Sale history and market context

MakeMe Estimate range: $14.1M to $25.3M (estimated market value range). This building's own 2022 recorded sale at $37.6M sits 87% above this estimate's midpoint, so we lead with the range rather than a single number. Based on 4 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: 1 comparable sale within 3 miles; nearest 2.4 mi. This property type carries wider measured error; treat the estimate as a starting point. Last arm's-length sale: $37,615,000 in 2022. The market has moved since; the estimate reflects current county values and ratios, not that price. Comparable-sale caveat: the estimate is 76% above the $324.68/SF median of the shown comparable sales.

Market context: Industrial in Redmond

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.
