Frequently asked questions
Our interest only mortgage repayment calculator is a simple and convenient tool that lets you see how much you will pay on your loan. All you need to do is enter the details of your loan, such as the amount, the interest rate, the term, any fees, the interest only period, and the repayment frequency.
The calculator will then show you a chart with your projected repayment timeline and a summary with the total interest and principal you will pay.
The length of the interest only period depends on your personal and professional circumstances, goals, and preferences. There is no one-size-fits-all answer for this question. That’s why we have a team of professional DPM loan brokers who can help you find the right loan option for you. They can help you compare different interest only periods and see how they affect your repayments, interest payments, and tax deductions. If you want to get personalised advice on your interest only period, we recommend booking a free consultation with our lending specialists today.
An interest only loan is a type of loan where you only pay the interest on the principal amount for a certain period of time. This means that your repayments are lower during the interest only period, which can help you manage your cash flow and budget better.
An interest only loan can also be beneficial for certain tax purposes, as you can deduct the interest payments from your taxable income. However, an interest only loan also has some drawbacks, such as higher interest rates, higher total interest payments, and lower equity in your property. An interest only loan may not be suitable for everyone, and it requires careful planning and consideration. That’s why we recommend speaking with a specialised loan broker to determine whether an interest only loan is right for you.

Our client reviews
We’re proud of our expertise delivering financial services for doctors, and so are our clients.
I would like to share my appreciation for the exceptional service provided by Danha and Dino during our recent home purchase.Danha's work as our financial broker was outstanding. She understood our need and financial situation very well. The way she managed the homeloan process—getting us pre-approval results quickly and accurately in a short period—was invaluable. It gave us the confidence to bid decisively and ultimately secure a home at a great price.And a huge thank you to Dino my Accountant for his assistance in preparing all the necessary documentation. He has been looking after all my accounting matters thoroughly and wisely over the last 15 years. His help streamlined the process very well again.Thank you both for your dedicated and highly effective support.

Julie Anderson at DPM has been my accountant for years now - and i couldn't be happier, or more satisfied with the professionalism, advice and care, she has shown me. And a big 'thank you' also to Danielle Davis, who has always been most helpful and efficient whenever i have any requests, or need help. Her courtesy and warmth are most greatly appreciated...

The service from Naomi Li (mortgage broker) was excellent. Her communication was clear, timely and consistent throughout the entire process. She was always available and easy to reach, which gave me great peace of mind during my new house settlement period. Thanks to her professionalism, attention to detail and genuine care, my settlement went smoothly from start to finish. I wouldn’t hesitate to use her service through DPM again.

My partner and I cannot speak highly enough of Kimsor - he has been absolutely wonderful, incredibly responsive and reassuring, and is solely responsible for giving us the confidence we needed to secure our first home when we had uncertainty with the bank due to complexities with assessing salary as a medico. We reached out to Kimsor as a Hail Mary on an emergency basis with no prior contact right when we were losing hope to secure our pre-approval before the house we loved was due to sell, and it has been smooth sailing ever since with his clear explanations, receptiveness to our needs and aspirations, responsiveness and expertise in the area. What had begun as a very arduous and complex process with the bank was immediately simplified for us with Kimsor's help and we could not be more grateful for his time, compassion and diligence in assisting us with our purchase. Thank you, Kimsor!

We are new clients of Dino and Jamie on the recommendation of friends, having changed from another medical accounting firm. We have been so grateful to them and the team at DPM for absolutely wonderful service and care in our first year of being their clients. They have really stood out with all the expertise and attention to detail you would hope for, in addition to the kindness and excellence in communication skills that you didn’t know you needed from your accountants. We couldn’t recommend them any more highly.

One of DPM's lending consultants Marissa Tzivakis helped me find a loan recently. I'm so very grateful for the work she did. She listened, understood the challenges (and the stress), came up with some great options in lightning quick time, and followed me through until it was sorted out. I really can't recommend her highly enough - not to mention the work of financial advisor Michael Blood and his team who've been looking after me for more than 15 years, and turned up exactly when I needed them

Ali Baker

Danha Ngo is an outstanding lending consultant who went above and beyond when helping me purchase my first home! I was very hesitant at first to get a lending consultant but Danha was very knowledgable and able to get me the best variable rate on my home loan within such a short period of time. She was very honest, and educated me on reviewing all documents and walking me step by step through the entire process even though I asked 100's of questions. Responded very promptly to emails and phone calls, making my first home purchase very easy and hassle free. If you're looking for an expert in her field who knows how to navigate her way around home loans to get you the best deals and to expedite loans, then I cannot recommend her enough and will be using her again in the future. 10/10 service!

William Indrawan and his team were very extremely helpful in helping me with my taxes - they were professional, efficient and very knowledgeable. It would have taken me so much time and dedicated research to find out what deductions you are allowed for your taxes as a medical doctor, especially coming from another country. The service was very personalized and such a pleasant personal interaction. And yes, I had a good tax return! Thank you!

I have been a client of DPM for almost 2 years now, and they are a fantastic team that really do give you bang for your buck!My acountant has helped me navigate through the complex world of salary packaging, and has been excellent in completing tax returns each year. He doesn't just "do my taxes," he explains things and helps me understand concepts myself so as to calm the stress levels. When I wanted to apply for a home loan I was directed to a Lending Consultant who has been nothing short of brilliant. They are efficient, they are helpful and they are extremely approachable. I don't know how much money I would have wasted had I not had DPM's guidance. Definitely worth it!
