Renting vs. Buying: Are You Just Swapping Your Landlord for a Bank?
27 June 2025

It’s a common saying you’ve probably heard a thousand times: "Renting is just paying off someone else's mortgage." While that's often a conversation starter, it's a bit of an oversimplification. You might be thinking, "Sure, but if I take out a 30-year loan, I'm just paying the bank a mountain of interest instead. What's the real difference?"
That's a fair question. When you look at the total interest paid over the life of a long-term mortgage, it can be a staggering figure, sometimes close to the original loan amount itself. So, are you really better off? Let's break it down.
The Long Game: Your Mortgage vs. Never-Ending Rent
One of the most significant differences between a mortgage and rent is the long-term outlook. Your mortgage has an end date. While interest rates can fluctuate on a variable loan, the principal amount you borrowed is fixed. Over time, as your income likely increases with inflation and career progression, your mortgage repayments will become a smaller and more manageable portion of your budget. Eventually, they will disappear altogether.
Rent, on the other hand, is a lifelong expense that typically rises with inflation. What seems affordable today could become a significant financial burden in 10, 20, or even 30 years. To put it in perspective, think about what rent was like a few decades ago compared to now. That upward trend is unlikely to change. When you buy, you're essentially locking in a significant portion of your housing costs for the future.
Furthermore, a portion of your mortgage repayment goes towards paying down the principal, which is the amount you actually borrowed. This is a form of forced savings, building your equity with each payment. When you rent, 100% of your payment is an expense with no return.
Building Your Wealth and a Place to Call Home 🏡
Beyond the numbers, owning a home offers a level of security and stability that renting simply can't match. You have the freedom to renovate, paint, and truly make the space your own without seeking a landlord's permission. You won't have to worry about lease renewals, rent hikes, or the owner deciding to sell, forcing you to move on short notice. This is especially important as you get older and the thought of being forced to find a new rental on a fixed income becomes a daunting prospect.
From a financial standpoint, owning a home is also a significant way to build wealth. Historically, property values in Australia have appreciated over the long term. This means that in addition to the equity you're building through repayments, the value of your asset is also likely to grow. This provides you with financial leverage you can use in the future, whether it's for further investment or to fund your retirement.
It's Not Always a Straightforward Win
Of course, buying a home isn't without its own set of challenges and risks. There are significant upfront costs like a deposit and stamp duty. Ongoing expenses such as rates, insurance, and maintenance are your responsibility. If something breaks, you're the one who has to fix it.
There's also the opportunity cost of your deposit. That money could have been invested in other assets like shares, which may offer different growth potential. The key difference, however, is that it takes a great deal of discipline to consistently invest the difference between your rent and what a mortgage would cost. For many, the structured nature of mortgage repayments is a more reliable way to build wealth.
The Bottom Line
While it's true that a significant amount of interest is paid on a mortgage, it's the price of securing a valuable asset that, for most, will appreciate over time and provide a stable home. Renting offers flexibility, but it's a perpetual expense that will likely increase, and it doesn't contribute to your long-term wealth in the same way.
The decision to buy is a personal one that depends on your financial situation, lifestyle, and long-term goals. But when you look beyond the initial shock of the total interest paid and consider the long-term financial and personal benefits, it becomes clear why buying a home is still considered a cornerstone of financial security for many Australians.
