If u said 14000 QAR including Accomadation + travel and all,it means ok..but if it is 14000 in hand,acc+travel separate,then it is a good offer..in fact very good..depending on the job profile and your years of experience.

For family accomodation,since it is expensive, you will need almost 3500QAR minimum as per single acco contract for Family visa requirement.

Family expenses should come to around 2500 riyals,but 10,000 riyals is minimum salary requirement for family visa.
