Remember that while Berlin apartments may seem cheap by Irish standards, there is one fundamental difference that you need to take into consideration when deciding on an investment strategy in that city. Most residents rent, they don't buy. Therefore there is not a very strong local market, even in good times, for properties like this, so the best that can be hoped for is a price related to the rental return. There is no possibility of ever getting a windfall price for one of these when you sell it; there just isn't a big demand-driven market there, never will be. There will never be a boom such as we know of in markets where most people own their own home.
