30. WILL SMITH – $42 MILLION, CALIFORNIA
When you are an actor, musician, and producer, and highly accomplished in all those fields, it’s only natural to assume that you don’t need a bank loan when buying a $20-million mansion. The Fresh Prince of Bel-Air did some significant upgrades and decoration which pulled up the value of his family home to $42 million, according to some sources.
This massive house, which is apparently in the market, is located in Calabasas. It features basketball and tennis courts, a golf course, meditation lounge, and even a recording studio.
