Sale history and market context

MakeMe Estimate: $31.6M (estimated market value), with a likely range of $29.7M to $35.6M (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). The county roll carries a nominal improvement value for this parcel, so the estimate leans on comparable sales and the county-confirmed building area rather than the county land and improvement split. Not an appraisal. How this estimate works.

lower confidence: 8 comparable sales within 3 miles; nearest 0.9 mi. This property type carries wider measured error; treat the estimate as a starting point. Comparable-sale caveat: the estimate is 82% below the $524.32/SF median of the shown comparable sales.
