At just 34 years old, Facebook mogul Mark Zuckerberg is worth an estimated $66 billion—even after he lost $16 billion in a single day. The tech wunderkind has plenty of real estate holdings to fall back on. In fact, he owns a series of properties across the country, including 700 acres in Hawaii.

Let’s take a quick peek at the Mark Zuckerberg Real Estate portfolio. And yes, you can share this post on Facebook!

Palo Alto Paradise

After leaving the frat-like “Facebook House” behind, Zuckerberg purchased his first home in 2011. The Palo Alto home, located in the ritzy Crescent Park neighborhood, is over 5600 square feet. Originally built in 1903, the 5-bedroom house underwent extensive renovations while maintaining its original charm.

The home features a banquet-sized dining room, a saltwater pool and spa, and an outdoor entertainment pavilion. Sounds like a party!

There Goes the Neighborhood

For a man whose entire fortune is built on social networking, Zuckerberg prizes privacy above all else. He married Priscilla Chan in 2012, and the couple purchased a total of 4 properties neighboring their Palo Alto retreat. They originally planned to tear all of the homes down in order to expand their current compound, but city officials blocked the move.

Zuckerberg was also hit with a lawsuit when one of the sellers claimed Zuckerberg promised to introduce him to other high-profile people in the tech world as part of the offer on the house.

San Francisco Bound

Zuckerberg once again ruffled feathers with the neighbors when he purchased a home in San Francisco. The $10 million property apparently required extensive renovations that tore up sidewalks and blocked street parking for almost a year and a half. It also seems he overpaid for the home, since experts put similar properties in the $3 million range.

Hawaii Heaven

The Facebook founder wasn’t done yet. In 2014, Zuckerberg and Chan shelled out an impressive $100 million for a big chunk of Hawaii’s Kauai island. They planned to create a kind of plantation on the acreage, including a 6100 square foot home, an organic farm, and security and administration offices.

There was just one problem with Zuckerberg’s plan—locals owned small parcels of the total acreage, and they weren’t interested in selling. These small plots had been held by the same families for generations. When Zuckerberg levied lawsuits against 8 of the landholders to force them out, it backfired big time. He eventually dropped the suits and admitted that he’d made a mistake.
