Depends on you really and what you like to eat.
If you can buy a property here then do so, as rent will take 45 per cent of your total monthly budget, if I work on averages from what my friends spend.  Contrary to what people say the rents are NOT cheap in comparison to cost of living unless you're prepared to put up with a trek out of the main towns and very poor standard of accommodation. Utilites are cheap as is bread and vegetables. I bought two loaves, milk, peppers, lettuce, cucumber, peaches, pears and a few other things for just under 8 dinars.
Electrical things are expensive as is decent furniture - eg on a par with Europe but lack of choice. However, there are decent stores where you can pick up a dinner plate for a dinar.  You just have to shop around.
The people that I know from the UK that I know manage on £100 (UK stirling) per week. That said that factors in food, entertainment and bus travel only but NOT car expenses, medical expenses, emergencies, clothing or insurances etc. I was surprised how expensive my 2 month 3rd party car insurance was.Â
As you guess they see a white face and they add 50 per cent on .. be careful on that.
Vegetable/fruits are best bought in local markets (yet to find one) and bread is very cheap as are the good quality boulangeries. Fruit juice is lovely and so is the *unprepared" fish. You can buy bag fulls of cous cous / rice / pasta for not much.Â
Talking to locals, a waiter only earns (less tips) 200 dinars a month; a manager in tourism 300 dinars a month and a professional like a lecturer about 800 dinars a month and some keep a wife and child on that so there must be a way to do it! That said most don't have a car, go on holiday or buy many clothes.Â
I'm not to bad at the moment money wise (but hope to work and generate some income) but it will be very tight next year when I have to really budget. But seek out local places to keep coffee prices down.. you may be the only woman but hey, so am I! Again, eat away from tourist areas and you can get some tasty things for a few UK pounds.
Don't know how useful that is or not. I can always check with the people I know here to get a more accurate picture if you like.
I know I'm here but personally, unless someone is mad keen to come I'd advise against it unless you're prepared to get out of western thinking and into the local life. Â
If you're a single woman you will be a target in every way. I've been targeted on many occasions but am not silly .. also I've been very lucky in finding a professional family (mostly surgeons/doctors) and they've been a Godsend in helping me settle in as has my friend from the UK whose lived here two years.
take care Carole
