The datasets behind every number.

RentalAnalytics is built on public datasets first. Private/estimated sources are clearly labeled at every touchpoint.

Primary sources (public domain)

HUD Fair Market Rents (40th / voucher)

Published annually by the U.S. Department of Housing and Urban Development. Targets the 40th-percentile gross rent; used to administer Section 8 voucher programs. Shown on the Rent Estimator as the labeled 40th / voucher number — not the hero “market” figure. Current product vintage is FY2026 (effective 2025-10-01). The 15 prebuilt city markets use the revised county-level metro FMR workbook. The Fort Wayne, IN HUD Metro FMR Area uses the revised Small Area FMR workbook (ZIP-level), including ZIP 46835.

HUD 50th-percentile rents (not FMR)

A separate HUD series of median (50th-percentile) gross rents by FMR area and county. HUD states these are not Fair Market Rents. This is the primary lift for the estimator hero: ZIP FMR/SAFMR × (area 50th ÷ area 40th). Area/county only — there is no ZIP 50th file. Fort Wayne’s 50th and metro-wide 40th come from the official FY2026 workbooks.

U.S. Census ACS B25031 & Housing Vacancy Survey

ACS 2024 5-year table B25031 is median gross rent by bedrooms at ZCTA — the estimator’s second anchor, shown with the Census margin of error. It is an occupied-unit median, not asking rent. Vacancy context on city pages still uses ACS / HVS blends labeled estimated.

Secondary sources (labeled as estimated)

Zillow Research ZORI

The Zillow Observed Rent Index. A widely-cited monthly typical-rent series (about the 35th–65th percentile of listed rents, stock-weighted). ZIP files are all-homes dollars, not bedroom rents. We do not assign a ZORI ZIP all-homes dollar to a 0–4BR estimate. Metro asking-rent change was reviewed as a possible aging overlay and omitted from the hero where it is not clean across covered metros.
