MakeMe Estimate: $6.83M (estimated market value), with a likely range of $6.03M to $7.89M (half of recent verified sales in this segment landed inside that range). Based on 7 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 0.5 mi. This property type carries wider measured error; treat the estimate as a starting point. Recent sale check: this building sold for $6,950,000 in 2024; the estimate is about 2% apart. Treat the recorded trade as strong evidence alongside the model. Comparable-sale caveat: the estimate is 63% above the $238.93/SF median of the shown comparable sales.
