St Louis County home sellers saw a median sale price of $315,000 in September 2026, up 6.78 percent from $295,000 in September 2025, according to the latest data. While this year-over-year growth is significant, the median price also reflects a 3.08 percent drop from August 2026, when the median reached $325,000. The chart below, available exclusively from MORE, REALTORS®, provides a visual breakdown of these changes and more.
What the Numbers Mean for Buyers and Sellers
For sellers, the 6.78 percent annual gain in median sale price is a clear sign that St Louis County continues to deliver strong returns compared to last year. However, the month-to-month dip from August to September indicates some cooling in the market, a trend sellers should keep in mind when pricing their homes or considering timing.
Buyers will notice a striking shift in asking prices. The median asking price for homes on the market is now $239,900, down 18.12 percent from $293,000 in September 2025. This drop in listed prices may present more opportunities for buyers, especially those who were previously priced out. However, with the current 30 year fixed mortgage rate at 7.37 percent, affordability remains a challenge despite the lower asking prices.
Market Dynamics: Supply, Demand, and Timing
Inventory has grown, with 4,392 homes currently on the market in St Louis County. Over the past twelve months, 13,082 homes have sold, and September 2026 saw 1,092 home sales, a slight decrease of 2.76 percent from 1,123 in September 2025. This dip in sales volume, combined with the increase in active listings, suggests a market that is shifting toward balance.
The months of supply metric currently sits at 4.02. Generally, a market with under four months of supply is considered to favor sellers, while over six months leans toward buyers. At just over four months, St Louis County is in a transitional phase. Sellers still have the advantage, but buyers are gaining leverage as inventory increases and homes take longer to sell.
The median days on market is now 53 days. This means it is taking longer for homes to go under contract compared to the rapid sales pace seen in hotter markets. For sellers, patience is more important than ever, and strategic pricing is crucial. For buyers, the longer market time can mean more negotiation room and less pressure to make immediate decisions.
Key Takeaways for Agents and Consumers
For real estate agents, these dynamics require a nuanced approach. Sellers need guidance on setting realistic prices in light of the drop in asking prices and increased competition. Buyers need help navigating higher mortgage rates and identifying value as more inventory becomes available. Agents who focus on clear communication, accurate pricing strategies, and strong negotiation skills will serve both their clients and their business well in this evolving market.
For consumers, the current environment means carefully weighing the pros and cons. Sellers can still capture gains over last year, but should not expect the rapid price growth or quick sales of previous months. Buyers will find more options and less competition at the offer table, but must be mindful of higher borrowing costs. The chart below, available exclusively from MORE, REALTORS®, offers additional insights into these trends and can help both buyers and sellers make informed decisions.
