Do Interest Only Home Loans Still Make Sense?

Six months ago interest only loans made a lot of sense for property investors. Today, the story is very different.

18 years ago I was living out of a tent, in a little village named Balibo, on the top of a mountain in East Timor when Matt, a mate of mine, said something that’s stuck with me ever since. What did he say? “No one ever went broke making a profit” Why is that important? Because for eons, people’s innate aversion to pay the taxman has led to a string of poor financial decisions, which have been slowly bleeding them dry. One of those poor decisions (not in every case of course) is interest only loans. 10 years ago interest only loans made a lot of sense. The interest rates on interest-only loans were basically on par with principal and interest loans. It made perfect sense to go down that path to free up cash flow and maximise the tax-deductible portion of outgoings (the interest part of your home loan repayment). Today, the story is very different. Price pressures from industry regulators have increased the costs of interest-only loans so much that for most property investors, choosing an interest-only loan could be costing them thousands. The problem with this is, hardly anyone has changed their tune in terms of the type of loans they recommend to investors. Why? Well, they’re either lazy, they haven’t figured it out yet (pretty much the same as lazy) or they don’t have the smarts to articulate the risk vs reward. So to bust this lazy myth wide open we’ve developed a new calculator.

How can it help you?

This calculator will help you work out which loan type provides you the most benefit. We calculate the results by taking into consideration:

  • The interest cost of the investment loan compared to the tax savings of negative gearing
  • The amount you’ll be owing compared to your repayments

What do your results mean?

If your result is a positive figure (green coloured), you could be better off choosing a principal and interest loan. If your result is negative, you could be better off choosing an interest-only loan. Transparency is the cornerstone of everything we do at UNO. It’s why we get out of bed everyday. We couldn’t care less if you choose an interest only loan or a principal and interest loan. What we care deeply about is that it’s the right loan, for your specific situation, right now. To find out what works for you, use the calculator right here: And if you want to take it one step further than the calculator, you can book a call with our customer care team today.

Due to complications arising from processes and forms required by the lender, what should have been a simple process became super complicated. UNO Home Loans dealt with everything with calm and serenity and professionalism.

Paul and the team at UNO Home Loans have been absolutely amazing, helpful and transparent during the process of purchasing our home. This team has made buying a house an absolute breeze. It has been a 9 year goal for my family and I to get back into the market and from the first zoom call with Paul all the way to settlement I have felt taken care of and at ease. I am so excited to be in our own home and am very grateful for how easy UNO made the experience. UNO offered great communication, clear instructions and got the job done. Thank you Paul and the UNO team. I will definitely be using these services again.

Working with Scott Wilkinson at UNO Home Loans was a genuine pleasure. We used Scott to refinance our home loan and to structure an investment property loan. Both experiences were excellent from start to finish. Scott provided high quality advice, quick turnaround times and sharp pricing outcomes. Nothing was too much trouble. I look forward to using Scott’s services again and highly recommend to others.

Scott and the entire team at UNO has been skilfully in helping and assisted with my complex property financing structure in a such short time frame to execute my first investment property. He has engineered a powerful strategy to accelerate my investment property purchase while ‘Optimising’ my financial position efficiently. I couldn’t be happier with experience. They made the whole process smooth and willing to go extra mile to get me best deal possible. I highly recommend him to anyone looking for reliable and professional broker.

If only we could leave 10 stars... We've worked with Scott Wilkinson from Uno on the purchase of our principal place of residence, as well as a recently completed investment property. Scott was excellent throughout the entire process. He's got great communication, works incredibly hard and did everything he could to negotiate us the best deal. As business owners, the investment property was particularly complex and tricky to navigate. Scott helped us from start to finish and ensured we could maximise our borrowing capacity as well as secure a competitive rate. We've got nothing but amazing things to say about the guy and would highly recommend him to anyone considering buying property.

I honestly couldn’t recommend Paul Davey from Uno enough. He went above and beyond to get my pre-approval sorted, even with my tricky circumstances. He guided me through the whole process right through to settlement day and made everything so easy and stress-free. If you need a mortgage broker who actually cares and knows their stuff, he’s the one to call! Epic Service!
