St. Louis Section 8 Investing: A-Grade Voucher Math
St. Louis City is an A-grade Section 8 market on CloseHound, where voucher rent routinely beats the open market and supports strong cash-on-cash before financing. The median 3-bedroom voucher pays $1,400/mo against a $140,000 supported price, with moderate costs — about 1% property tax and 0.9% insurance — across the 9 screened ZIP codes in this Midwest market.
Even at an A grade, the discipline still applies: the screened voucher range is fairly tight at $1,270 to $1,510, so paying above the $140,000 supported price quickly erodes the edge. Underwrite each address against its specific ZIP. Screen any St. Louis property free on CloseHound to confirm where the math lands.
