The salary doesnt seem to be that attractive.. The house rent in Qatar cannot be compared with Bahrain.. My brother is in Bahrain and is paying for a villa which is only 300 BD.. Here you wont get even a 1 BR flat for that rate.. So think before you take a decision..

As you have a small family.. u can manage to get a single bedroom flat for 4000 QR... Electrcity + water will be around 200 QR... Expenses around 3500 QR (depends on your req..).. You can save 4000 QR..

But as you are in QCHEM, which office you will be placed ? is it ras laffan or messaied.. If it is there.. u will get houses even cheaper...

So think..and take a decision carefully..
