They can start and then stop projects overnight.
Buying a property just because casino is being built means nothing really.
Apparently RAK is building something and the Dubai is just starting to build a casino (again) and it may take them a couple years to build (new artificial island with hotels, roads and everything).
So, let's say RAK opens up the casino first.
What happens when in 2 years after that once the casino is open in Dubai.
Who in the world will go to RAK then (maybe some people will but majority wont!).
How much would your property be worth then.
Also, people that go do Casinos, do they sleep in AirBnB style apartments or hotel rooms/suites?
