The AHG was first introduced on 3 March 2006 to help lower-income citizen families buy their first HDB flat.
Under the AHG, households earning below the monthly income ceiling can qualify for an additional subsidy (refer table).
In September 2019, AHG was replaced by the Enhanced CPF Housing Grants.
As with the current scheme, the enhanced grant is given to Singapore Citizen only (not Singapore Permanent Residence spouse or an undischarged bankrupt), and can only be used as capital payment for the flat purchase.
In addition to the current eligibility conditions to buy a new flat and the conditions of income ceiling and continuous employment, the family will have also to meet certain eligibility conditions, such as fulfilling a family nucleus, received any housing subsidies via various schemes and being not an undischarged bankrupt, to apply for the AHG.
