Top 20 Most Expensive ZIP Codes in Missouri Revealed

JEFFERSON CITY, Mo. — A recent analysis of real estate data has identified the 20 most expensive ZIP codes in Missouri, highlighting unique suburban communities with soaring home values.

The study, conducted using data from Zillow, illustrates the sharp increase in home prices across the state as of February 2025. At the forefront is ZIP code 63124, located in the St. Louis suburb of Ladue. This area has maintained its status as a wealthy neighborhood, with approximately half of its households earning $200,000 or more annually. The median household income in this ZIP code is reported at $188,750, climbing significantly higher to an average of $349,511.

According to the latest data, the median home value in 63124 has surged to approximately $1.155 million. This is a remarkable increase of 43.6% since February 2020, when the median stood at $804,799. “The growth in home values is a reflection of the desirability and affluence of the area,” said an expert familiar with the Missouri real estate market.

Following closely is ZIP code 63073, encompassing St. Albans, an unincorporated community adjacent to the Missouri River. This area, too, commands high income levels, with over half of its households earning $200,000 or more. The median household income here exceeds $250,000, while the average income is around $347,637. The growth in median home value from $653,961 in February 2020 to $907,541 in February 2025 marks a 38.8% increase.

Another notable entry is ZIP code 63131, which includes neighborhoods like Des Peres, Huntleigh, and Town and Country, situated to the west of St. Louis. Similar to its counterparts, more than half of the households earn $200,000 or more, with the median household income reported at $209,306. The average household income is $335,161, and home values have risen by 42.4% over the past five years, reaching $882,115.

The analysis suggests that while market conditions continue to fluctuate, home values in Missouri’s affluent areas show no sign of decline. The real estate market’s performance in these ZIP codes implies a continued demand for high-end real estate, despite rising mortgage rates, which have reached an average of 6.67% as of March 2025. “High-income earners are insulated from the impact of market volatility, often continuing to invest in real estate,” said a local economist.

The data underscores the trend of urban sprawl, as affluent buyers increasingly seek homeownership opportunities in suburban locations, offering a blend of tranquility and accessibility to urban amenities.
