Sale history and market context

MakeMe Estimate: $848K (estimated market value), with a likely range of $678K to $1.01M (half of recent verified sales in this segment landed inside that range). Computed as the county's full cash value of $673,000 times a 1.26 market ratio, measured from 3891 verified arm's-length sale prices vs county values (multifamily sales in Phoenix, through 2026-06-29). Not an appraisal. How this estimate works.

lower confidence: 62 comparable sales within 3 miles; nearest 0 mi. This property type carries wider measured error; treat the estimate as a starting point. Recent sale check: this building sold for $475,000 in 2023; the estimate is about 79% apart. Treat the recorded trade as strong evidence alongside the model. Comparable-sale caveat: the estimate is 52% above the $261.78/SF median of the shown comparable sales.
