#1 Shaquille O'Neal's mansion robbed him.
Back when Shaq was still playing ball for the Miami Heat, he was living in an $18.8 Million home on Star Beach. It was a 19,400 square-foot home with 8 bedrooms, a tennis court, a 6 car garage and then some. Once he put it up for sale, he (and he alone) thought it was worth $35 million. Nobody bought it and he ended up having to sell it to a realtor for $16 million putting him in the hold $2.8 million! Ouch.
