What this counts
Flipper parcels, in plain words
Single-family homes the county has not re-rated since they were built (1990 or before), with no remodel on its record, held 10 years or more, in neighborhoods where updated homes of a similar size sold for at least 30% more per square foot than this home’s county value, in sales the county qualified as arm’s-length. Widest gap first. Boulder County (its sales of the last two years, and its permits) and Adams County (the qualified sales of July 2022 to June 2024 the county set its values with, at its price for June 30, 2024).
