All but 4 of the US Cities listed are in Florida. Manhattan/NYC, Phoenix, Honolulu & Las Vegas made the cut. Florida real estate rivals Las Vegas for foreclosures, which from an investment point of view makes those hardest hit to have the highest ROI. Where are the buyers coming from? The majority influx is from the Far East, Russia and China. The international buyers have CASH and lots of it. Whether one mega mansion or an entire track of homes, the bet is on the US to repair its markets and economy. Unlike stock, real estate you can really enjoy while you own it. So why buy 100 small homes, when you could have one huge one?
