"We recently got our refinance done with Jeff from Interstate mortgage. That was an outstanding service that he provided and a great transaction! Not only we locked in the lowest rate possible with him, he was super responsive! Like others said, even if you send him an email at odd hours, you'd get his response in minutes. He understood all our concerns and also responded to our questions well and quickly. On top of the great response time, he was thorough and would let us know what obstacles might be before submitting everything so we were well-prepared. Working with him, you'd feel that not only he's working to get this done, but he really cared about the services he provided and our business. What a nice guy and what a wonderful experience to work with Jeff. We highly recommend him if you're looking for a fantastic loan application process, he's the guy to go to and you'll never regret it."
Thank you, Jeff!! =)
"Jeff from Interstate Mortgage really did a stellar job as my advocate, and pushed through some sticky issues on behalf of my refinance over the course of multiple applications to multiple lenders. His responsiveness and follow-through were absolutely better than I would have expected and he found me the loan and terms I was looking for - which another highly rated Zillow-sourced broker had not been able to secure. I also particularly appreciated Jeff's clarity, patience, urgency and capability to resolve complex issues/questions via communications by phone, email, and txt, as I can be difficult to reach. All in all I couldn't have asked for more."
