HDB有特别要求已经有HDB，需要在租了另一套HDB后一个月里把目前自住的HDB租出去。 组屋屋主要租别的组屋得满足这个要求： Tenancy and property ownership status Tenants must not be tenants of public rental HDB flats or owners of other HDB flats unless they are: Divorced/ legally separated. In this case, only 1 party can rent a HDB flat from another flat owner Owners who are eligible to rent out their whole flat. However, they must rent out their own flat within a month after they have rented an HDB flat from another flat owner Tenants must not be owners of Executive Condominium units where the 5-year MOP has not been met. 租房间是没问题，只要实际住那边，像之前另一个层主说租了不去住，偶尔去看看是不行的。
