MUNICH - A quarter of German local authorities want to sell off their housing stock, with and medium-sized towns and cities particularly keen to get sell off part of their housing stocks, a new survey by consultancy firm PriceWaterhouseCoopers (PWC) shows. Towns in the west of the country are more ready than towns in eastern Germany. East German authorities prefer to demolish unwanted stocks, which have high vacancy rates, rather than sell them, PWC said.
