We start with a free property assessment review to determine if an appeal makes financial sense. If we identify potential savings, we'll conduct a detailed property analysis including market research and comparable sales studies. Our team then prepares and files all necessary paperwork with the appropriate tax authorities. Throughout the appeals process, we handle all communications with assessors and represent you at hearings. We keep you informed of progress and explain each step in plain language. Most residential cases resolve within 3-6 months, while commercial appeals may take 6-12 months depending on complexity.
