Investy, I think you are generally right except one small detail, which is (talking for Turkey) the fact that you can get a property with year round rental depending on where you invest.

As an example, if you purchase a descent property in a big city (i.e Istanbul, Ankara, Izmir) you can be almost %100 sure that you'll rent it pretty easily your property for an amount that will cover the mortgage interim payments etc.

However, it is slightly different for costal areas (Aegean, Mediterranean). In these locations (except the ones guaranteed by the developers), its a little more difficult (for now) to guarantee a year round rental. However, the interesting thing here, is the fact that once rented, you can get a pretty descent rental income for (on average) 4-6 months.
