Hi jneel.
To be perfectly honest without housing I think you would be struggling. Housing would take up a massive chunk of that your salary (it works out at about QR21,000 per month).
I will be surprised if your company are not offering housing if they are aware of what is happening to rents in Qatar.
Schooling is also expensive.
It is normal for all international companies to provide exceptional pay and allowances (housing, schooling, transport etc) to their secondees
