St. Louis luxury home sales in six key ZIP codes have already surpassed last year’s full-year total. From January 1 through November 11, 2026, MARIS recorded 483 residential sales at $1 million or above across 63124, 63105, 63131, 63141, 63017 and 63005—compared with 479 during all of 2025. The average sale price is approximately $1.87 million, while average cumulative days on market remains at 39 days.
For homeowners considering a sale and buyers planning their next move, these results demonstrate substantial transaction activity in this segment of the St. Louis market. Understanding what they mean for a particular property requires a closer look at location, condition, price range and competing homes.
For this update, luxury is defined as residential properties selling for $1 million or more within the six selected ZIP codes.
Market measure | Full-year 2025: Jan. 1–Dec. 31 | 2026 to date: Jan. 1–Nov. 11 |
|---|---|---|
Closed residential sales | 479 | 483 |
Median sale price | $1,560,000 | $1,525,000 |
Average sale price | $1,846,009 | $1,874,656 |
Average cumulative days on market | 39 days | 39 days |
Highest sale price | $7,750,000 | $7,500,000 |
Source: MARIS closed-sale reports prepared November 11, 2026. The reporting periods differ: 2026 figures are year to date, while 2025 figures cover the entire calendar year. These are combined results for the six ZIP codes, rather than individual ZIP-code statistics.
Luxury sales have already exceeded the previous full year. With 483 residential closings through November 11, the selected market has recorded four more qualifying sales than it did during all of 2025. That is a meaningful measure of activity, although an exact year-over-year growth rate requires matching dates in both years.
Prices tell a more nuanced story. The 2026 average sale price is approximately 1.6% higher than the full-year 2025 average, while the median is approximately 2.2% lower. The median is the midpoint of the sales; the average is more sensitive to exceptionally high-priced transactions.
These results can reflect changes in the mix of properties sold. They do not establish that an individual home has appreciated or declined by either percentage.
Average cumulative market time is unchanged at 39 days. This is an average for properties that closed, rather than a promise about how quickly a new listing will sell. It also does not describe the experience of homes still on the market. Sellers should use it as context alongside recent comparable sales and current competition.
The MARIS reports combine all six ZIP codes. The following guidance explains how I approach properties in these areas; it does not imply that every ZIP experienced the same sales trend. ZIP codes can cross municipal and school-district boundaries.
For a luxury home in the Ladue area, acreage, setting, architectural character, renovations and new-construction alternatives all deserve careful consideration.
An older estate requiring extensive work should be evaluated differently from a recently renovated home or a newly built residence. My recommendation is to start with the most comparable properties and identify the features that support your home’s position in the market.
In the Clayton area, single-family homes and luxury condominiums need separate analyses.
For a condominium, I examine the building, floor, views, outdoor space, parking, amenities and association expenses. For a detached home, the lot, layout, condition and location guide the comparison. A combined market average cannot capture those differences.
For properties in and around these communities, lot characteristics, improvements and the surrounding competition are central to pricing.
A buyer comparing a renovated home with new construction may weigh immediate convenience against the ability to select finishes and customize a floor plan. Sellers benefit from understanding those alternatives before choosing an asking price.
For a luxury property in the Creve Coeur area, I recommend narrowing the comparison to homes with similar lots, living space, condition and features.
The value of an extensively updated home may differ substantially from that of a property needing major improvements. A focused analysis helps buyers and sellers understand the reasons behind those differences.
For a Chesterfield-area home with acreage, a pool or extensive outdoor living space, the most useful comparisons may extend beyond the immediate subdivision.
My approach is to evaluate both the house and the setting, including privacy, layout, maintenance and the usefulness of outdoor amenities. Marketing should make those distinctions easy for buyers to understand.
For larger custom homes and estate properties, size alone does not determine value. Construction quality, renovations, floor-plan functionality, grounds and ongoing care all matter.
I recommend comparing the property with current alternatives as well as recent sales. That helps sellers support their asking price and buyers assess what a particular home offers.
The number of completed transactions is encouraging for homeowners considering a sale. The next step is to determine how your property fits within its specific market.
My recommendations are to:
If you are considering selling in spring 2027, planning now gives you time to prioritize improvements, arrange contractors and develop a marketing schedule suited to your home.
The combined sales figures show that buyers are completing purchases throughout this million-dollar-plus market. Your offer strategy should still depend on the particular property.
Review comparable sales, competing listings, condition and potential renovation costs before deciding what to offer. For an estate, include the grounds, pool and other improvements in your assessment. For a luxury condominium, review association documents, expenses and building-specific considerations.
A home that closely meets your needs may call for a different approach from one requiring substantial work or carrying an ambitious asking price.

Data and methodology: Based on the Residential closed-sale sections of two MARIS CMA reports prepared November 11, 2026, covering ZIP codes 63124, 63105, 63131, 63141, 63017 and 63005 and sale prices of $1 million or more. The 2026 report covers January 1 through the report date; the comparison report covers January 1–December 31, 2025. Residential income, separately classified land and lots, farm and commercial transactions are excluded. Figures describe the reported closed-sale sample, not active inventory or the entire St. Louis metropolitan area. Percentage comparisons use rounded report averages and medians.
