hi, to be frank with you salary is bit low compared to the living cost in Qatar, it is too expensive over here, a moderate single bedroom decent house will cost you not less than 3500QR ( Ezdan wakra), kids education will cost you not less than 500QR per month, a small vehicle ( which is essential) will cost you a EMI of 700QR / month( for 5 years), normal grocery for 4 will cost you around 2000 ( very minimum), so you will end up borderline without any savings, think judge and decide.
