This incredible mansion located in the Los Altos Hills belongs to Yuri Milner who might be either the smartest or luckiest investor on the planet. He had the wild idea of loaning money to an up and coming website that showed potential signs of success. That website was Facebook, and Milner made an absolute killing from that single investment. His Silicon Valley mansion is valued at well over $100 million.
