In a world with predatory practices everywhere, Jeff was honest, open and extremely transparent - no word salads, no difficult nomenclature without an explanation attached to it, no con games, no secret upselling. He was very generous with his time, including the very first call we had. The most helpful aspect was his communicativeness. I was able to reach out without a barrier when I needed to clarify a crucial detail - via a text, an email or sometimes a call, both while house hunting and after going under contract. The information I got set my expectations right and helped me make better and well-informed choices while I was interfacing with other people like realtors and insurance agents. Financing, which is usually the most difficult part of a home purchase process, was the easiest part for me due to Jeff’s help. Thanks again.

Jeff was very professional and helpful from beginning to end. He is clearly quite knowledgeable with home loan/mortgage options and proceedures. Jeff was also available to answer any questions from me or my client as they arose. Everything went smoothly. Very pleased!

Jeff was always available whenever I had questions. He kept me updated every step of the way. He explained things that I didn't understand. Never felt rushed or like I was an inconvenience. I would definitely recommend using Guild mortgage. I will always be using them in the future.
