me toward a bigger loan?
- What is the repayment difference compared with a shorter term?
- What could the loan cost over the longer term?
- Can I make extra repayments if my position improves?
- When should the loan be reviewed?
- What happens if my income, expenses, or interest rates change?
- Is there a plan to reduce, refinance, or restructure the loan later?
The answers matter because a 40-year home loan should support the wider borrowing decision. It should not just make the repayment look better on the day you apply.
Find Out Where You Stand
A 40-year home loan can be useful in the right situation, and it should have a clear reason behind it.
The lower repayment is only one part of the decision. The loan still needs to make sense around your wider position, the cost over time, and the plan after approval. Depending on the loan size, rate, and how long the loan is held, the extra interest can be significant, sometimes reaching hundreds of thousands of dollars, so it’s worth getting right.
We can help you look at the numbers, understand what may fit, and work through whether a longer loan term is worth exploring.
