Neutral read: bigger bars = more nearby flats able to list in that year; smaller bars = less new competition. A haio estimate — not advice on when to sell.
Two precision tiers: flats resold in the last 5 years count from the resale month (MOP actually runs from key collection); never-resold BTO flats are a year-level estimate from the block's completion year + 5 (+10 for Plus/Prime/PLH blocks).
MOP estimated as HDB completion year + 5 (standard scheme); +10 for Plus/Prime/PLH blocks. Able-to-sell figure nets out resale transactions in the last 5 years (those buyers' own MOP restarted). haio estimate — not guaranteed to reflect individual flat eligibility.

MOE Primary One priority (1 km / 2 km) is measured from your home’s postal address — see the full Valuation Report for your unit.
Straight-line (“as the crow flies”) distances per MOE’s official P1 registration method, measured from this property’s registered coordinates — not from a specific unit. Distance sets priority within each registration phase; balloting still applies — see MOE’s P1 registration rules.
A haio ranking signal, not a probability or advice — useful to time your own exit, to gauge incoming supply as a buyer, or to plan coverage as an agent. How this is calculated
