Mark Zuckerberg owns over 1,200 acres of land. Here's a look at the Facebook founder's US properties, from a Hawaii bunker to Lake Tahoe houses.

Over the years, he’s bought and sold homes all over the country. He’s also reportedly built some — a Hawaiian doomsday ranch that has had many scratching their heads, for example.

Zuckerberg’s real estate portfolio has an assessed value of around $200 million, according to Business Insider calculations based on property assessments.

However, the assessed value of properties can be lower than reported purchase prices (or current market value), so Zuckerberg’s holdings are likely worth significantly more.
