Excluding grants, a 4-room HDB flat costs around $270,000. However, under the Enhanced CPF Housing Grant (EHG), which awards between $5,000 to $80,000 in terms of grants based on you and your partner’s eligibility criteria, a 4-room HDB flat can cost from around $192,200 to $267,000.

How big is a 4-room HDB flat?
