Salary looks good. Definitely this offer may not from a private clinics so all the best. :-) :-) I know where you will work.

Being an 8 yrs experience doctor, hope your childs are not in higher education so that is not a problem to relocate here.
Your expenses will not be more than 5k in Qatar since accommodation, child education, (anyway medical too ) and annual flight is taken care already which are the worst part of loosing our savings here.

All the best.
