Buyer reviewBill Underdown handled our transaction professionally while working to ensure that there were no issues with closing the transaction in a timely manner. He kept us up to speed on all aspects of the transaction which gave us peace of mind during the whole buying, selling and moving process. I would recommend Bill Underdown to anyone who is looking to buy or sell in the Saugatuck/Douglas Michigan area!

Buyer reviewBill Underdown genuinely cared about helping our family find a new home before we decided to build (in which he was very hands on with the purchase of our lot). Bill went on an extended adventure during our process of both selling our house and offering on a piece of land. Even while being in a different timezone, we were still able to reach Bill. Not only that, he left us in great hands with Erica Shirey to help facilitate the selling of our home. Both Erica and Bill made us feel like we could approach them and reach out with any questions. If they didn't have an answer, they got the answer for us and followed up. We were extremely satisfied with their communication! Bill went above and beyond our expectations. Not only did he work for us, but now we have a new life-long friend!

Seller review"From the very start, Bill Underdown had my best interests at heart. He proactively pursued price negotiations and a final sale to the utmost of his ability. And I will use Bill for any future sales or purchases."

Seller reviewFor a competent real estate broker Bill Underdown fits the bill. He was extremely helpful in Marketing and developing the land for sale. His expertise, competency and, experience was helpful in selling and listing our property for sale. I highly recommend Bill Underdown as a realestate agent to handle the sale and or purchase of any property , land and home. You just can,t go wrong with Mr. Bill Underdown.

Buyer reviewWithout hesitation I would recommend this broker. Bill Underdown managed to make the improbable the entirely possible. He changed the course of what had been an exceedingly difficult year and paved the way to a just short of perfect new living situation. (OK there is no gorgeous little lake that the deck looks over) He found that "Forever Home" and made it happen, especially with respect to finding creative solutions to financing. It's been a journey, but he always had his "eyes on the prize" for myself and my work as a practicing artist, art historian and art collector. It will even be ideal for my soon to be canary or two. Thank you.

Seller reviewTotally enjoyed working with Bill. He was professional and patient with all our question. Our condo sold in 36 hours for a fantastic price.
