Sale history and market context

MakeMe Estimate: $22.4M (estimated market value), with a likely range of $16.8M to $26.5M (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). 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: 6 comparable sales within 3 miles; nearest 1.6 mi. This property type carries wider measured error; treat the estimate as a starting point. Comparable-sale caveat: the estimate is well above (more than 3x apart from) the $121.58/SF median of the shown comparable sales.

Comparable sales used as evidence

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.
