Punggol is a town of waves. Blocks were handed over as BTO launches came through, so owners along one LRT loop often share a key-collection date, a flat type and a selling date.
When that date arrives, many list within the same few months, and sellers compare agents who know their part of town.
Buyers come from two directions: couples who missed a BTO ballot and want a resale flat now, and families in Sengkang or Hougang who want a waterfront address.
Sellers must have finished the minimum occupation period (the years an owner must live in the flat before selling), and buyers need an HDB eligibility letter. Plus and Prime flats carry a longer period than standard ones, which changes selling timelines.
Executive condominiums and private developments are a second market. Sellers can check your registration on CEA's public register.
