En-Bloc Likelihood

Moderate likelihood

Ranks in the upper third for redevelopment interest among private condos.

COSY 23 is ranked for collective-sale (en-bloc) potential over the next 5 years, relative to other private condos. We show a relative tier, not a percentage — the ranking is reliable, an exact probability is not.

Driven by: 27 years old · Master Plan plot ratio 2.8 · 38 past en-bloc deals in the district

Based on 4 comparable past collective-sale deals (PADDY GREEN 2012, BAODE BUILDING 2022, PALACE MANSIONS 2010).

Profit & Loss

haio estimate

3 realized resale exits at COSY 23 over the 5y window — 3 profitable, 0 at a loss, averaging 4.26%/yr.

Profit Distribution

Unit Type	Volume	Holding (avg)	Annualised (avg)

Total	3	25y 6m	4.26%

Loss Distribution

No loss-making resales in this window — every matched exit sold above its matched entry price.

Realized resales: each resale / sub-sale (the exit) is matched to a comparable new-sale (the entry) at the same project by floor band and strata area, then the annualised return is (exit ÷ entry) ^ (1 ÷ years held) − 1. URA caveats only. haio estimate — URA masks unit numbers after May 2021, so entries are matched by area + floor, not exact unit. Executive Condos are shown as a separate segment.

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.

Exit Risk

haio unit-level records

COSY 23has had fewer than 3 resales in the last 12 months, so there is no honest “today’s price” to score against. Where current owners entered is still on record below — n=11 traced current owners, 100.0% unit-exact.

The headline share is an exact count over haio’s unit-level records — one entry price per traced current owner. “Today’s price” is the last-12-months resale median, an anchor, not a valuation. In appreciated projects most owners naturally hold cheaper — long holders rarely sell low, so read it with the SSD-free share. Not advice. How this is calculated
