In case you haven't yet discovered this, there is a really good app. for owners to use to advertise their property for rental or purchase. It's called KalkanRentBuy and is the only app I could find which specifically relates to Kalkan (which makes it a good place to advertise).
It's very easy (and cheap!) to advertise your property on there and the guy who developed the app is very helpful, responsive and professional to deal with.
(I have no business or other relationship with the app. developer, but I have just put our old-town house for sale on the app.)
