Buyer reviewBill was phenomenal to work with. He understood exactly what we were looking for and applied his local knowledge to our home search journey. He did not hesitate to tell us if a properly was not worth looking at. His communication via text and email was incredibly helpful and kept things moving along as we often cannot be on the phone.

Seller reviewBill is a good man and he knows his stuff. I have been trying to sell my property for some time now and Bill simply knew how. He has knowledge of the community, the presentation of the property was excellent. He is what was needed.
