En-Bloc Likelihood
High likelihood
Ranks near the top for redevelopment interest among private condos.
THE SUNNYDALE 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: 25 years old · 70 years left on the lease · 51 past en-bloc deals in the district
Based on 4 comparable past collective-sale deals (RICHARDS MANSIONS 2010, PARRY GARDENS 2005, CALISAY 2007).

Selling Pressure
haio estimate
Higher selling pressure
More neighbours are free — or motivated — to sell than at most comparable properties.
haio has transaction records for 71 units at THE SUNNYDALE — the units we can track. Of those, 90% are past Singapore’s 3-year Seller’s Stamp Duty (SSD) period, so their owners can sell today without paying SSD, and 65% have been held for more than 10 years.
90%
Free to sell (no SSD)
64 of 71 tracked units are past the 3-year SSD period
74%
Sitting on a gain
60 of 81 resales sold above what the seller paid
“Free to sell” means the 3-year Seller’s Stamp Duty window has passed, so selling now incurs no SSD penalty — a proxy for how many owners could list without a tax cost. “Tracked” units are those with a purchase on record; not every unit has changed hands.

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.

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

Distances are measured per block (straight-line, MOE method) and the nearest block’s distance is shown; where blocks differ, the qualifying blocks are named. The balloting distance is from your exact unit’s block. Distance sets priority within each registration phase; balloting still applies — see MOE’s P1 registration rules.
