不过网上总结说“In general, decoupling makes economic sense when buying a second property which has a higher value than the 1st property. Or in cases where the value of the 1st and 2nd property is close to each other”
如果选项一的话,以后再去买一个小一点的房,如果要decouple 这个2M的房产,需要付的seller stanp duty and BSD还有legal fee也不便宜呢。具体多少我还不知道咋算。。。
