I lived and worked in Istanbul for 12 years. I have been back in the USA for the past 5 years. I have Turkish citizenship too.

When I left the country there wasn't any kind of mortgage system due to near hyperinflation. If indeed I can get a mortgage, I would surely return and buy a place to live. A 2 bedroom, bathand half flat would be ideal for me.

However, places like Fehtiye and others in the Med coast areas are all seasonal holiday communities. I don't think there is much call for EFL instructors there. I have heard that many large schools in Istanbul have sister schools now in the south due to the shift of population and early retirement of the neuvo riche'.
