Sale history and market context

MakeMe Estimate: $32.7M (estimated market value), with a likely range of $26.1M to $38.8M (half of recent verified sales in this segment landed inside that range). Computed as the county's full cash value of $28,146,000 times a 1.16 market ratio, measured from 3891 verified arm's-length sale prices vs county values (single-tenant industrial sales across the county, through 2026-06-29). Not an appraisal. How this estimate works.

lower confidence: 8 comparable sales within 3 miles; nearest 0.4 mi. This property type carries wider measured error; treat the estimate as a starting point. Comparable-sale caveat: the estimate is 52% above the $129.09/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. Not an appraisal. How this estimate works.
