The September 2026 real estate figures are officially in for Waukesha County, Wisconsin! As we head further into autumn, the local market is moving at an incredibly efficient pace. While sales volume and overall active inventory took a slight step back, buyers remain highly motivated to snap up what is available, and home values are holding strong. Whether you are aiming to buy, sell, or track your home’s equity, these figures are critical for your fall planning.
Here is a breakdown of the key metrics provided by Metro MLS RapidStats and what they reveal about the Waukesha County market today.
📉 A Slight Autumn Pullback in Inventory and Sales
Following typical seasonal patterns, the raw volume of homes moving onto and off the market dipped slightly compared to the busier summer months.
- Total Active Inventory (1,042): The total number of available properties on the market shrank slightly, dipping by -1.42% month-over-month.
- New Listings (560): Fresh listings entering the market also cooled down, dropping -6.51% M-O-M.
- Total Sales (454): Closed transactions fell by -15.61%, showing a standard seasonal deceleration in closing volume.
- Pending Contracts (140): Bucking the downward trend, the pipeline of homes entering escrow actually increased by +2.19%, demonstrating that strong buyer demand is keeping pace with new inventory.
💰 Pricing Trends: Closed Deals Dip vs. Record-High List Prices
September brought a unique dynamic where final closed prices eased slightly from summer highs, but incoming sellers are setting their sights significantly higher.
- Median Sales Price ($523,414): The median closed price dropped by -4.22% month-over-month.
- Average Sales Price ($597,219): The average price for closed sales shifted downward by -6.76% from August.
In stark contrast, fresh properties are demanding a major premium:
- Median New List Price ($534,950): The median price tag for fresh listings rose +3.87% M-O-M.
- Average New List Price ($652,607): The average price for newly listed inventory surged by an impressive +9.72%, indicating a notable influx of high-end luxury properties hitting the market.
⏱️ Days on Market & Inventory Supply
- Average Days on Market (19 Days): Homes are moving at lightning speed in Waukesha County. The average time on the market quickened, shaving 2 days off August’s timeline. Well-positioned homes are securing contracts in less than three weeks on average.
- Months of Supply (2.3 Months): Despite fewer listings, months of supply edged up slightly to 2.3 months (compared to 1.96 in August). Because a balanced market requires a 4-to-6-month supply, Waukesha County remains firmly entrenched in a highly competitive seller’s market.
💡 What This Means for You
- For Buyers: Closed sale prices dipped slightly this month, providing a tiny window of relief. However, because the average home sells in just 19 days and brand-new listings are coming to market with much higher price tags (average up nearly 10%), you need to have your pre-approval in hand and look at new homes immediately when they launch.
- For Sellers: The market velocity is entirely in your favor. With an exceptionally low 2.3-month supply and homes selling in under three weeks, you hold the upper hand. While luxury listings are driving up the average list price, ensuring your home is priced accurately against recent local closed sales will guarantee a fast, competitive sale.
