Sale price: $6,825,000 Seller: Steven G. Cates Seller’s and Buyer’s agent: Steve Fridrich, Fridrich & Clark The buyer of this Belle Meade mansion hid behind an anonymous trust and we can’t really blame them. This is a heck of a purchase. The massive 9,300-square-footer sits on 1.2 acres, but who needs a yard when the house is equipped with five bedrooms, four bonus rooms, three fireplaces, two kitchens and an in-ground pool next to a spacious covered porch? It’s got geothermal heating and cooling, central vacuum and smart irrigation, cameras and lights, too. What else does it do, clean its own kitchen?
