Ayman,

In my opinion it very easy to buy (property, house, anything) in countries where you're allowed, but it is a LOT harder to sell... all the odds are against you when you are a foreigner, anywhere in the world, even in the States when you are not a citizen. The legal paperwork, the fees for lawyers, agents, withheld taxes (may be not for Qatar), duties and all the rest are overwhelming, not counting the time it takes to get your money out and run.

In my book, when you're not living in your home country : just rent, do not buy, unless you have money to burn + you really know what you're doing and you're connected with the right people.

In other words, you have to master the procedure to sell, before you get into buying.
