What customers say

Based on genuine customer reviews

Mortgage broking, refinancing and home lending form the core of the work at Osinski Finance, and the feedback from clients centres on how smoothly those processes are handled. Amy is named frequently, with customers describing her as patient and thorough as she explains each stage of a first home purchase or a refinance in plain terms. Nathan also features in accounts of finance applications, where reviewers note his quick responses and his work to resolve a pre-approval issue in time to meet a finance clause deadline. A theme running through the feedback is the clarity of communication before, during and after the loan is arranged, including answers to questions raised outside normal business hours.

Customers in several reviews describe the service as well organised and efficient, with timely updates that left them feeling informed and supported rather than left to chase progress. The firm's advice on refinancing and the patience shown to first home buyers, including those new to the Australian market, are recurring themes, along with the effort staff put into securing a competitive deal and simplifying the paperwork. Buyers and refinancers alike return to the team for subsequent loans, citing the consistency of the experience.

I’ve been using my Osinski Finance for the past 6 years and honestly wouldn’t go anywhere else. Every time I need finance, they somehow work their magic and make things happen! They consistently go above and beyond, and their customer service and communication are second to none. Nothing is ever too much trouble, and they’re always there to answer questions and keep you updated throughout the whole process. Highly recommend them to anyone looking for a finance broker who genuinely goes the extra mile. Thanks again Nathan and team for everything you’ve done for us over the years and continue to do!

I had a really positive experience with Osinski Finance, especially after having a previous bad experience with a mortgage broker. Nathan was easy to talk to, approachable and genuinely helpful throughout the process. He made everything feel much easier and less stressful. I really appreciated his professionalism and would definitely recommend Nathan and the team at Osinski Finance.

Amy and the team at Osinski have been absolutely amazing and we would 100% recommend them to anyone looking to secure a mortgage or refinance. We have recently moved from the UK, so this is our first mortgage process in Australia. Amy guided us through it seamlessly and secured us an amazing deal, as well as helping us understand every little part of the process and answering our hundreds of questions! We really cannot recommend Amy and the team enough, and now that we are set up with a beautiful home, we will certainly be customers for life. Everyone was so welcoming and helpful, and we were made to feel comfortable from our very first appointment. We couldn't be more grateful for everything Amy has done for us - Thank You!!

We would definitely recommend Osinski Finance. Nathan has been so insightful and patient with all our questions. He has taken the time to thoroughly understand our goals and personal situation while creating a pathway for us to buy our home, which would have been very difficult to do without him.
