The third quarter produced the office market's first negativenet absorption in three quarters, with negative 79,284 square feet.This reduces the year-to-date total positive absorption to 20,944square feet. The Q3 2014 average asking rate on a full servicebasis for tracked office product in the Tucson market was recordedat $19.47 per square foot per year, up $0.19 from Q2 2014, whichwas $19.28. As a comparison, the Q3 2013 rate was recorded at$19.35, which is in between the Q2 2014 and Q3 2014rates. With limited new tenants in the market and ampleavailable space, the Tucson office market has seen many existingtenants take the opportunity to upgrade their offices. Conversely,with insufficient new tenant activities, landlords have beenmotivated to move space, and have offered lower rates and/orconcessions in high quality vacant space.
