Housing is the major expenditure. Make sure you are offered a decent independent housing (if with family). Otherwise, atleast 6000-8000QR permonth for rent in housing allowance. Make sure the cost of schooling for kids is covered as well.
7000 riyal is just INR 120000. If you can make even 50% of that money in India you are better there. Otherwise, a salary that covers housing and kid's education could be considered.
