Investment Summary

As of 2026, rental properties in St. Louis, MO yield a 4.3% cap rate. Median home price is $231,511 with 3-bedroom rents at $1,485/month.

St. Louis is a moderate market — workable but not exceptional for cash flow. At $231,511 median home price, St. Louis is affordable by national standards and within reach for most conventional loans. With 3-bedroom rents around $1,485/month, the 4.3% cap rate tells the story. Cash flow is deeply negative at -$396/month with standard assumptions. This market requires appreciation to justify the investment.

At 0.61% on the 1% rule, rents are low relative to purchase prices. You'd need a significant discount from asking price to make the numbers work. DSCR of 0.68 is below 1.0, meaning rental income doesn't cover the mortgage. DSCR lenders will likely decline this market at current prices.

Bottom line: Consider St. Louis only if you believe in long-term appreciation. The numbers don't support cash flow at today's prices and rates.
