Looks like Serena and Venus Williams are about to win a point in the real-estate court. The sister tennis stars bought a Palm Beach Gardens property together back in 1998 for $525,000. After building a gorgeous mansion on the land, the sisters are finally listing the spot for almost four times the original price at $2.69 million, according to Variety.

With Serena owning two other mansions in town, it made sense that the grand slam winners could give up this amazing pad. Located on one acre, the home is complete with two separate wings, perfect for giving each sister some personal space when residing at the property together.

Complete with a well-equipped gym for training, a gorgeous pool, and even a home movie theater, this home was designed to fit every need of these superstar athletes. Want to take a full tour? Read ahead to explore the champions' mansion.
