Wonderful experience!

Wonderful experience!

Working with Marguerite made the whole process extremely smooth and enjoyable. She was in communication with me every step of the way and if I needed anything I could text, email or call and she would have an answer as soon as she got it (if she needed to reach out to the sellers agent).

Complex sale goes smoothly

Complex sale goes smoothly

My family was selling an old, generational home with severe damage. The MaryBeth Tribbitt Group worked diligently to take care of everything. They were straightforward in their communication and detailed when explaining the process and answering questions. I was living in another state during the sale and had complete confidence that everything was being taken care of. I never had to drop everything and come deal with a problem in person, which as a busy parent was a huge relief. Very thankful for all the hard work the team did to ensure things went smoothly.

Patience of a Saint

I can’t say enough about the patience and guidance of Marguerite. She was thoughtful throughout the entire process and kept me level headed during an extremely emotional transition. Couldn’t have done it without her. We made a great team, but I never want her job. LOL Thank you!

We were only sent listings that matched our criteria, so time was not wasted.

MaryBeth stayed in regular communication with us during the whole buying process. She often adjusted her schedule to accomodate us because we lived out of town. MaryBeth always greeted us with a smile and was committed to helping us find the right place to call home.
