Sale history and market context

MakeMe Estimate range: $1.03M to $1.5M (estimated market value range). This building's own 2025 recorded sale at $1.8M sits 45% above this estimate's midpoint, so we lead with the range rather than a single number. 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 1.8 mi. This property type carries wider measured error; treat the estimate as a starting point. Recent sale check: this building sold for $1,800,000 in 2025; the estimate is about 31% apart. Treat the recorded trade as strong evidence alongside the model. Comparable-sale caveat: the estimate is 31% above the $250/SF median of the shown comparable sales.

The shaded range is the model's measured error band; about half of verified sales in the segment land inside it. Diamonds: recorded arm's-length sales. Not an appraisal. How this estimate works.
