Mary Bay

Your Local Real Estate Expert

Trusted -- Knowledgeable -- Responsive

Buying and selling a home is a difficult decision, especially if you don’t have an experienced real estate agent to guide you through the process. As one of the top-selling realtors at Coldwell Banker Gundaker, we are a trusted team with knowledge of local market conditions and responsive quickly to our client's needs.

As a professional, full-time Realtor, I have dedicated my career to working with families in the difficult process of moving.  My own experience of several big family moves in a short period of time has given me empathy for the challenges involved in buying/selling a home as well as corporate relocations.  My goal is to help each family go through this process with ease, and get the highest price possible for your home in the shortest amount of time!  

The Bay Team is consistently praised by our clients for providing superior, unmatched service!  We enjoy building relationships with each homeowner with whom we work and doing all we can to make the home selling and buying process easier.  We remain involved with you throughout the entire process—giving you the tools to price and ready your home for a sale, meeting contractors and appraisers, setting up inspections, negotiating through the inspection process, holding open houses, etc.  To us, superior unmatched service is not just a slogan:  we do what needs to be done to get a home SOLD and CLOSED!
