Buyer reviewI have worked with numerous real estate professionals through the years, both residential and commercial. I can say with confidence that Bill Underdown is the best realtor that I have ever worked with. He knows his market, knows his customers and is creative in solving problems and closing deals, all while fostering relationships that transcend real estate. I would now consider him a friend.
