After that an analyzation of possible indicators which are linked to the two largest housing bubbles: the The Subprime Crisis in in the USA of the former decade and the housing bubble in Japan in the middle of the 90s will be done and a comparison of those crises will be given.Based on those findings the development of the current real estate situation of Germany and an overall evaluation of possible legal and political instruments which are supposed to protect from a pricing bubble will be done. The findings are based on literature review and include an empirical part with expert interviews when it comes to the risk of having a housing bubble specifically in Germany.
