The late boxer Muhammad Ali once lived in this mansion in Berrien Springs, located about 170 miles from Detroit on the southwest side of the state, now available for sale for a cool $2,895,037. The 3,960-square-foot property has three beds, two baths, and sits on a 81-acre property. The property was updated by Ali in 1975, and includes a full-size boxing ring (naturally), a private gym, a steam room, outdoor pool, and a guest house. Ali died in 2016.
