Same building type, by distance. Assessor facts only; not an opinion of value.
MakeMe Estimate: $506K (estimated market value), with a likely range of $423K to $616K (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: 1 comparable sale within 3 miles; nearest 2.2 mi. This property type carries wider measured error; treat the estimate as a starting point. Comparable-sale caveat: the estimate is 28% above the $350.08/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.
