Lease and eligibility context

About 58 years remain on the 99-year lease, based on its 1985 commencement year. This year-level figure is approximate.

A standard flat completed around 1979 would usually reach its 5-year MOP around 1984. 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.

200 flats: 1 × Executive, 179 × 3-room, 19 × 4-room, 1 × 5-room.
