Mark Zuckerberg spent almost $60 million on 2 waterfront estates in Tahoe. He own 10 properties across the US, from a modest Palo Alto home to a Hawaiian plantation.
He has properties in Palo Alto, California; San Francisco; Lake Tahoe; and Kauai Island, Hawaii.

So I definitely wonder what is simple means for you.
