How do I fight my Marietta property tax assessment?

Fighting a Marietta assessment means filing a formal written appeal with the Cobb County Board of Tax Assessors, supported by recent comparable sales, an independent appraisal or documentation of a condition issue the county missed. The appeal has to go in by the deadline stated on your annual assessment notice, and there is no fee to file it. An unsatisfying result at that stage can move to the county Board of Equalization. Joel can help pull the comparable sales before you submit it.
