Why are they buying? Only 39% of Chinese buyers said they intended to use their purchases as their main home.
Some may buy condos for their children attending U.S. colleges. They hope that, in addition to saving on dormitory fees, they can make benefit from home price appreciation by the time the students graduate.
Others are becoming landlords, buying cheap homes in distressed economic pockets, like Detroit, and renting them out.
Still others use the homes as vacation properties a couple of weeks a year and rent them out the rest of the time.
In addition to the tide of Chinese buyers and the Canadians, those from Mexico, India and the United Kingdom filled out the top five list. India also had a notable jump in money spent -- 48% growth.
