Life is not that expensive in Sulemaniyah compared to Erbil or Baghdad for example. expenses depend on your life style but averagely with some $600 you can well live, considering that you do not pay alot for your rent.
There are many furnished and modern apartments in the city where expats can live, they are so comfortable too: Places like pakcity, Darwaza city, Shnyar city, etc. Remember thought that rent can be higher there between $400-550 dollars.Â
Yes, as far as I know you can rent a car and drive too. Just give it sometime, you can well get used to everything here,
Hope it helps:)
