Columbine Valley’s effective property tax rate climbed from 0.6% in 2017 to 0.7% in 2025, reflecting a 0.1 percentage point rise over nine years, BlockShopper.com reports.
The average effective property tax rate in Arapahoe County remained at 0.6% in 2025, unchanged compared with 2017. For 2025, Columbine Valley’s rate surpassed the county average.
Columbine Valley posted the fifth smallest effective property tax rate increase among 24 Arapahoe County cities reviewed during that period.
For 2025, the town ranked sixth among Arapahoe County cities for its current effective property tax rate of 0.7%.

According to Redfin, U.S. home prices continued rising in 2025, with the national median hitting about $447,000 in June, up 1.13% from a year prior. The data also indicate a notable gap in supply and demand, with 36% more sellers than buyers, or 508,715 homes. Redfin defines a balanced market as one where seller and buyer counts are within 10% of each other.
Even if property tax rates stay steady or drop, rising home values can lead to higher bills for homeowners. Tax bills are based on the tax rate and the assessed value, so increases in home prices can result in higher taxes even if rates decrease. From 2023 to 2024, the average effective property tax rate for a median-valued home in each state’s largest city fell by more than 5%, a Lincoln Institute of Land Policy analysis found.
Additionally, higher property values have boosted the overall tax base in many locations. Since property taxes are connected to changes in market value, increases in home values can generate larger tax bills even with declining rates. Research on the U.S. housing market has found that a 1% gain in median home value correlates with about a 0.71% drop in the effective tax rate, meaning governments can collect more even as the rate declines.
