The market here is United States: every other developer whose head office is in the same country, because planning regimes and reporting norms move together within one. It is not a city, a sector or a size band. Read the two delay figures together. A median close to the market with a much better average means no single disaster; the reverse means one project is carrying the record. Time to deliver runs from the earliest start we hold to the completion itself — a construction start where a source gave one, otherwise a sales launch, otherwise the launch year read as its January. A handover the sources place only inside a year is read as that December, so a duration is the widest the record allows rather than the flattering end of it. Only delivered projects dated at both ends count, so it is taken over fewer projects than the delay figures, and a long build is not a fault: a tower is not a villa run. Sourced figures only, both sides, and values taken from documents held on file are excluded here — a developer who shares their records should not score better than one who does not.

Click any row for the sources behind it. Cost basis matters: an estimated cost, a construction loan and a sale price are different numbers. Each row states which one it is, so they are never averaged together.
