4-room sales over the last 5 years in blocks within 500 m in Yishun, this one included (462 sales).

Lease timeline
- Now (2026): 90 years left. The lease covers any buyer to age 95, so it doesn't limit CPF use or the loan. An HDB loan can run up to 25 years here.
- 2047: 70 years left. Full CPF use only if the youngest buyer is 25 or older.
- 2057: 60 years left. Full CPF use only if the youngest buyer is 35 or older.
- 2067: 50 years left. Full CPF use only if the youngest buyer is 45 or older.
- 2077: 40 years left. Full CPF use only if the youngest buyer is 55 or older.
- 2087: 30 years left. Full CPF use only if the youngest buyer is 65 or older.
- 2097: 20 years left. No more HDB loans: they must end 20 years before the lease.
- 2117: 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 →
