xx,xxx households are in past-MOP blocks but were resold in the last 5 years — the new buyer's own MOP restarted, so these are excluded from the sellable-now pool.

Supply vs Demand Eligibility Pool by year within 4km · actual

In plain English: what’s free to sell right now — units that have already cleared their SSD/MOP lock-up.

Actual= booked supply only — real resale caveats coming off their seller’s stamp duty (SSD) holding period (3 or 4 years, by purchase date) plus GLS-awarded new launches. Every figure is a recorded transaction or an awarded parcel: what is genuinely on the SSD/MOP clock today. The demand:supply ratio (top row) is computed on this booked supply.

Neutral read: a higher ratio = demand outweighs supply; the trend shows if it’s tightening or easing. A haio estimate.

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.
