Great chart. Yeah, the information looks accurate. Florida has ALWAYS been really popular for foreigners. Especially all the Latin American community from Central and South America. Almost all of my more affluent friends in South America all own something in Florida. And notice the high percentage that pay with cash. Cash is the norm in many cities in Latin America.
Of course LOTS of them got burned buying during the bubble in Florida. But all of the ones I know paid cash for their properties in Florida and still are hanging on to them.
