hiya,

I think i'll put forth some of my experience since i've recently moved into qatar in similar terms as you are.

for me its me and my wife only.

But from my experience you might be incurring the expenses as follows

A. rent : 6500 (Two bedroom; fully furnished)
B. Car : 2000 ( Nissan TIIDA type)
C. Petrol : 200 (80 dhs/litre)
D. Provision : 1800
E. Electricity & water : 250
F. Internet : 200
G. Telephone : 200
TOTAL 11,150

Thats it . these are the compulsory expenses. with the rest of your pay you can either save or doha is a great place for shopping and eating out. Items A&B can vary as per your taste and choice.

If you need to be still in a posh atmosphere and drive around a posh car then this will drastically vary.

There are certain initial expenses which you need to be very careful about.

for renting out houses the agents can ask one month rent as commision and one month rent as advance.
If you are new to GCC then taking a license will be a little bit expensive. probably about 4000QAR.
I hope all the visa expenses and tickets to hoem town and medical for family and self is included in the package.
