Who Rents In St. Louis And Why They Stay

St. Louis is a renters' city. Of its households, 54.7% rent, against 31.9% across Missouri, for a total of 79,279 renter households (U.S. Census ACS 2020–2024). Median gross rent in St. Louis is $997 a month, up 20.4% from $828 in the 2015–2019 survey, while median household income rose 27.9% to $56,160. Pay has outrun rent here, which is unusual among the markets we track. The harder numbers are on headcount. Population fell 6.4% over the same five years, renter households slipped 0.9%, and 45.7% of renters spend 30% or more of their income on housing.

Healthcare and universities do most of the work in the city itself. Washington University in St. Louis reported 23,434 employees in fiscal 2025 and calls itself the region's second-largest employer. Its physicians staff BJC HealthCare's Barnes-Jewish and St. Louis Children's hospitals and the Siteman Cancer Center on the medical campus at the edge of the Central West End. Saint Louis University and Harris-Stowe State University add students and staff, and the city government is a large payroll of its own. The biggest recent change came on the north side: the National Geospatial-Intelligence Agency opened its $1.75 billion Next NGA West campus in St. Louis Place in September 2025, the largest federal investment in the city's history. About 3,100 workers were expected to finish moving there from the old Soulard site by spring 2026.

For owners, this means demand is concentrated rather than broad. Buildings within reach of the medical campus, the universities and the NGA have a clear tenant base. Elsewhere, a shrinking population sets a ceiling on how fast rents can climb. Anyone weighing apartment syndications in St. Louis should look at the specific blocks, not the citywide average.

Supply, Rents And Occupancy In St. Louis Right Now

The St. Louis metro is past its construction peak. Northmarq reported in March 2026 that about 2,400 units were delivered in 2025, down 13% from 2024 and 50% below the 2022 peak, and it expected 2026 to be one of the slowest construction years in a decade. Rents for middle- and lower-tier properties rose nearly 3.0% in 2025, and net move-ins ran 7% above the five-year average. Multi-Housing News, using Yardi Matrix data, put metro asking rent at $1,344 in March 2026, up 0.3% over three months, with occupancy at 93.4%, below the national 94.3%. About 4,700 units were under construction and roughly 21,000 more sat in planning.

Inside the city, the Census shows an old, apartment-heavy stock. There are 44,734 homes in buildings with five or more units, 25.7% of all housing, and that count grew only 4.1% in five years. The median home was built in 1938. Rental vacancy is 7.7% on the Census measure, which counts every rental, including the many two-family flats and single-family houses that make up much of South City, so it isn't directly comparable to broker occupancy for managed communities.

A buyer here is usually buying an older building, often near 100 years old, with deferred capital needs to price in. Light new supply helps existing owners, but the main risks are property condition, insurance and the block-by-block quality of the location. We'd rather underwrite flat population and real repair costs than count on a turnaround story.

How St. Louis Ranks For Apartment Investors

Out of 29 Missouri cities in our data, St. Louis comes in 24th for median gross rent, 2nd for renter share and 26th for five-year rent growth. Its rents sit near the bottom of the group, which keeps it affordable for tenants but also caps what renovations can earn. In raw numbers, St. Louis has about 19,662 fewer residents, 720 fewer renter households and 1,762 more homes in buildings with 5 or more units than in the 2015–2019 survey. With fewer renter households than before, a building has to win tenants from competitors rather than from new demand.

St. Louis Compared With Missouri

St. Louis's median gross rent of $997 is below the Missouri median of $1,033, and its renter share is 54.7% compared with 31.9% statewide.

St. Louis Rent Affordability In Dollars

The median rent in St. Louis works out to $11,964 a year, about 21.3% of the median household income of $56,160. Under the common 30% guideline, a household needs about $39,900 a year to cover that rent comfortably. That's a heavier load than the Missouri average of 17.5%. Renters usually earn less than the all-household median, so the real burden for tenants is higher than this simple ratio shows.

Since the 2015–2019 survey, the median rent rose $169 a month ($2,028 a year), while median household income rose $12,251 a year. Income has outpaced rent, which means tenants have a bit more room in their budgets than they did five years ago.

What We Look For In A St. Louis Apartment Building

Skyline buys 5+ unit apartment buildings in St. Louis that either run well today or can run better with new management or renovation. We start with rents, occupancy and the condition of the building, and we price on what the property earns now.

Property taxes are a big line item for any Missouri apartment building. We underwrite the tax bill after purchase, not the seller's current bill, since a sale often resets the assessment. Missouri has no statewide rent control law, though local rules on notices, fees and deposits still apply. Insurance quotes in Missouri reflect hail and wind damage, so we get a quote before we make an offer.

With vacancy on the high side, we budget for longer lease-ups and look for buildings whose occupancy is already above the market average.

Questions To Ask About An Apartment Syndication In St. Louis

Whoever the sponsor is, these are the questions we would want answered about any apartment syndication in St. Louis, based on the local numbers above.

• What vacancy does the plan assume? Rental vacancy in St. Louis is 7.7%. A plan that assumes much lower vacancy than the market should explain why.
• What rent growth is underwritten? Rents here rose 20.4% over five years. Ask whether the plan assumes that pace continues, and what happens to the deal if rents stay flat.
• How was the property tax bill estimated? A sale often triggers a reassessment, so the bill after purchase can be well above what the seller pays today.
• What capital work is budgeted? The median home in St. Louis was built in 1938, so roofs, plumbing and electrical systems deserve their own line items.
• How will the building hold occupancy? Renter households in St. Louis fell 0.9%, so the plan should show how it keeps units full.
• How and when does capital come back? Ask what the plan is for a refinance or sale, and what happens if that takes longer than expected.

How Passive Investing In A St. Louis Apartment Syndication Works

In an apartment syndication, Skyline acts as the general partner. We find the St. Louis property, negotiate the purchase, arrange the loan and oversee management and any renovation. Limited partners put in capital and own a share of the entity that owns the building. They don't sign on the loan or deal with tenants and repairs.

Expect your money to be tied up for years, with no easy way to sell your share early, and remember that any investment can lose money. Most deals are open only to accredited investors under Rule 506(b) or 506(c). See investing with Skyline Capital for how we work with limited partners.
