I live in Dalyan, live on my own, and am happy to offer any info I can help with. So much depends on your own particular life style- if you are willing to share any specifics as to how you envision your life here, I can give some possible costs. Things like: do you have, or will you be getting pets, are you planning to get a car, how old you are (that determines health insurance costs), do you smoke, what type of foods do you plan on eating, do you regularly plan to go out for meals, or socialize at quizzes or bars? So many variables, depending on your wants and needs. I have single friens who spend 2 or 3 times what I do monthly, and I have friends who spend less than me! If you send me an email address, I will put some info together for you over the next week.
You've made a good choice with Dalyan.
