8. Randy Johnson
Big Unit, bigger house. Well known for his intimidating size (6-foot-10) it’s only fitting that Randy Johnson bought an equally massive house. The legendary lefty purchased an epic 25,000 square-foot home in Paradise Valley, a suburb where athletes including Muhammad Ali, Mike Tyson, Shaquille O’Neal, Charles Barkley, and Steve Nash have resided. When Johnson recently put the home on the market (he and his wife decided to downsize), the listing price was a whopping $25 million. That ridiculous sum of money will get you a home that has seven bedrooms, 12 bathrooms, a 2,000-square-foot workout room, a theater room with a snack bar, and a guest house big enough to accommodate an entire baseball team.
