German universities have registered a significant increase in student numbers in recent years. Almost 2.7 million students were enrolled in Germany during the 2014/15 winter semester. However, certain cities have already started to witness a decline in student numbers.
Since there is a lack of affordable small residential units, students arebeing squeezed out of the rental apartment market.
Private investors take advantage of that lack of supply and are building new properties on a large scale.
