Wayne Gretzky – $13.5 million, California
Gretsky even managed to buy back a house he once owned for less than he sold it for. The property in question is a 13,200-square-foot mansion on the Sherwood Country Club he once sold for $18,5 million. After selling another house in Westlake village at a $600K profit, Gretzky bought back the Sherwood property for… $13.5 million.
