2&U was a downtown Seattle "alley project" and the SAM (Seattle Art Museum) as included/abutting for former WAMU Center (owned by Second and Union, LLC, a subsidiary of Washington Mutual BANK), along with all of the other business and real estate owners, did minor property adjustments to accomplish the project objects "for the minimum transaction fee."
The value that you put on the "alley transfer" is actually the total assessed value of the Seattle Art Museum that is the TAX EXEMPT portion for the; the small difference is for the floors that are "rented" and are NOT TAX EXEMPT.
