Saint Louis City

Saint Louis City posts a gross rent-to-price ratio of 8.95%, which lands it firmly on the cash-flow end of the spectrum for a major Missouri market. The median home price of $186,876 paired with median rent of $1,394 produces a cap rate of 5.82%, a figure that compares favorably against most gateway cities and puts the market in legitimate income-producing territory. The appreciation story is a different conversation: home prices are down 0.63% year-over-year, the appreciation score sits at 47 out of 100, and the overall score of 69 reflects a market that earns its marks through income math rather than price momentum. An investor underwriting purely for growth will find little support in the current numbers.

The cash-flow score of 90 and affordability score of 90 tell you exactly who this market is built for: the yield-focused buyer who wants low entry prices and rents that cover the mortgage. At 20% down, the modeled cash-on-cash return is negative at -2.04%, with estimated monthly cash flow of -$73. That figure deserves scrutiny, not dismissal. The model assumes $488 in monthly expenses on top of a $980 mortgage at 6.85%, and a buyer who moves down the price stack below the county median, manages vacancies tightly, or captures a unit with above-median rent can realistically push into positive territory. The 5.82% cap rate tells you the unlevered return is there; the financing environment at 6.85% is what compresses the leveraged return. This is also a natural fit for a value-add operator: a market with median prices under $187,000, a cash-flow score near the top of the range, and a 0.63% annual price decline creates negotiating room that higher-priced suburban counties cannot offer.

On carry costs, the combined monthly tax and insurance estimate is $220, which is a manageable line item relative to the $1,394 median rent and already baked into the $488 expense figure. The state-average effective property tax rate used here is 0.97%, which Missouri's Tax Foundation data places in a normal range, so it does not demand special attention the way a 1.5%-plus rate would. That said, Saint Louis City operates as an independent city rather than a county, and actual assessed rates and local levies can diverge meaningfully from the state average used here. Any serious underwrite should pull the actual parcel-level tax bill rather than relying on a state-average proxy.

The neighbor comparison sharpens the case for Saint Louis City as a cash-flow play. Buchanan County comes in at a similar overall score of 69 with a comparable median price of $182,875, but its rent-to-price ratio drops to 5.79% and median rent is only $883, a full $511 below Saint Louis City. An investor choosing between the two is giving up roughly $500 per door per month in potential gross income for virtually the same purchase price. Butler County's ratio of 6.73% and $900 rent offer better yield than Buchanan but still trail Saint Louis City by a meaningful margin. Jefferson County has a higher median rent of $1,462 but a much higher entry price of $281,743 and a rent-to-price ratio of 6.23%, which means the income efficiency is lower even though the absolute rent is comparable. Clinton County and Maries County lack rent data in this comparison set, limiting a direct yield analysis. Across the peer group, Saint Louis City's 8.95% ratio is the clear outlier, which is the core reason to choose it over a neighbor when cash-flow efficiency per dollar deployed is the primary objective.

The risks specific to Saint Louis City are worth naming directly. A population of roughly 298,000 in a market with flat-to-declining prices and a stability score of 50 out of 100 signals demographic and economic softness that an investor cannot ignore. Markets with negative price appreciation and middling stability scores can become value traps if vacancy trends deteriorate or if the renter pool contracts. Concentration risk is real: a portfolio built entirely in a single sub-market of one independent city, with no suburban diversification, amplifies exposure to any localized policy or economic shift. The data does not support claims about vacancy rates or crime, but a thorough due-diligence process for this market should include neighborhood-level rent collection data, actual vacancy surveys, and a review of any local rent-regulation ordinances before committing capital.
