Sale history and market context

MakeMe Estimate: $1.06M (estimated market value), with a likely range of $769K to $1.32M (half of recent verified sales in this segment landed inside that range). Based on 8 verified arm's-length comparable sales (through 2026-06-01). Not an appraisal. How this estimate works.

lower confidence: 2 comparable sales within 3 miles; nearest 1.4 mi. This property type carries wider measured error; treat the estimate as a starting point. Recent sale check: this building sold for $456,000 in 2023; the estimate is about 133% apart. Treat the recorded trade as strong evidence alongside the model. Comparable-sale caveat: the estimate is 37% below the $366.49/SF median of the shown comparable sales.
