Part of this is the belief that you need to have loads of projects and hundreds of units - this naturally brings "wise" buyers to you and makes them feel warm and safe. Besides that I honestly believe that the huge amount of buildings that continue to be built are no different to the "famous" Calis prom menus. The mentality is that you have to offer everything if you are serious about selling something, or you will end up selling nothing and nothing won't pay the bills. If a customer is lost because they saw something a little bigger, or a little closer to the beach, or whatever it was, the developer must find a plot and build these much sought after slightly larger properties, or must add something closer to the beach because that is what people are buying and if you don't have them you continue to fail to sell ever again. Just like the restaurant manager beating himself up because the two people next door eating chateaubriand would have been eating it in his restaurant if they hadn't dropped it from the menu.
In property terms it is of course total rubbish. You will never sell to each customer anyway and trying to plug the holes in your range is expensive and unnecessary. All that happens is you increase the number of empty units, often built with concrete and steel they still don't own, while using money elsewhere that the bank want back, bringing them ever closer to the fairly predictable abyss. To bring it right round to where this reply started, sadly your average customer in the Fethiye area these days associates company size with stability - at this time a totally flawed and dangerous view.
