Berlin is not “the poor but sexy city” anymore, as the former mayor, Klaus Wowereit, said. A dynamic growth has been set up. The real estate prices rose by 10% last year. “All indicators plan that the price increase will keep going: 15 000 accommodations are missing per year” and the new law on the rent regulation system, which has come into force on June 1st, does not seem to stop this market pressure. It appears to be even “counterproductive”, Arnaud Schott noticed. “I get the impression that everything remains the same as before with just the difference that there are less available apartments on the market”.
