Supply vs Demand Eligibility Pool by year within 4km of 21 BO SENG AVENUE · 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.

Estimate only, not financial advice. A model-generated guide from public data — not a formal valuation; actual prices and bank valuations may differ, so verify before acting. haio accepts no liability for decisions made in reliance on it.

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.
