Saint Louis City market analysis
Saint Louis City sits at a 0.875% gross rent-to-price ratio, which puts it firmly on the cash-flow side of the spectrum, at least on paper. The cap rate comes in at 5.69%, respectable for a city with a median home price of $176,514, and the affordability index of 92 signals that entry costs are genuinely low relative to most metros. The problem shows up when you layer in financing: at 6.85% on a 20% down payment, the monthly mortgage is $925, and after adding estimated expenses of $451, the model spits out negative $89 in monthly cash flow and a cash-on-cash return of -2.63%. The cap rate tells you the asset earns; the debt service tells you the current rate environment is eating that margin. Year-over-year home prices are down 0.43%, so this is not an appreciation play either, scoring only 48 on that dimension. Saint Louis City is a market caught between a genuinely attractive price-to-rent relationship and a rate environment that punishes leveraged buyers.
That profile points to a specific type of buyer: the all-cash or low-leverage operator who can actually capture the 5.69% cap rate without a mortgage compressing it into negative territory, or a value-add investor who can push rents above the current $1,287 median. At $176,514 median purchase price, the absolute dollar exposure is low enough that all-cash deals are feasible for buyers with meaningful capital, and the cash-flow score of 88 out of 100 reflects what the unlevered picture looks like. Appreciation buyers should look elsewhere; a 48 appreciation score and a slightly declining price trend indicate this is not a market pricing in growth expectations. The stability score of 50 is a flag worth taking seriously, suggesting the market carries meaningful volatility or demand fragility that a purely passive buy-and-hold investor needs to price in.
The monthly tax and insurance burden comes to $207 on a median-priced property, with an estimated annual property tax of $1,712 and annual insurance of $777. Missouri's state-average effective rate is estimated at 0.97%, which falls into the normal range and is not in itself a deal-killer, though the honest caveat here is that this is a state-average figure and actual city or township rates in Saint Louis City can differ materially. That $207 monthly carry cost is already baked into the $451 estimated expense figure, so it is not an additional surprise, but investors underwriting specific deals should pull the actual assessed value and millage rate for each parcel rather than relying on the state average.
The stability score of 50 and the slight population context of 298,018 in an independent city with no surrounding county structure are the most meaningful risk flags the data supports. Saint Louis City is an independent city in Missouri, which means its tax base, school funding, and municipal services are entirely self-contained without the suburban county cushion most cities carry. Concentration risk is real: if rental demand softens in the city, there is no suburban fringe absorbing overflow. Investors who require a vacancy buffer or who are underwriting to high occupancy assumptions should stress-test their models against the stability score. No vacancy or crime statistics are in the provided data, and none are being added here.
Comparing Saint Louis City to its neighbor set sharpens the picture. Buchanan County shows a rent-to-price ratio of only 0.579%, well below Saint Louis City's 0.875%, meaning Saint Louis City delivers meaningfully better gross yield on a relative basis despite Buchanan's similar median home price of $182,875. Butler County at $160,556 median and a 0.673% rent-to-price ratio is cheaper to enter but still trails Saint Louis City on the rent yield metric. Jefferson County carries a median price of $281,743, nearly $100,000 more than Saint Louis City, and a rent-to-price ratio of 0.623%, making it a harder pencil on cash flow at higher basis. Clinton and Maries counties have no rent data provided, so yield comparisons cannot be made. On overall score, Saint Louis City ties Buchanan at 69 and sits one point below Clinton, Butler, and Maries at 70, and two points above Jefferson at 67, meaning none of these neighbors offer a dramatic scoring advantage.
Choose Saint Louis City over its neighbors when you are an all-cash buyer or a value-add operator who wants the highest gross rent yield in the set at the lowest price point, and when you have the operational infrastructure to manage an urban, independent-city market. Pass on it if you need conventional leverage to cash-flow at current rates, or if your strategy depends on price appreciation to generate returns, because neither condition is met here.
