Recently, we've taken a look at Bill Gates' insane Washington mansion Xanadu 2.0, and Mukesh Ambani's 27-story, 400,000 square foot skyscraper "Antilia". However, the world is full of very wealthy people with some pretty crazy-priced homes. Consider that the gym in Bill Gates house is bigger than most people's homes and costs more than an entire block of homes in your typical American suburb. That doesn't even come close to the reported $1 billion cost of Ambani's house. And those are just two of the many lavish homes of the world's billionaires. Below we've assembled a handful of some of the most luxurious estates. These are the types of properties where the taxes alone on the land are exponentially more than the median American income. However, we can dream, right?
