Salaries are linked to experience, skills and nationality.

If you feel the salary offered is a good jump from what you are earning now, you should seriously consider it.

A decent 2BHK apartment would cost you QR 6k to 8k; car and fuel about 2k; utilities are quite cheap (max 800 for W/E/Internet); food depends on the size of the family, how often you eat out etc.

Of course there are the other expenses related to lifestyle.

Trust this helps.
