The house, which was built in the 1980s, has fallen into disrepair over the years.

Serena and Venus Williams lived there with their father, Richard, who helped them learn the game of tennis as they grew older. Their journey was chronicled in the movie King Richard, and they went on to become two of the greatest players in tennis history.

Venus and Serena moved to the house as teenagers after Richard purchased the property, which features two tennis courts on its 10+ acre lot. It's pretty cool. It's the court where "King Richard" trained his daughters.

Their childhood home also had the memories before they became two of the greatest tennis players and athletes that the world has ever seen.

According to the notice of sale, the house will go to "the highest and best bidder for cash.”

According to Vogue, Serena Williams has been the focus of the tennis world of late in August that she was "evolving away from tennis, toward other things that are important to me."

However, she pointed to Tom Brady's decision to retire and then unretire during an appearance on Good Morning America and suggested her tennis career may not be done.

"I mean, you never know," she said (h/t ESPN ). "I've just been saying that I think Tom Brady started a really cool trend."

The home where a 23-time Grand Slam champion honed her game before she became one of the most famous tennis players in history is expected to sell for an impressive sum.
