Bill Gates – XANADU, $154 Million

Bill Gates is known for being the co-founder of the trillion-dollar company Microsoft, and for being a fierce rival of another iconic entrepreneur Steve Jobs. He has consistently been among the top 10 richest men in the world for a few decades now that it’s hard to imagine him running out of money in his or his children’s lifetime. Indeed, with a net worth of over $100 billion, what else can he not afford?

His main residence has taken a life of its own as it has already become popular for its smart-home capabilities. We can expect that it also comes with a high-tech home security system. The 66,000-square-feet real estate was only worth $2 million when he bought it in 1988. Now, the stunning mansion is now worth an amazing $154 million! The high-tech abode boasts seven bedrooms, 24 bathrooms, and has ten baths. As billionaires, this is just what we expect from Mark’s and Bill’s multi-million properties!
