Muhammad Ali – $2.5 Million, Michigan

American professional boxer, philanthropist, and activist Muhammad Ali began his professional career at the age of 18 and was at the top of his career until his retirement in 1981. He was famous for bragging in the ring, his criticism of the government, and his adopted religion.

Ali’s Michigan property had a pool, two barns, an outdoor kitchen, a massage room, a steam room, a gym, and a boxing ring. The house belonged to him for over 40 years and was sold by his widow, Lonnie Ali, after his passing in 2016.
