Not thick, but there does seem to be just a handful of leaders and shedloads of followers - just look at the majority of seafront menus to see that, hardly a dish different between some of them.
I don't actually think there's much negative in the local property market - I've said before that when living in Turkey and exhibiting at the various UK overseas property exhibitions, I didn't see anywhere that gave pound for pound what Fethiye has to offer. You can get a two bedroom apartment with shared pool for 40k, get the history, weather, friendliness (and so the list goes on). I saw cheaper but bland places being promoted, and I saw possibly more refined/finished places but at a huge premium. I still don't think anywhere comes close.
I never fell out with the property industry in Turkey - you need to be careful as you do anywhere - if anything I became disillusioned with the customers not the builders...
