Seller reviewBill is very knowledgable about the condominium association located at 320 Blue Star as well as our community. This knowledge is very important when dealing with buyers in a second home market.
-
Seller reviewBill is an absolute pro. He takes care of every detail and communicates effectively during the entire process. I would encourage anyone looking to buy or sell in the area to work with him and only him. I live out of state and Bill made this sale as easy as pie!
-
Seller reviewBill Underdown was great to work with. He went beyond the house sale to help us in many ways, and he helped make the house sellable in our absence. Thank you.

Buyer reviewAwesome realtor to work with
-
Seller reviewBill was a personable, efficient, and hard-working realtor that did an awesome job.
-
Buyer reviewBill made the bridge between buyer and seller a firm but agreeable lo e final outcome. Both parties want their needs to be satisfied, and in the end an equitable agreement can make the whole transition beneficial and smooth for both parties. He was a consummate professional who looked out for us and made the transaction smooth for all.
