lower confidence: 1 comparable sale within 3 miles; nearest 2.7 mi. This property type carries wider measured error; treat the estimate as a starting point. Comparable-sale caveat: the estimate is 94% above the $193.89/SF median of the shown comparable sales.

Value over time
Dark line: county assessed value per King County tax rolls. Blue line: our estimate; dashed years are a modeled backcast built from recorded arm's-length sales in the building's segment, not estimates published at the time, and years without enough sales stay unmodeled. 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.
