From the couple’s website: “At Intermandeco, specializing in residential land development means more than selling lots to homebuilders. It also means establishing quality communities with long-term appeal—places that make people look forward to going home.” When they go home, it’s to a 12,984-square-foot Italian villa on Strait Lane. Why did they fall 19 spots? Every year since 2008, they’ve managed to get the value of their house reduced.
