Sale history and market context

MakeMe Estimate: $10.6M (estimated market value), with a likely range of $8.69M to $12M (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). Not an appraisal. How this estimate works.

lower confidence: 0 comparable sales within 3 miles; nearest 4.6 mi. This property type carries wider measured error; treat the estimate as a starting point. Comparable-sale caveat: the estimate is 35% above the $208.92/SF median of the shown comparable sales.

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. Not an appraisal. How this estimate works.
