Prepared for: 7415 Stagecoach Blvd, Castle Rock, CO 80108 · Douglas County, Colorado · Tax Year 2026
Market value was determined using two approaches: (1) Median $/SF analysis of 9 time-adjusted comparable sales from the 2023–2024 statutory study period, and (2) Most-similar comp analysis anchored to the sale most closely matching the subject's size, age, and quality. Both approaches were reconciled to arrive at the indicated value. All sale prices were adjusted for market appreciation per COMPER's time-adjustment factors.
