July sorted the Front Range into two camps. Denver, Boulder, and Longmont all saw median sold prices fall. The Castle Rock housing market July 2026 report went the other way, with the median sold price up 7.46%. It is also the market where sellers brought the most new inventory, which makes for an unusual combination worth unpacking.
The Big Picture
Castle Rock sits in seller’s market territory with 4.12 months of inventory, up 9.57% from the previous month. Homes sold for 98.5% of list price, essentially unchanged, and the median sold price came in at $735,000, up 7.46%.
Prices Rose, But Look at What Sold
Before treating that 7.46% as pure appreciation, look at the volume. Only 143 homes sold, down 23.1% from June, generating $135.7M in total volume, down 13.5%. And median sold price per square foot actually fell 3.6% to $266.
A higher median price alongside a lower price per square foot points to one conclusion: bigger homes closed in July. Castle Rock’s sold public records show a median living area of 3,224 square feet, up 17.3% month over month. When the mix shifts toward larger properties, the median sale price rises even if per-square-foot values soften slightly.
The broader valuation picture confirms the more moderate read. The median estimated property value across Castle Rock is $684,740, down 0.2% for the month and 1.7% over the past 12 months. Values are drifting gently lower even as July’s closings skewed expensive.
Inventory Is Building Faster Here Than Anywhere Else
Months supply of inventory sits at 4.12, up 9.57% month over month, which is the largest monthly inventory increase among the Front Range markets in this report. Year over year, supply is down 10%.
The listing side explains it. Active listings rose 8.8% to 643 properties at a median list price of $729K, down 1.5%, sitting a median of 54 days at $276 per square foot. New listings rose 9.4% to 255 properties at a median list price of $680K, down 4.2%. Sellers are coming to market in growing numbers, and they are doing it at slightly lower asking prices than the month before.
Speed to Sale
The median time a home spent in RPR (Realtors Property Resource) before selling was 43 days, up 30.3% from the prior month. That is the slowest pace among Denver at 26 days, Longmont at 32, Boulder at 41, and Castle Rock this month.
That is a function of both price point and property size. Castle Rock’s inventory skews toward larger single-family homes at a median 2,950 square feet on active listings, a segment with a naturally smaller and more deliberate buyer pool. Forty-three days is normal for that product, but it is a real planning consideration if you are listing.
New and Pending Activity
New pending listings rose 4.1% to 151 properties at a median list price of $714.9K, with a median of 44 days in RPR. Pending listings overall numbered 165, down 1.2%, at a median list price of $725K and 41 median days. Unlike Denver, Boulder, and Longmont, where pending counts fell sharply, Castle Rock’s contract pipeline held roughly steady.
Sold Homes
143 homes sold in July at a median price of $735K and a sold-to-list ratio of 98.55%, essentially flat month over month. Rising inventory has not translated into deep discounting: buyers are negotiating about a percent and a half off asking, the same as in June.
What This Means for Buyers and Sellers
Sellers have more competition than last month. With 643 active listings, up 8.8%, and 255 new listings, up 9.4%, your home is entering a fuller field. Price to the current market rather than to July’s $735K median, which was pushed up by larger homes closing; median sold price per square foot was $266, down 3.6%, and that is the more useful benchmark. Plan for 43 days or more, the slowest of the four Front Range markets, and build that into any contingent purchase timeline. The 98.55% sold-to-list ratio still favors you when pricing is accurate.
Buyers have the best selection on the Front Range right now. Castle Rock is the only market in this report where both active and new listings grew. Space per dollar is exceptional at $266 per square foot on sold homes and $276 on active listings, with a median active living area of 2,950 square feet, substantially more house per dollar than Boulder at $585 per square foot or Denver at $384. Use the 43-day timeline to inspect thoroughly and negotiate repairs without rushing.
As always, conditions vary by subdivision, home size, and whether you are looking at resale or new construction, so working with an agent familiar with the specific submarket remains valuable.
