Tennis might not be as popular a sport as basketball or football, but those on top of the rankings are making money like you wouldn’t believe. They need it too, considering the houses and cars these people own. Even paying for their car insurance could lead them to bankruptcy if their bank account doesn’t get regular injections of cash, and don’t even get us started on the home insurance costs of their mansions! Some live so lavishly that tournament prize money alone couldn’t cut it. But if we consider their endorsement deals, the money they get for commercials and sponsorships, it becomes easier to understand why they’re not trying to get a mortgage on their house. Without further ado, here are the cribs and the wheels of the richest stars in the tennis world!

Novak Djokovic – Miami, Estimated $15 Million

One of the best players to grace tennis courts, Novak Djokovic holds a total of 68 titles and has won over $100 million in prize money during his career – which still isn’t over. A smart cookie, Novak started making investments as soon as he could afford to, so he didn’t just dump all of his earnings into a savings account and called it a day. One of his latest moves was in real estate, purchasing a luxury home in Miami Beach, worth an estimated $15 million. The 4,140-square-feet condo has five bedrooms, a gym, outside bar, spa, private garden, terrace, and of course, a pool. It’s not yet clear if he’ll move there from Monaco or if he just wanted to add this property to his collection.
