MakeMe Estimate: $93.8M (estimated market value), with a likely range of $89.6M to $102M (half of recent verified sales in this segment landed inside that range). Based on 6 verified arm's-length comparable sales (through 2026-06-01). Not an appraisal. How this estimate works. About $353K per unit at the midpoint (266 units).

lower confidence: 1 comparable sale within 3 miles; nearest 2.9 mi. Last arm's-length sale: $113,934,000 in 2022.

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.
