Real Estate tax is based on fair market value, which is ultimately determined by the tax assessor at the county. Reviewing the assessments (a.k.a. Valuations or appraisals) and appealing them follows very specific guidelines and timeframes. Sometimes this process can lead to presenting your case before a board of equalization. We have presented to boards of equalization across the state of NC and the southeast. These assessments determine the taxes paid by clients for up to 8 years, so if the opportunity to appeal is not recognized this can cost a client greatly.
