First listed in October 2010 for $3,450,000, this Centerville waterfront listing has remained at the same asking price since. Over a year and a half later, it looks to have found a buyer. Now that's what we call sticktoitiveness. The two and a half acre property sits on Nantucket Sound with a private sandy beach. The 4648 sq. ft. (with floorplan porn!) seven bedroom, five and a half bath, built in 1910, has "panoramic ocean views." Amenities include a sauna, outdoor shower, carriage house and association tennis. Anyone care to venture a guess as to the final purchase price for this "Classic Cape Cod waterfront property"?
