MICHAEL PHELPS – $4.125 MILLION, SCOTTSDALE

Michael Phelps, who is perhaps one of the most decorated Olympians of all time, bought this Scottsdale abode for $2.5 million in 2016 but reportedly listed it for $4.125 million. Phelps purchased the house after he became the assistant swim coach for Arizona State University. It’s not clear yet why he’s putting it up for sale, though it could be that he and his wife are searching for a much bigger Valley home.

If—or, when—the celebrated swimmer finds a buyer, he’ll be looking at making a pretty penny, considering he’s parting with the property for almost twice the amount he purchased it for. The mansion features five bedrooms, seven bathrooms, an enviable wine cellar, a more than adequately-sized pool (Phelps likes to swim, after all), four fireplaces, a sports room, and probably a home security system. The new owner will have a lot to be happy about in this investment property; not only is it exquisite, but its former owner also won 23 gold medals at the Olympics.
