Sale history and market context

MakeMe Estimate: $111M (estimated market value), with a likely range of $88.9M to $132M (half of recent verified sales in this segment landed inside that range). Computed as the county's full cash value of $99,493,272 times a 1.12 market ratio, measured from 3891 verified arm's-length sale prices vs county values (office sales in Phoenix, through 2026-06-29). Not an appraisal. How this estimate works.

lower confidence: 4 comparable sales within 3 miles; nearest 1.4 mi. This property type carries wider measured error; treat the estimate as a starting point. Comparable-sale caveat: the estimate is well above (more than 3x apart from) the $44.23/SF median of the shown comparable sales.
