Testimonials
" When it comes to buying or refinancing real estate, time is of the essence. In all of my years in real estate, I have never been more satisfied than I was with the prompt and thorough service that Michael and Susan provided - prompt because they eliminated unnecessary delays; thorough because they helped me to see the larger picture before focusing in on my financing options. They guided my loan through the wilderness of tight credit, finding the best rate and most flexible financing available, and I was kept informed of their progress every step of the way. We closed without a hitch, which is remarkable these days. If you need a loan, I don't think you can find better, more competent people."
Stacy Greenspan
"We recently refinanced our house in Denver. We have bought and sold a number of properties, and done other refinancing, but never before have we worked with such competent and capable people. Everyone we worked with was friendly and very knowledgeable, not just about our loan but about helping us find the product and rate right for us. From the minute we called for advice, through the application process, until the closing, we were so impressed with their skill and breadth of knowledge with all aspects of obtaining a mortgage. They were able to process our application very quickly, which allowed us to be positioned to move when appropriate. They kept us updated regularly with the rates, and helped us decide when the best time was to lock in. Not only are they wonderful to work with, we were so impressed with everyone they are associated with, from the appraiser, to the gentleman that came to our house for the closing on a Saturday morning(our choice), to the underwriter of our loan. If you choose to work with Interstate Mortgage Service, you are truly in the best of hands. "
