And you thought your local housing market was expensive. ABC News offers some perspective with their slideshow of the 33 most expensive homes in the world. I would have thought the most expensive home would be Bill Gates's, but it's not even close. The number one slot belongs to the 20-acre estate on the French Riviera that recently sold for $740 million. Whoa! Angelina Jolie and Brad Pitt's home isn't too bad either. Although I like the home with the 12-car garage. That will come in handy when I pick up another 11 vehicles. The rich lead much different lives than you and I.
