Methodology. All metrics derive from the Placesi behavioral event store (searches, views, saves, inquiries, mortgage interactions) and the verified listing inventory, computed nightly. Behavioral series begin August 2026; earlier periods are backtest simulations. Demand/Supply uses qualified weighted demand over active inventory. Heat is a 0–100 composite: 30% demand growth, 25% supply pressure, 20% mortgage intent, 15% search-to-inquiry conversion, 10% inventory trend — every score decomposes into these inputs.
