最重要的几点：
1）价格不能随便放了，涨幅必须在已有最高成交价的10%以内
2）买家必须先拿到HFE letter 才能看房
3）双方都是通过singpass 才能登录
4）卖家只能登一条广告
Sellers will be prompted if their listing price is at least 10 per cent above the highest transacted price of similar units nearby in the past six months. They will also receive a prompt if the price is abnormally low.
Any prospective flat buyer can browse the resale listings on the HDB flat portal, but only those with a valid HFE letter can obtain the sellers’ contact details and schedule viewing appointments.
