Buyer reviewI was at an event where someone recommended him to me. Bill Underdown and I met. We immediately scheduled a time to look at properties. Things fell right in place. I did some research and made an offer. Bill was very helpful and attentive from the beginning to closing.
-
Seller reviewPositive Attitude, Honesty, Work Ethic, Trustworthy, Compatibility. I would rate Bill a 10 in all of the above! One Word describes Bill, EXCELLANT! I have the utmost respect & highest opinion of Bill Underdown. I highly recommend Bill. You will not be disappointed. My experience dealing with Bill was by far the best I've ever had with a real estate broker. I didn't have to worry about anything. Bill was with me 100% on this journey. I had complete trust in Bill which is so very important when selling an upscale property. If I ever need a realtor in the future, Bill is my guy. He is thoughtful, thorough, & a delight to work with. In my eyes, Bill is the absolute BEST & outshines all others.

Seller reviewThe sale of my home was interrupted by the pandemic and took an extended time to sell. My realtor Bill Underdown always had a strategy to moves things along and listened to the strategies I suggested.

Seller reviewThank you for selling my house

Buyer reviewI am from out of state and needed someone with local knowledge that I could trust. I asked 2 friends who they would recommend and both said Bill Underdown. As I purchased a lot there was a lot for me to learn, no pun intended. Bill was able to connect me with Banks, Builders and Architects. We just closed on the property and hopefully I will be building in a year or so. I have assembled a great team with Bill's help and can't wait to get started and become a Douglas Resident.

Buyer reviewNot being familiar with the Douglas/Saugatuck area (other than vacation visits) Bill was great to deal with because he was not only knowledgeable about local real estate but about the area as well. He has been a very valuable resource as I get to know the area better.
