Sale history and market context

MakeMe Estimate: $6.3M (estimated market value), with a likely range of $5.03M to $7.47M (half of recent verified sales in this segment landed inside that range). Computed as the county's full cash value of $5,403,582 times a 1.17 market ratio, measured from 3891 verified arm's-length sale prices vs county values (office sales in Mesa, through 2026-06-29). Not an appraisal. How this estimate works.

lower confidence: 6 comparable sales within 3 miles; nearest 1.2 mi. This property type carries wider measured error; treat the estimate as a starting point. Recent sale check: this building sold for $12,709,526 in 2025; the estimate is about 50% apart. Treat the recorded trade as strong evidence alongside the model. Comparable-sale caveat: the estimate is well above (more than double apart from) the $103.62/SF median of the shown comparable sales.
