Lease and eligibility context

About 62 years remain on the 99-year lease, based on its 1989 commencement year. This year-level figure is approximate.

A standard flat completed around 1989 would usually reach its 5-year MOP around 1994. The actual MOP starts from each owner’s key collection date, and special schemes can differ. Check HDB’s rule ↗

Indicative only. Check your dates and eligibility with HDB, CPF and your conveyancing adviser.

90 flats: 72 × 4-room, 18 × 5-room.
