Real Estate Update - Castle Pines, CO Original Communities - June 2026
Neighborhoods Built Prior to 2015 (All Neighborhoods West of I-25 Except For Castle Valley and Skyline Ridge)
More higher-priced custom homes are selling in the Castle Pines, CO Original Communities this year, which has driven up the year to date average home price compared to 2025. During the first half of 2026, seven homes sold for more than $2 million—the same number that sold during all of 2025. Because Castle Pines has a relatively small number of annual sales, just a few large custom-home transactions can significantly influence the monthly average price.
For that reason, 12-month rolling averages provide a more reliable picture of the market. The average sales price for the 12 months ending in June was $1,098,978, up just 0.5% from $1,093,337 during the previous 12-month period. Meanwhile, the average price per square foot declined slightly from $235 to $234, a decrease of 0.7%. Together, these figures indicate that Castle Pines home values are generally flat, with some segments of the market experiencing modest downward pressure.
Inventory also remains relatively low compared with the rest of metro Denver. At the end of June, 39 homes were available for sale in the Original Communities. That was only 12% above the seven-year June average of 35 homes. By comparison, inventory throughout metro Denver was 44% above its seven-year June average.
Buyer activity has remained fairly consistent. A total of 140 homes sold during the 12 months ending in June, compared with 147 sales during the previous year. At the same time, fewer homeowners are putting their properties on the market. Only 22 homes were listed for sale in June, which was 21% below the seven-year June average of 28 new listings. Many homeowners continue to stay in place because they do not want to give up the low mortgage rates they secured in previous years.
Months of inventory, an important measure of supply and demand, stood at 2.6 months in June. A four- to five-month supply is generally considered a balanced market, while inventory below four months typically supports stable or rising prices. Although a 2.6-month supply would normally create conditions for modest appreciation, I do not expect Castle Pines prices to increase significantly this year. Higher mortgage rates, affordability challenges and softer conditions across the broader metro Denver market will likely keep prices flat or slightly lower through the remainder of 2026.
