Zillow Research
Monthly US metro home-value momentum intelligence from Zillow Research's Zillow Home Value Index (ZHVI), metro grain (keyless public CSV, 894 US metros + national reference, 2000-01 -> present, smoothed seasonally-adjusted typical home values in $). Per (month, metro): home-value level, month-over-month, 12-month and 3-month-annualized momentum, acceleration in percentage points, deviation from the national home value, per-month cross-sectional dense rank / percentile / z-score of appreciation, a documented 0-100 home-value heat score (fast vs peers + expensive vs nation + accelerating) with heat tiers, and hot/cold/cooling/36-month-record flags. Upstream coverage gaps stay null, never imputed. The owner's wealth complement to the ZORI rent-pressure panel: appreciating metros expand household balance sheets (Shopify demand), cooling prints flag churn/pause risk (Stripe subscriptions), and the ranks heat-map sales territories (HubSpot) — joinable on ISO month + metro.
