Sale history and market context

MakeMe Estimate: $1.19M (estimated market value), with a likely range of $966K to $1.38M (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 3.1 mi. This property type carries wider measured error; treat the estimate as a starting point. Last arm's-length sale: $1,000,050 in 2021. The market has moved since; the estimate reflects current county values and ratios, not that price. Comparable-sale caveat: the estimate is well above (more than double apart from) the $168.39/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. Diamonds: recorded arm's-length sales. Not an appraisal. How this estimate works.
