Methodology: Bedroom-level rent medians come from HUD Fair Market Rent data calibrated to the Zillow Observed Rent Index (ZORI) for Affton, which serves as the citywide anchor. When the HUD bedroom values exceed the ZORI city median (a common quirk in luxury markets and small samples), bedroom values are proportionally scaled down to align. Income required uses the standard 30% rent-to-income guideline. Comparison rankings use the same data month across all cities (July 2026) and exclude cities with median rent below $400 or above $20,000.
