[Highland Park] tax appeal

Hi neighbors, We have our tax appeal scheduled for next week and would greatly appreciate hearing from anyone who already had theirs. We are very confused by the wide range of responses posted by neighbors who have already had theirs. Is there specific evidence we should present, does it matter at all, is it dependent on which person hears the appeal, etc? It is so nice living in a neighborhood where people are so willing to help other neighbors. Thanks in advance. Marsha and Jerry
