Local rules to check before you underwrite
St. Louis requires a short-term rental permit and an occupancy permit with a Housing Conservation inspection that sets the occupancy load. An occupied rental, meaning your principal residence, needs one permit, while a non-occupied rental needs the permit plus a city business license. A residential occupancy permit is valid for 12 months, and rental units generally need reinspection every three years or when occupancy changes.
Local rules checked October 2026 against: St. Louis short-term rental permits, St. Louis code Chapter 25.57. Rules change, so confirm with the city before you rely on them.
Costs that move the St. Louis ratio

Median household income of $56,160 (about 21% below the Missouri median of $70,702) sets the ceiling for rent growth, and 46% of renters already spend 30 percent or more of income on rent.
The kind of housing in St. Louis
Multifamily matters in St. Louis. About 52% of housing units are in multi-unit buildings, and 26% are in two to four unit properties that fit standard DSCR programs. Housing here skews old (median year built 1938), so condition and the age of major systems matter as much as the rent.
Use vacancy as a reality check: 17% of all units are vacant in St. Louis, and the rental vacancy rate is 7.7%.
How investors should read St. Louis
At 6.1% gross, St. Louis is a middle-yield market, so ratios usually clear with a normal down payment and careful attention to insurance and taxes. Older homes dominate St. Louis, so ask about roof, panel and plumbing age early, because insurers and appraisers do. A large renter population (55%) supports leasing, though it also means many competing landlords, so condition and price positioning count.

Running the numbers in St. Louis
Try the math at the medians. With rent at $997 and taxes near $169 a month, a 1.00 DSCR leaves $828 for everything else in the payment, a 1.20 ratio leaves $661, and a 1.25 ratio leaves $628. Any real property will differ, but the exercise shows how little room insurance and dues can take.
What MO law and St. Louis require of landlords
If you are weighing nightly income in St. Louis, the state tax backdrop is this. Missouri treats nightly vacation rental charges, including cleaning and service fees, as taxable sales, exempts stays of 31 or more consecutive days, and requires marketplace facilitators to collect, while local lodging and tourism taxes remain the owner's job unless the platform handles them.
After move-out, the St. Louis owner has 30 days to return the deposit or account for deductions. Expect to give Written notice; tenancy ends on a rent-paying date at least one month after the tenant receives it of notice to end a month-to-month arrangement at a St. Louis rental. As to caps on rent in St. Louis: Cities and counties may not enact or enforce rent control ordinances (with narrow exceptions for subsidized/public property).
