The Boulder housing market August 2026 report is a study in contradictions. Inventory tightened again and is now down more than a third from a year ago. The median sold price fell over 11%. And buyers under contract are paying list prices more than 20% higher than they were in July. All three things are true at once.
The Big Picture
Boulder sits in seller’s market territory with 4.95 months of inventory, down 7.99% from the previous month. Homes sold for 97.2% of list price, down 0.61%, and the median sold price came in at $870,000 — down 11.22%.
Inventory Is Down 34.3% Year Over Year
Months supply of inventory fell 8% month over month and is down 34.3% compared to twelve months ago. Boulder’s supply has been contracting steadily all year, and August continued the trend.
Active listings fell 9.4% to 658 properties, with total active dollar volume down 9.2% to $1.09B. New listings dropped 10.5% to 214 properties. Fewer sellers came to market, and the existing pool kept thinning.
Speed to Sale
The median time a home spent in RPR (Realtors Property Resource) before selling was 44 days, up 4.76% from the prior month. Active listings are sitting a median of 68 days, up 1.5%.
Forty-four days remains the longest sale timeline among the Front Range markets in this report, which is what a market with a near-million-dollar median looks like. The buyer pool at that price point is smaller and more deliberate by nature.
The Pending Signal
Here is the most interesting number in Boulder’s August report. New pending listings rose 4.5% to 117 properties — but at a median list price of $1.15M, up 22.1% month over month. Total new pending volume jumped 25.8% to $162M, and median $/sqft on new pendings rose 9.4% to $559.
Pending listings overall tell the same story: 135 properties, up 4.7%, at a median list price of $1.15M, up 21.2%, with median $/sqft up 11.6% to $550.
Pending listings are homes already under contract but not yet closed, which makes them an early read on where sold prices are headed. Buyers going under contract in August committed to substantially higher prices than those who closed in August. That is a strong hint the median sold price dip is about which homes happened to close, not about Boulder values resetting.
Active Inventory
Active listings carried a median list price of $1.01M, up 1.1%, sitting a median of 68 days at $573 per square foot, with median living area of 1,877 square feet, up 5.5%.
Sold Homes
101 homes sold in August, down 24.1%, at a median price of $870K and a sold-to-list ratio of 97.21%. Total sold volume reached $127.3M, down 27.4%, with median sold price per square foot at $526, down 0.9%.
Just 101 closings is a thin month. When sales volume is that low, a handful of transactions can swing the median meaningfully — which is exactly why the pending figures above matter more than usual this month.
Property Values Are Still Up Year Over Year
The median estimated property value across Boulder came in at $985,220, down 0.4% month over month but up 1.1% over the past 12 months. Boulder remains the only market in this month’s report with a positive twelve-month value change.
What This Means for Buyers and Sellers
For sellers, scarcity continues to work in your favor. With inventory down 34.3% year over year and only 658 active listings, a well-prepared home faces less direct competition than at any point in the past year. Do not read the 11.22% median sold price drop as a value loss across the board — median estimated value is up 1.1% year over year, and buyers under contract are paying more, not less. Budget six weeks or more from list to contract, and hold your pricing: the 97.21% sold-to-list ratio means Boulder buyers negotiate, but only by a few percent.
For buyers, the window may be narrowing. Time on market is generous at 44 days, but inventory is down almost 10% in a single month and pending prices are climbing sharply. If you are waiting for Boulder to soften further, the contract data is pointing the other way. Watch the spread between the $573 per square foot median on active listings and $526 on sold homes — that gap is your negotiating context.
As always, conditions vary significantly by neighborhood and price point. A condo near Pearl Street and a single-family home in Table Mesa are effectively different markets, so working with an agent familiar with the specific submarket remains valuable.
