Straight-line (“as the crow flies”) distances per MOE’s official P1 registration method, measured from the development’s general location, not a specific block — for a precise check on your unit use MOE’s official School Query tool. Distance sets priority within each registration phase; balloting still applies — see MOE’s P1 registration rules.
Very low because this development is young — recently completed condos see almost no collective-sale interest.
ONE DUCHESS was completed too recently to attract redevelopment interest: little remaining-lease pressure, no realised plot-ratio headroom, and developers do not target near-new sites. We show a relative tier, not a percentage — and this tier comes from the project's age alone, not a model score.
A ranking signal, not advice or a prediction of any specific outcome. How this is calculated
Fewer neighbours are free or motivated to sell than at most comparable properties.
haio has transaction records for 13 units at ONE DUCHESS — the units we can track. Of those, 69% are past Singapore’s 3-year Seller’s Stamp Duty (SSD) period, so their owners can sell today without paying SSD, and 8% have been held for more than 10 years.
69%
Free to sell (no SSD)
9 of 13 tracked units are past the 3-year SSD period
91%
Sitting on a gain
10 of 11 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.

1 of 7exits had no exact area/floor entry match and were paired to the project's median launch PSF — a slightly coarser estimate for those rows.
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.

ONE DUCHESShas 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=13 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
