What moved between two reads

A 60% fall in a “from” price is a project that started quoting a studio where it used to quote a three bedroom. The same building, a different cheapest unit. That is why this page ranks on how often the quote moved, not on how far.

Across 2,283 projects dated in both reads, 362 handover dates read earlier on the second portal against 105 that read later. A measure of delivery slippage cannot run 3.4 to one in the direction of buildings getting sooner. That ratio is the noise floor of comparing two portals, and it is the reason this table is published with both columns and no on-time percentage anywhere.

Projects matched on normalised title plus developer (no shared id exists). A handover counts as moved later only when the stated date moved to a later quarter; the July side often carries a quarter-end date, so a move within the same quarter is rounding, not a revision. Dates that moved earlier are reported but never ranked on, because a date reading earlier on a second portal is far more often disagreement between the two sources than a project pulled forward. Two different portals read three weeks apart, not two reads of one listing: a difference can be a portal disagreement rather than a developer revision. Every further dated read adds a point of comparison. Only developers with at least 10 projects dated in both reads appear. Nothing here is an on-time rate: a project is counted when its stated date differs, not when a building was late, and no handover in this set has been observed happening.

Every row behind this table compares two different portals, not one portal restating itself: 1,405 of 1,405 are cross-source, which is all of them. So a project moving from on sale to sold out here is one source disagreeing with another about its status three weeks apart. It is a lead worth chasing and it is not a sale, and nothing on this site records it as one.

The table shows the 8 commonest of 14 distinct transitions across 435 projects, so this is a handful of shapes rather than noise. The other 970 rows in the feed are entry price and handover date, which have their own sections above and are computed from fuller per-project files.
