MakeMe Estimate: $545K (estimated market value), with a likely range of $481K to $629K (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: 3 comparable sales within 3 miles; nearest 0.2 mi. This property type carries wider measured error; treat the estimate as a starting point. Last arm's-length sale: $525,000 in 2022. The market has moved since; the estimate reflects current county values and ratios, not that price. Comparable-sale caveat: the estimate is 56% above the $285.58/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.
