St. Louis, MO: Rental Property Market Guide

Updated March 2026 · Pop. 281,764

St. Louis is a city that gets overshadowed by its own crime statistics. Yes, the per-capita crime rate is high — but that number is misleading because St. Louis City is an independent jurisdiction separate from St. Louis County. The "city" is only 61 square miles with 280,000 people. The metro area is 2.8 million people, most of whom live in safe, thriving suburbs. For investors, this distinction matters enormously: the city's notoriety keeps prices artificially low while the metro's economic reality — 12 Fortune 500 companies, two world-class hospital systems, and one of the best university corridors in the Midwest — creates genuine rental demand. The result is 8-9% cap rates in a metro that by rights should price closer to Kansas City or Indianapolis.

City vs. County: Two Different Markets

St. Louis City and St. Louis County are legally separate entities with different tax rates, school districts, and services. The city has higher property taxes but lower purchase prices; the county has better schools and lower crime but higher entry points. Most serious investors own in both. City investments (Benton Park, Tower Grove, Shaw, Dutchtown) are cash-flow plays: $100-180K properties renting for $900-1,200/month. County investments (Maplewood, Webster Groves, Kirkwood, Affton) are balanced plays: $200-300K properties renting for $1,300-1,700/month with lower vacancy and longer tenancy. Start in the city to learn the market, then use the cash flow to fund county purchases.

The South City Gold Mine

South St. Louis City — roughly from Soulard south to Carondelet — has the best risk-adjusted returns in the metro. Benton Park (63104) is the most established investor neighborhood: renovated brick bungalows sell for $180-250K and rent for $1,200-1,500. Tower Grove South (63116) is similar but slightly cheaper. Dutchtown (63116/63118) is the value play — properties under $100K renting for $800-950. The tenant base in south city is remarkably stable: these neighborhoods have strong community identity, active neighborhood associations, and residents who've lived there for decades. Many renters in south city choose to rent in these specific neighborhoods rather than buy in cheaper areas, which creates consistent demand.

The Cortex Innovation District

Cortex is St. Louis's technology and innovation hub — a 200-acre district in the Central West End that houses Microsoft, Square (Block), Centene, and dozens of biotech startups. Over $700 million has been invested in the district since 2002. For rental investors, Cortex creates a pocket of high-income tenant demand in an otherwise affordable market. Properties in the Central West End (63108), Forest Park Southeast (63110, locally known as "the Grove"), and the Delmar Loop area (63130) attract Cortex workers, Washington University employees, and BJC Healthcare professionals willing to pay $1,200-1,800/month for walkable urban living.

The Brick Factor

St. Louis is a brick city — 95% of the housing stock is brick or brick-veneer. This is both an advantage and a cost. Brick homes have lower maintenance costs for exterior upkeep (no painting, no siding replacement) and are more durable than wood-frame construction. However, tuckpointing (repairing mortar between bricks) is a necessary expense every 20-30 years and costs $5,000-15,000 depending on the size of the building. When evaluating St. Louis properties, check the mortar joints — if you can crumble mortar between your fingers, tuckpointing is needed. Chimneys are especially vulnerable. Budget for this in your capex reserves.

Why Investors Underestimate St. Louis

St. Louis gets written off because of the crime headlines, the population decline narrative (the city has been shrinking since 1950), and the lack of a sexy growth story. But here's what the numbers actually show: the metro area's population is stable at 2.8 million, BJC HealthCare and Mercy are actively expanding, Centene (Fortune 500, now based here) has 15,000+ local employees, and Washington University's endowment ($12 billion) ensures the institution's gravitational pull on the local economy for generations. Properties that should trade at 6% cap rates based on the economic fundamentals are trading at 8.5% because investors are scared of the crime stats and don't understand the city-county distinction. That fear premium is your opportunity.
