Rents are HUD Fair Market Rents for FY2026 (the 40th-percentile gross rent, utilities included, for the metro area — a modest, typical unit, not a luxury one). Take-home is for a single filer with no pre-tax deductions, 2026 tables, city tax where it applies. The 30% rule compares rent with take-home pay, not gross.
