Do you mean receivership?

The city can’t repossess a house, a bank could file foreclosure proceedings and then file for possession if the property is mortgaged, most of these are not mortgaged.

Receivership is a long expensive process in the city. At the end of the process the city will own the property. The city also fails at maintaining the city owned vacant properties.
