MakeMe Estimate: $1.25M (estimated market value), with a likely range of $1.1M to $1.44M (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: 0 comparable sales within 3 miles; nearest 6.9 mi. This property type carries wider measured error; treat the estimate as a starting point. Recent sale check: this building sold for $780,000 in 2024; the estimate is about 60% apart. Treat the recorded trade as strong evidence alongside the model. Comparable-sale caveat: the estimate is 41% below the $471.64/SF median of the shown comparable sales.
