MakeMe Estimate range: $10.2M to $14.8M (estimated market value range). This building's own 2024 recorded sale at $18.8M sits 53% 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). Not an appraisal. How this estimate works.
lower confidence: 1 comparable sale within 3 miles; nearest 0.1 mi. This property type carries wider measured error; treat the estimate as a starting point. Recent sale check: this building sold for $18,823,106 in 2024; the estimate is about 35% apart. Treat the recorded trade as strong evidence alongside the model. Comparable-sale caveat: the estimate is 35% below the $231.01/SF median of the shown comparable sales.

Value over time
Dark line: county assessed value per King County tax rolls.

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.
