It’s no secret that foreign investors are changing the real estate landscape in the U.S. right now, especially with respect to the luxury market. According to the National Association of Realtors, more than $82 billion worth of homes were sold to international buyers in the 12-month period ending in March 2012. Buyers from China and Hong Kong alone accounted for $9 billion in U.S. home sales during that same time period, and that doesn’t even consider the large number of private sales transactions not officially reported.
