This house, or more precisely, three houses in one, is the most expensive property to be on sale in the state of New Hampshire. It belongs to the family of Bob Bahre, a founder of the New Hampshire International Speedway who sold their stake for $340 million. Their property sits on 66 hectares on the shores of Lake Winnipesaukee. There are two houses, one belongs to Bob and his wife Sandy, and another one to their son Gary. Two houses total about 6,000 square meters (63,000 square feet). There is also a barn where the family hosted NASCAR drivers before their races.
