My article on Tuesday may have gotten you thinking about putting your money to work somewhere harder in real estate. And that may, in turn, have gotten you lamenting the fact that you totally missed out on the Detroit recovery. Well, first of all, the Detroit recovery may not have been quite as solid as it’s been reported (sure, you can’t buy too many $500 houses any more, but median property values are still down 50% from 2006 peaks). But never mind Detroit. Detroit doesn’t have a beach. You need to be shopping in Puerto Rico.
