Customer Reviews

Excellant service and communication. Very professional and patient in the process and explained very well through the challenges that came up during the process. I would gladly recommend Shelly to be your realtor.

Vernon Cain, St Joseph, Michigan | Home Seller

Shelly was an excellent agent, she understood my unique needs for my company and where we stood. We sold a difficult property and I couldn't be happier with her results. I will add, I will never take a buyer being represented by the same firm. Cressey & Everett's managing broker ignored my calls, and I did not feel like I was being taken care of as a client when the management was involved. I will reiterate, Shelly Horstmann is excellent. She was on top of all timelines and updates. We had a unique and difficult situation through closing and she handled it perfectly. I wish I could say the same for her management.

Shelly Horstmann was very helpful. If she didn't know the answer to something, she was quick to find it. She was always available any day or any time to answer questions. She was professional and approachable/easy to talk to. We were very satisfied with our experience with Shelly and will recommend her to all our friends and family.

Very helpful and persistent in locating vacant land in Cass county. Once located, negotiating and closing went very well. I would recommend her to friends.
