📍 Boulder County, CO — 2026 Appeal Season

Your Property Is Probably Over-Assessed.

Boulder County's mass-appraisal model uses broad area averages that routinely over-value smaller, older, or less-featured homes. We analyze your property using the county's own comparable sales data and provide a step-by-step appeal guide. If we cannot provide you with a justification to decrease your assessed property value by more than 10%, your order cost will be fully refunded.
