MakeMe Estimate: $2.16M (estimated market value), with a likely range of $1.54M to $2.71M (half of recent verified sales in this segment landed inside that range). Based on 7 verified arm's-length comparable sales (through 2026-06-01). Not an appraisal. How this estimate works.
lower confidence: 0 comparable sales within 3 miles; nearest 5.2 mi. This property type carries wider measured error; treat the estimate as a starting point. Comparable-sale caveat: the estimate is 64% above the $525.11/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.
