Property prices across Australia are pushing new limits, and with interest rates shifting often, many buyers are feeling stuck. Cash flow is no longer a nice-to-have; it’s what makes or breaks your ability to invest and grow a portfolio.
This is where 10-year interest-only loans from AMP and ANZ come into the picture. These loans aren’t new, but they’re being rediscovered by savvy investors who understand how to make the numbers work in their favour. For some, the idea of not paying down the loan principal feels risky. But used with the right strategy, these products can unlock real advantages.
We’re going to explore how these long interest-only periods, once seen as unusual, are now becoming a tool for scaling faster, reducing holding costs, and freeing up household budgets. If you’ve been sitting on the sidelines waiting for the “right time,” this could be the edge you’ve been looking for.
Why Interest-Only Loans Are Back in Focus
A tool for flexibility, not just affordability
AMP has brought back the 10-year interest-only loan, and it’s caught the attention of smart investors across Australia. ANZ and a few smaller lenders have had similar options for a while, but AMP’s move signals a growing shift in how we think about finance.
This type of loan isn’t just about making repayments cheaper. It gives investors breathing room. Instead of chipping away at the principal from day one, you’re keeping your weekly or monthly costs down, often low enough that the rent covers most or all of it. That extra cash flow can be redirected into other investments, renovations, or just easing the pressure on your budget.
While many still default to principal and interest as the “safe” path, interest-only loans are proving to be far more than a short-term fix. They offer flexibility that can unlock faster growth, especially when used as part of a clear property strategy.
Three Strategies That Can Grow Your Wealth Faster
1. Cut Your Holding Costs to Almost Nothing
The biggest draw of a 10-year interest-only loan is what it does for your cash flow. By paying interest only, you’re not chipping away at the loan principal, which keeps your repayments much lower. That means more of your rental income stays in your pocket.
Now pair this with the right property, something with a 6% to 7% rental yield, which you can still find in parts of regional Victoria or Queensland. Suddenly, your property might be close to neutral or even positive cash flow from day one.
Even if you’re slightly negative for the first few years, rising rents and falling interest rates can flip that quickly. Hold that same $500,000 property for 10 years and, if it grows to $1.2 million, you could walk away with hundreds of thousands in gains all without sinking huge amounts of your own cash each year.
2. Refinance for Another 10 Years
Here’s something most investors miss: that 10-year interest-only period? You might be able to extend it.
Once the first decade is up, and assuming your financials check out, many lenders are open to refinancing for another five or even ten years. And this time, your property is probably already giving you solid rental income, so the cash flow from year one of the extension could be strong.
You’re now holding an appreciating asset that’s covering its own costs and giving you surplus income. That extra time in the market could add another layer of growth, especially in rising cycles.
3. Scale Up Without Crushing Your Budget
This is where things get interesting.
Let’s say you’ve got the capacity to borrow enough for one investment property with principal and interest repayments. Now imagine if, instead, you used interest-only loans to hold two or three properties.
Because you’re not repaying the principal, your holding costs drop and your ability to control more assets goes up. With the right choices, those properties grow over the next 10 years, and each one builds equity.
Would you rather hold one $500K property that grows to $1.2 million or three of them? Scaling smartly means your wealth isn’t tied to a single bet. You’re spreading opportunity while keeping your cash flow manageable.
What About the Risks?
Interest-only loans aren’t perfect. Like any strategy, there are a couple of trade-offs to weigh up before jumping in.
1. Slightly Lower Borrowing Power
One thing to keep in mind is that some lenders may scale back your borrowing capacity a bit when you choose interest-only repayments. Since you’re not reducing the loan balance, banks apply slightly more conservative calculations.
This doesn’t always mean you can’t borrow enough to make your plan work; it just means you might need to look at different lenders or adjust your strategy to fit.
2. Higher Interest Rate
Interest-only loans usually come with a small rate premium, often somewhere between 0.3% and 0.5% higher than principal and interest loans.
On paper, that sounds like a downside. But when you run the numbers, the picture changes. If your property grows by $300K to $500K over the next decade, a few thousand dollars in extra interest is just a rounding error. You’re not borrowing for the rate, you’re borrowing for the potential return.
What really matters is the size and quality of the assets you’re holding. One good move today could add serious strength to your financial future.
Final Thought: It’s About Strategy, Not Sacrifice
Paying off debt gives people a sense of security and that’s understandable. But when you look at the numbers, growing your wealth through smart use of leverage often puts you in a much stronger position over time.
The goal isn’t just to own one property outright. It’s to build a portfolio that works for you, brings in income, and sets you up for financial freedom sooner rather than later.
Interest-only loans, especially with long terms like AMP’s 10-year option, offer a chance to do exactly that. When used well, they give you flexibility, control, and breathing room to make better moves. The trick is staying focused on the bigger picture and having a plan that supports your goals.
At the end of the day, investing is a long game. Strategy beats sacrifice every time.
