Reading owner names on Multnomah County records
Owner fields on county records can be puzzling: 'Estate of', 'et al' and 'c/o' entries near Portland each mean something different. Compare the mailing address with the location: a management company in the field often means rental or investment ground in Multnomah County, worth noting before you write. Owner names on the Multnomah County map lag behind the courthouse, which means a deed filed this season may be missing.
