New restrictions were placed on housing buyers in Beijing and Shanghai, in an effort to cool housing prices. Beijing municipal government now allows unmarried persons to buy only one home, increases the minimum down payment on a second home, and puts a 20% capital gains tax on sellers of homes. In Shanghai a similiar tax was placed. The tax replaces a 1-2% tax on housing sales. A government survey shows housing prices up 3.1% in Feb 2013. The central government is preparing a national property registration system by the end of 2014. This will make it possible to place annual taxes on residential property.
