I do not understand why anyone would want to buy property anywhere in the GCC if they are not a national of that country. The rules changed suddenly to allow it, the rules can change just as suddenly to remove it. Expats will have no legal recourse in such a case. Buy in your home country or buy in a country that does not allow this to possibly happen, or at least has a legal system that allows you to get some form of compensation or other legal redress.
