You or your household (essential family members in the application form) will be considered as first-timer applicants/household if you have not taken any form of housing subsidies.
A subsidised housing unit refers to:
Each eligible household may take up to 2 housing subsidies. If you have taken one form of housing subsidies, you are considered second-timer applicant. Second-timer applicant must pay resale levy if they buy next subsidised flat. If you have enjoyed two housing subsidies, you are not eligible to apply or be listed as an essential occupier in a flat application to buy a flat direct from HDB or a resale PLH flat on the open market.
For those married or fiance-fiancee couples where one party is a first-timer and the
other party is a second-timer, HDB will exercise flexibility to treat those couples as
first-timer households in the balloting process and under the priority schemes.
Basically, they still enjoyed the same first-timer privileges if they are both Singapore Citizens/ 1 Singapore Citizen and 1 Singapore Permanent Resident.
This only applicable for couples who had remarried or are remarrying each other after their divorce finalised.
