The marker is an approximate site centroid compiled by PropertyInsider.sg, not a surveyed boundary. Station distances are straight-line, measured from the site centroid to the midpoint of a station’s published exits (LTA MRT/LRT exits dataset) — not the distance to the nearest exit, and not a walking route. Walking times are an estimate only and are omitted beyond 2 km. Base map tiles are © OneMap / Singapore Land Authority.

Prices, sizes and unit counts are compiled unit by unit from the Tower View extraction dated 19 Jun 2026. Sold figures cover transacted units only; the available column counts unsold units of the same type. Averages vary by floor, stack and facing — ranges matter more than any single number.

How D09 resales have performed
Capital appreciation context for The Collective At One Sophia: what sellers of completed condos in the same district actually realised on 8,103 matched buy-and-sell pairs (March 1995 to August 2026), including the 16.3% that sold at a loss.
Read this first: these are completed matched exits, profitable and unprofitable, over March 1995 to August 2026. A median describes what the middle seller realised — never the probability that any particular purchase will do the same. Note also that an owner sitting on a paper loss can decline to sell, so the true loss rate across all purchases is higher than the 16.3% recorded on completed sales here.

Land cost versus comparable sites
What the developer paid for this site, ranked against the sites most like it — same market segment and planning region where we have enough of them, widening only if we do not. Land is the largest single input into a launch price and it is fixed two to three years before the show flat opens. Every tracked site sits on the land cost tracker.

Distances are straight-line estimates computed from project and school coordinates and shown to 2 decimal places — they are not the official home-school distance.

For P1 registration, verify the exact 1km/2km status with the OneMap School Query tool, which applies MOE’s official measurement.

The split shown is the first month’s instalment, not an average: early payments are mostly interest and late ones mostly principal, while the monthly figure itself stays level. This is the loan only — it excludes stamp duty, legal fees, maintenance and property tax, and a home bought under construction draws the loan down in stages rather than all at once. What a bank will actually lend you depends on the LTV limit, TDSR and, for HDB flats and developer-sold ECs, MSR. Work those out on the affordability calculator, stamp duty calculator and progressive payment calculator. Estimates only, not financial advice.
