It is reported as missing rather than estimated, and an absent line never means zero. ## Source and method Every fact above is a fact about this parcel, taken from county assessor and recorder records and restated unchanged. Nothing is modelled, averaged, inferred from a neighboring parcel, or filled in from a comparable one. Where the record holds no value, the line is absent rather than estimated, and an absent line never means zero. Counties record on their own schedules, so a fact can be accurate as recorded and still lag a change on the ground. ## How to cite this - Canonical: https://cobroker.ai/property/wa/king/mercer-island/5315101105 - Source: Cobroker - Methodology: https://cobroker.ai/methodology ## Owner contacts and site analysis Most commercial parcels are held under an LLC, and the county record names the entity, not the people.
