According to Palm Beach powerhouse and real estate insider, Jeff Lichtenstein, Venus and Serena Williams never have to leave their home again. The sisters have added an enormous fitness center and double tennis courts to their jaw-droppingly beautiful BallenIsles property in Florida. Purchased a decade ago, the V-shaped home allows each sister to have her own master suite, which is more like their own master-mansion.
In the past, they've played tennis like civilians at local courts, but that's all about to change. Beyond the triple-guarded gates, they'll share the multi-million-dollar training center and tennis courts with each other and a lucky few. With more than enough to go around, sibling rivalry will not be an issue. Lichtenstein has more BallenIsles properties here, in case you're looking to move in and play doubles.
