关于EC的MOP，我看到HDB是这样解释的Minimum Occupation Period (MOP) Sale of EC You have to occupy the EC for 5 years from the date of key collection before you can sell it in the open market. Essential occupiers in EC Occupiers who are essential in forming a family nucleus with you in the EC application must continue to be listed in the application and stay in the EC during the 5-year MOP. They cannot make a separate application, or be listed as occupiers in another application to buy an HDB flat or another EC within the MOP. 这个五年MOP只针对你卖掉EC或者申请新的HDB/EC，那是不是意味着这五年之内其实是可以买私人公寓的？

买二手hdb后可以买公寓么？也要等五年嘛？买二手hdb后可以买公寓么？也要等五年嘛？
