Sale history and market context
MakeMe Estimate: $2.22M (estimated market value), with a likely range of $1.56M to $2.81M (half of recent verified sales in this segment landed inside that range). Based on 8 verified arm's-length comparable sales (through 2026-06-01). The county roll carries a nominal improvement value for this parcel, so the estimate leans on comparable sales and the county-confirmed building area rather than the county land and improvement split. Not an appraisal. How this estimate works.
lower confidence: 1 comparable sale within 3 miles; nearest 2.3 mi. This property type carries wider measured error; treat the estimate as a starting point. Comparable-sale caveat: the estimate is 62% above the $674.31/SF median of the shown comparable sales.
