Each sale is compared with its own block's median, so the figures show the floor alone, not newer or taller blocks; prices are brought to today with HDB's resale price index. The last column is this block's median $psf where it had 3 or more sales in the band. View and facing also play a part.
Lease timeline
- Now (2026): 64 years left. CPF and an HDB loan can be used in full if the youngest buyer is 31 or older (the lease must cover them to age 95); for younger buyers both are pro-rated. An HDB loan can run up to 25 years here.
- 2031: 60 years left. Full CPF use only if the youngest buyer is 35 or older.
- 2041: 50 years left. Full CPF use only if the youngest buyer is 45 or older.
- 2051: 40 years left. Full CPF use only if the youngest buyer is 55 or older.
- 2061: 30 years left. Full CPF use only if the youngest buyer is 65 or older.
- 2071: 20 years left. No more HDB loans: they must end 20 years before the lease.
- 2091: the lease ends and the flat goes back to HDB.
From HDB's rules as at October 2026: CPF use and the HDB loan are pro-rated when the remaining lease doesn't cover the youngest buyer to age 95, and HDB loans must end 20 years before the lease. Banks set their own limits on short leases. Rules change: check with HDB and CPF before you buy. How lease left affects price →
