I have looked at investment in Turkey in the past. I spent many weeks there in the coastal resorts. The economy was a basket case then so current growth needs to be measured against very low levels the country traditional had.
Property generally in resort terms is poorly built, low quality materials and designed with planning hap hazard at best. The tourist traffic is increasing but being an Islamic country, albeit moderate does hold it back. Then there is the constant earthquake risk, natural disasters and some terrorist activity. Political stability also is a question with the military always threatening.
Istanbul is a vibrant interesting place, wonderful friendly people but I would not buy property there for so many reasons.
The talk then was Turkey will soon be in the EU, so invest now before it becomes the new property hot spot. Well that didn’t quite happen did it and nor is it likely to in the near future, if ever.
