A $16.8 million Silicon Valley mansion in the Palo Alto neighborhood where Facebook CEO Mark Zuckerberg lives hasn't found a buyer in 6 years — take a look inside

The three-story Italianate-style villa at 51 Crescent Drive sits in Palo Alto's Crescent Park district, where Facebook CEO Mark Zuckerberg owns a 5,000-square-foot home that he bought for $7 million in 2011. The $16.8 million villa has lush gardens, a pool, a hot tub, and beautiful bay windows on a half-acre of land. It landed on the market in April 2019, but it's not the first time it's done so. In fact, it's been on and off the market since 2013 and has yet to find a buyer. But Coldwell Banker realtor Joel Goodrich told Business Insider that this is what's called a discretionary sale. The owners don't have to sell just yet, Goodrich said, so they're waiting for the right timing and the right buyer to take them up on their $16.9 million price tag, well above Crescent Park's median real-estate value of $4.5 million.
