Redfin market data (county + ZIP), via Lotvox. As of 2026-09-30. Normal = same-month median of monthly rates, minimum 3 same-month points. Source window 3 months (flows shown per month). Aggregated over a fixed panel of 96 zips — the panel is fixed so a change in who reports cannot look like a change in the market. months_of_supply is not published at this grain (0 non-null rows measured); derived here as active listings / closed sales per month.
