Housing grant is a subsidy given by the government in the form of CPF to make housing more affordable to buy.
Do you need to pay back the CPF Housing Grant?
Yes and No.
No if you are not selling your flat.
Yes when you are selling the flat. However it is not called CPF Housing Grant. It is hidden in the amount of CPF OA used. Upon the sale of flat, the sales proceed has to be returned back to the applicant CPF Account.
Hence HDB say you don't need to return the CPF Housing Grant to them and their statement is "right".
