MakeMe Estimate: $1.26M (estimated market value), with a likely range of $1.11M to $1.46M (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). Not an appraisal. How this estimate works.
lower confidence: 1 comparable sale within 3 miles; nearest 0.2 mi. This property type carries wider measured error; treat the estimate as a starting point. Comparable-sale caveat: the estimate is 28% below the $471.64/SF median of the shown comparable sales.

The shaded range is the model's measured error band; about half of verified sales in the segment land inside it. Diamonds: recorded arm's-length sales. Not an appraisal. How this estimate works.
