ZCTA ≈ USPS ZIP. ACS 5-year 2023 lags construction. Units-in-structure is Census standing stock (2-unit vs 3–4 vs 5–49 vs 50+), not the live FMLS card. SAFMR is a bedroom-specific HUD voucher benchmark, not asking rent. LIHTC / assisted-MF are inventory of record and belong on apartment pages. 5+ permits are county BPS 2025 allocated by ZCTA housing-unit share. Brokerage is Georgia-only.
