Rayk150 I think you are oversimplifying things considerably. No more German's are buying in Eastern Europe than any other nationality, in fact considerably less than some. Most, if not all of the German's buying in Eastern Europe, and elsewhere in the world fall into two category's, the very few people in Germany able to afford to buy their own home in Germany, and buying a second, or holiday home, and those unable to afford a home in Germany and investing elsewhere in the hopes of making a quick profit and using it to get onto the German property ladder.

Everybody knows you aren't going to make a big profit quickly in Berlin, but rental rates are growing accross the board and have been for a year now, which is almost unprecedented. As rental rates continue to grow, the near certainty of maintaining a rental income for whole years at a time translates into yields as impressive as some of the world's hottest emerging markets, but with the security of being in an established European country, with a proven track-record of economic stability and sustained/sustainable growth.
