German commercial real estate investment volumes are expected to double in size this year, reaching as much as EUR 20 bn by the end of 2010, according to Oliver Obert, managing director of BNP Paribas Real Estate Germany. ‘It is going to be the third best year in history after 2006 and 2007,’ Obert said in an interview at EXPO REAL. The figure compares to some EUR 10 bn recorded a year before in the market.
