Overview: A group of Dutch, shady real estate dealers, real estate agents and entrepreneurs earns considerably during the Second World War to trade in Jewish real estate. Millions were involved with the purchase and sale of real estate of led jews. The real estate was - often for amounts that were far below the applicable market prices - purchased from the German occupier that the houses had expropriated. The transactions were kept by the German occupiers in the so-called Verkaufsbücher. Almost all books have been preserved. They contain the addresses and the names of the original owners, the brokers involved and the war copies, plus selling prices. And so a penetrating image of a criminal real estate circuit creates that gold earned money from expropriated, Jewish real estate. Were municipalities informed? Are they aware of the transactions? And how is the relatives? Are they compensated for expropriating the houses of their family?
