Sale history and market context

MakeMe Estimate: $14.7M (estimated market value), with a likely range of $11.8M to $17.5M (half of recent verified sales in this segment landed inside that range). Computed as the county's full cash value of $13,220,628 times a 1.11 market ratio, measured from 3891 verified arm's-length sale prices vs county values (office sales in Scottsdale, 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 well above (more than 3x apart from) the $14.35/SF median of the shown comparable sales.

Dark line: county assessed value per Maricopa County tax rolls. Blue line: our estimate; dashed years are a modeled backcast built from recorded arm's-length sales in the building's segment, not estimates published at the time, and years without enough sales stay unmodeled. 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.
