The Boulder County housing market in May 2026
Prices in Boulder County held steady at a median of $750,000 in May 2026, within 0.1% of a year earlier. Homes listed that month had a median asking price of $750,000, and sold for a median of $369 per square foot. The average sale closed at 99.2% of asking price, and 24% of homes sold above list.
There were 1,515 homes for sale at the end of May, down 14% from a year earlier, or 3.5 months of supply, still on the sellers' side. The typical home that sold had been listed for 42 days, 4 days less than a year earlier. 38% of homes went under contract within two weeks of listing. Compared with May 2025, owners listed 20% fewer homes and sales were down 7%.
Price cuts are common: 31% of listings were reduced in May 2026 (2.0 points more than a year earlier). An FSBO owner who has not cut yet may be priced above the market.
For FSBO outreach, this means owners who price well still sell on their own, while those who overprice start to sit, and they are the ones most open to help. The trend to watch: fewer homes for sale than a year ago.
How Boulder County compares with other Colorado counties
Boulder County against the other 7 Colorado counties profiled on this site, using Redfin's May 2026 figures. El Paso County is left out because Redfin publishes no sales figures for it.

- Median days on market: 42 days, 3rd-slowest of 8, between Weld County (50 days) and Adams County (24 days).

Boulder County since 2019
The median sale price averaged about $742,000 from March to May 2026, up 39% from about $534,000 in the same months of 2019.
Prices peaked at about $788,000 (three-month average) in the three months to June 2022 and are now about 6% below that high. Owners who bought near the peak may have little equity, which leaves them less room to cut their price.
There are more homes for sale than before the pandemic: about 1,450 in an average month in spring 2026, against 1,150 in spring 2019, 26% more.
In spring 2026 the median time on market averaged about 46 days, 13 days longer than in spring 2019 (32 days).
Owners are listing about 9% fewer homes a month than they did in spring 2019.
For FSBO outreach, that means more Boulder County owners are competing for buyers than before the pandemic, and more of them are likely to need help.
When Boulder County homeowners list
Listing activity is strongly seasonal in Boulder County. Over the three years to May 2026, new listings peaked in April and May, with April running about 49% above the monthly average, and bottomed out in December, about 68% below it. Homes that sold in June had spent the least time on the market (a median of about 41 days), and those that sold in January the most (about 87 days).
Have your list, scripts and mail pieces ready by March, so you reach new FSBO owners in their first weeks. Sales are slowest around January, so FSBO owners still on the market then have often been waiting for months and tend to be the most open to help.

Working Boulder County FSBO leads
- Time it. Put your heaviest outreach into April and May, when the most Boulder County homes come to market, and ease off in December.
- Split the list by city. Louisville (median $1,065,500) and Longmont (median $558,250) sit 91% apart on price, and Longmont also had the most sales in May 2026 (135), so one script will not fit every owner.
- Bring the numbers. On a $750,000 home, each 1% of commission is about $7,500, the money most FSBO owners are trying to keep, so a net-sheet comparison lands better than a pitch.
- Follow the price cuts. When 31% of listings are being reduced, an FSBO owner who cuts is showing motivation; follow up soon after any change in the asking price.
- Stay compliant and verify. Stop contacting any owner who says "no agents" or "no investors", confirm ownership and liens in Boulder County records before an offer, and add skip tracing for records without a phone number.
