Shanghai has announced a batch of tightening policies in its latest bid to stabilize the property market which has been seeing growing signs of overheatedness. Effective today, the number of homes owned by people who have been divorced for less than three years will be calculated based on what it was like when they are married, the city’s housing authorities, as well as a number of government watchdogs, said late yesterday in a joint statement. Under the city’s current home purchase restrictions, local families are allowed to purchase two residential units at most while non-local families are entitled up to one home.
