I think after paying accommodation, schooling, utilities, car, etc, you would be left with very little money to pay for school activities, school bus, uniforms, dentist for example. Are you only going to have 1 car? how will your wife move around? If it's 2 cars you need, you're probably looking at 4K at least.

Obviously it depends on what your current lifestyle is and questions such as, does your wife currently work, are you giving up another salary there? is she planning on working in Dubai? do you intent to move so you can save or just to see the world an experience a new culture?

You're the only one who can make a decision, but I think 10K for every day expenses including utilities (if you're in a villa electricity and water can cost you 2500 AED!) seems a bit tight to me, considering you're a family of 4.

I'd suggest you try to negotiate the schooling and the living allowances to make them higher.

Good luck
