The US government produces a vast array of real estate-relevant data at the federal, state, and local levels. At the federal level, agencies such as HUD, the FHFA, the Census Bureau, the USDA, and the GSA publish housing statistics, price indices, and federal property inventories. At the local level, county assessors, recorders, and planning departments maintain the primary records for tax assessments, zoning ordinances, and building permits. This category is particularly important for researchers, policy analysts, and proptech developers looking for free or low-cost data foundations.
