How It Works
Form Submission
We recommend that you submit our Inquiry Form as soon as you receive your new property valuation notice, which will initiate a request for a complimentary analysis of the assessed value. Note that it may take 2-3 weeks to complete the analysis, and you are under no obligation to use our services based on our findings.
Complimentary Analysis
During our analysis, we review comparable sales in the area and consider any unique factors—such as deferred maintenance, wetlands, or recent appraisals. For commercial properties, we also conduct a confidential income and expense analysis to ensure the most accurate results.
Appeal Process
If your property is overvalued and you hire us to represent you, we’ll handle the appeal—filing the petition and presenting your case at the Board of Equalization. You pay a filing fee and only a percentage of the tax savings if we win—nothing more if we don’t.
