Real estate investment volume is set to increase to some EUR 24 bn in Germany this year, according to Timo Tschammler, managing director of DTZ Germany. 'We won't see the massive increase we saw last year, but overall, market sentiment has improved slightly compared to 2010,' he said in an interview with PropertyEU ahead of the opening of MIPIM, the world's largest real estate fair which gets under way in Cannes on Tuesday.
