I think this is a pretty poor offer. 44,000 pounds per year seems low for an MD (88K usd) The housing is low as well. If you're looking to live a simple lifestyle in a muslim country it might be okay but I don't think you'll be able to save much over the long run.

I don't know what the salary for a GP here is, but I know that faculty at the medical college are are closer to the 55 - 75 thousand pounds at least, plus a much better transportation and housing allowance.
