If you want an honest opinion , i went on a tour last week to ajamn , umm alqaiween, and RAK
I for sure would not put a penny in either three. the roads are a mess , there is no infrastructure , you feel like you are in the 18th century . and honestly if I get a house for free to live in it , i wouldn't .
so at the end of the day , remember location, location, location .
I don't think that the big Shaikhs in all three cities have the vision and the money to do what Dubai did in such a fast pace , it will never materialize and these buildings will be empty for a long time .
