限购 property-purchasing limitations-英语点津

日前，“全国最严格限购”在京出台。新政提高了外地人的购房门槛，在一定程度上提高了外地投资客进入北京楼市的门槛。

请看相关报道：

Migrant buyers blocked by tough new property policy: Millions of migrant families in Beijing will be blocked from owning their own homes under strict new regulations aimed at cooling the capital's property market.

外地购房者因严格的房产新政购房受阻：按照新出台的的“京版国八条”，北京数百万户外地户籍家庭将无法购置新房，该项新政旨在给北京的房地产市场降温。

文中的migrant buyers就是指“外地购房者”，migrant指“移居者”，这里是指户籍不在北京的购房者。楼市“限购令”的出台给市场带来不小波动，那么“限购”英文该怎么说呢？来看下面的报道：

The central government will expand property-purchasing limitations to second- and third-tier cities as it steps up efforts to cool the real estate market, a report said on Sunday.

周日有报道称，中央政府将把“限购令”范围扩大至二、三线城市，进一步为房地产市场降温。

Property-purchasing limitations就是“限购”，也称为homebuying restrictions。在second- and third-tier cities（二、三线城市）纳入限购范围前，first-tier cities（一线城市）已纷纷出台限购措施。
