囧,那这个咋理解? Policies - Conditions After Purchase(source: http://www.hdb.gov.sg/fi10/fi10201p.nsf/WPDis/Buying%20An%20Executive%20CondominiumPolicies%20-%20Conditions%20After%20Purchase?OpenDocument&SubMenu=Policies) Selling of current HDB / DBSS flat in the open market If you currently own an HDB / DBSS flat, you and/or your spouse must dispose of the flat within 6 months from the date of issuance of the Temporary Occupation Permit in respect of the Executive Condominium (EC). If you intend to apply to purchase an EC where the Temporary Occupation Permit for the EC has been issued, you will be required to dispose of your existing HDB / DBSS flat within 6 months from the date the Developer serves the Notice of Vacant Possession on you. ------------------------------------------ 当然,这里的EC应该是没超过10年的,超过就和普通condo没区别了,不在此讨论范围内
