St. Louis, Missouri, has quietly maintained a remarkable advantage in housing affordability for more than 134 years, with inflation-adjusted house prices rising only six percent since 1890. This stands in stark contrast to national trends, where average home prices have climbed 354 percent over the same period, and cities like San Diego and Los Angeles have seen increases exceeding 1,000 percent.

New research by the Federal Reserve Bank of Philadelphia, which involved manually collecting 2.7 million real estate listings dating back to 1890, highlighted St. Louis's exceptional stability. The study examined for-sale listings from the St. Louis Post-Dispatch between 1890 and 2006 to build one of the longest historical housing price records assembled.

Factors Behind St. Louis's Affordability

Real estate professionals attribute St. Louis's long-term affordability to a combination of factors, primarily sufficient land for new construction and relatively subdued population growth. "St. Louis and the surrounding county have historically had enough land to build more homes when demand increased," said Sam Hall, co-founder of the Warner Hall Group and president-elect of St. Louis Realtors. This contrasts with many coastal markets where development is limited by geography and stricter zoning.

Kathy Helbig, a St. Louis real estate agent with 30 years of experience, noted that the city has never experienced the intense competition for housing seen elsewhere. "We never ran out of land. Our population hasn't really spiked. We've never not been an affordable city - ever," she stated.

Historical Context and National Comparison

St. Louis, often referred to as the 'forgotten city' due to a population decline of over 60 percent since its 1950 peak as residents moved to suburbs, entered the post-World War II era with a substantial housing stock. Researchers from the Federal Reserve found that many Rust Belt cities, like St. Louis, built extensively in the 1920s and entered the mid-20th century with ample housing capacity.

Conversely, cities like Los Angeles and San Francisco struggled to match housing construction with rapidly growing populations. Barriers to development and restrictive zoning in these areas contributed to significant price escalations.

Current Market Snapshot

Today, nearly 60 percent of homes for sale in St. Louis are considered affordable, according to a recent Zillow analysis, placing it second only to Buffalo, New York, among examined cities. The median home price in St. Louis County was approximately $313,000 in late July, with properties spending about 25 days on the market. Within the City of St. Louis, the median sale price was lower, around $240,000, with homes taking approximately 35 days to sell. This is considerably lower than the national median existing-home sale price of around $434,000 in July.

While expensive properties exist in affluent suburbs, they remain the exception. The modest gap between renting and owning also contributes to St. Louis's appeal. The median rent was around $1,200 in January, while a median-priced home purchase could result in a monthly mortgage payment of roughly $1,500, facilitating the conversion of renters into buyers.

The Trade-off of Affordability

Despite the significant advantages, St. Louis's housing affordability comes with a trade-off: limited property value appreciation. Homeowners in St. Louis have not experienced the substantial increases in wealth seen in booming markets like Los Angeles or San Diego. This is linked to the slower population growth and weaker economic base compared to coastal cities.

Furthermore, recent years have seen affordability challenged by rising mortgage rates and home prices. In May 2019, a household earning around $66,000 could afford a median-priced $185,000 home with a 4.1 percent mortgage rate. By May 2026, with median household income at $85,000, rising mortgage rates to approximately 6.4 percent and a median home price of $257,000 pushed monthly housing costs to around $2,100.

Homeowners also face increased insurance costs due to the city's location in Tornado Alley. The average St. Louis homeowner pays approximately $2,619 annually for home insurance. Nevertheless, the city's overall cost of living remains a major attraction, allowing residents to own homes in ways that would be impossible in many other parts of the country.
