Nearly all the business in Ölüdeniz have rents in US$. In Hisarönü they are sometimes in GBP. In Fethiye its a mix, they can be in US$, Euros, as along the new kordon and also in TL which thankfully applies to us. I have no idea about Çaliş but do know rents are cheaper there than elsewhere.
There are also a lot of places as Karaokemark has said particularly in Çaliş and Hisarönü/Ovacık who own the land and definitely have the advantage over those that have to pay rent.
Turkey produces very little rice, it is imported in the main from China and the States and is therefore bought and paid for at the Dollar exchange rate at the time.
