Further Lane de Menil, East Hampton, N.Y.
When you have neighbors like Jerry Seinfeld, you know that it’s going to be a pretty good area to live in. Financial genius Ron Baron apparently purchased 50 acres of undeveloped land in the posh community of the Hamptons for $103 million back in 2007. That’s just the land! He bought it with plans to build this spectacular dream house for an undisclosed amount.
