St. Louis Had a 134-Year Affordability Streak
A recent MarketWatch analysis identified St. Louis as a rare long-term outlier in U.S. housing affordability.
The city has been described as one of the most affordable places for homebuying for more than 134 years.
That durability stood out because inflation-adjusted home prices rose only about 6% over the period.
Among the cities reviewed, St. Louis showed the smallest increase in relative home prices.
This 6% rise over 134 years was the core finding highlighted in the MarketWatch piece.
Structural Stability Under Pressure
Local reporting tied that resilience to a relatively ample housing supply and stalled population growth.
Those conditions reduced price pressure and helped preserve access even through economic shocks.
By contrast, Cleveland’s downtown distress shows how rising vacancy rates can undermine urban housing stability.
The broader market structure suggests affordability has been a durable feature rather than a temporary dip.
Historic demographics also matter.
With enough land for additional housing, St. Louis and its county retained flexibility when demand changed.
How Researchers Measured the Housing Streak
At the center of the method was a simple but demanding comparison: whether home-price growth stayed in line with, or below, income growth over long periods.
Researchers treated affordability as a relationship, not a sticker price.
Their income comparison focused on cumulative home-value growth against cumulative median-income growth.
Unlike sectors strained by dividend cuts, this framework centered on whether housing costs remained sustainable relative to earnings.
Building the Data
The measurement methods relied on repeat-sales style analysis to limit distortions from changing mixes of homes sold.
Researchers also built annual rent and sale-price series from historical newspaper listings, including the St. Louis Post-Dispatch.
Nearly 2.7 million listings were gathered by hand across decades.
Defining Affordability
A standard 30 percent threshold anchored the framework.
For renters, housing and utility costs had to stay below 30 percent of income.
For owners, mortgage, taxes, insurance, and utilities were included.
How Little St. Louis Home Prices Changed
Measured against the income-based yardstick behind the affordability streak, St. Louis home prices changed less dramatically than many large markets.
City measures still showed gains. Over the three months ending June 2026, the median sale price reached about $265,000, up 6.9 percent.
Another report put June at $310,000, up 5.1 percent, or $15,000. Price per square foot rose to about $170.
Uneven Signals Across Segments
The broader metro showed mixed signals. Its median listing price was $290,000 in June, down 3.3 percent from a year earlier.
Zillow’s typical metro value rose 2.9 percent to $276,878. Within the city, Zillow’s average value was $188,569, down 0.4 percent.
These differences reflected neighborhood dynamics, buyer demographics, and varying data methods rather than a single sharp market surge.
Why St. Louis Stayed Affordable
St. Louis remained affordable because housing demand rarely outran supply. Postwar housing stock was already ample, which helped limit scarcity-driven price pressure.
Population growth often stalled, so buyer competition stayed relatively muted across housing cycles. That kept bidding wars less intense than in faster-growing metros.
Land abundance in both the city and county also helped. Builders could add homes without concentrating pressure in a tight urban core.
| Factor | Effect |
|---|---|
| Long-term housing supply | Reduced shortage pressure |
| Slower population growth | Limited bidding wars |
| Land abundance | Lowered scarcity premiums |
| Regulatory leniency | Eased expansion |
Regulatory leniency further reduced cost inflation. Lighter planning constraints and fewer barriers to outward development helped the metro avoid permit bottlenecks and artificially high land costs.
Regional fragmentation also played a role. Uneven schools, disinvestment, and neighborhood differences spread demand unevenly and kept prices from rising uniformly across the metro.
How Affordable St. Louis Is Today
Even now, St. Louis remains strikingly affordable by major-metro standards.
Median home prices sit near $202,250 to $204,750, with values around $144 to $146 per square foot.
Sale prices have risen about 5% year over year, yet inventory of roughly 2,555 listings still leaves many options.
Rent and Household Strain
Median rent runs about $1,250 to $1,300 a month, while many one-bedroom units range from roughly $866 to $1,100.
Two-bedroom rents commonly fall between $1,109 and $1,375, supporting affordability despite uneven job growth.
A typical household needs about $64,348 to buy, versus median income near $88,931.
Cost Burden Signals
Housing payments take about 21.7% of income, and 71% of listings remain affordable to median earners.
A cost-of-living index of 95 and practical transit access reinforce the city’s lower-cost position.
Assessment
St. Louis sustained an extraordinary 134-year run of relative housing affordability. It remains a rarity in U.S. urban real estate history.
Researchers linked that streak to slow price growth, abundant housing stock, and decades of weaker demand than in faster-growing metros.
That long stability now faces mounting pressure from modern market shifts. Higher borrowing costs and tightening supply are adding to the strain.
Even so, St. Louis remains more affordable than many major U.S. cities. But that advantage appears increasingly vulnerable.
