Why not cap rents and property valuation? It seems Berlin has done the former [1]. But it's not the first city to do so, Vienna is known to have a large public rent market to counter balance private development greed. In Spain, Andalucia (an area in the south of Spain), advocated during the political campaign to rent out thousands of flats owned by private banks, which in turn were bailed out with public money. Also Barcelona is going to implement measures to prevent the city to become an empty touristic resort with no much life beyond tourist apartments and hotels.
