Sale history and market context

MakeMe Estimate: $1.93M (estimated market value), with a likely range of $1.55M to $2.29M (half of recent verified sales in this segment landed inside that range). Computed as the county's full cash value of $1,687,360 times a 1.15 market ratio, measured from 3891 verified arm's-length sale prices vs county values (office sales across the county, through 2026-06-29). Not an appraisal. How this estimate works.

lower confidence: 4 comparable sales within 3 miles; nearest 0.7 mi. This property type carries wider measured error; treat the estimate as a starting point. Comparable-sale caveat: the estimate is 93% above the $177.01/SF median of the shown comparable sales.
