Appraisal Methodology
Our Diminished Value Appraisal is based on a data driven valuation framework that reflects real-world market behavior, established appraisal principles, and recognized industry data sources. The methodology determines the loss in fair market value resulting from an accident, even after the vehicle has been fully repaired to operational condition.
Valuation conclusions are based on comparative market analysis, adjusted indicators, and loss severity, in accordance with the Uniform Standards of Professional Appraisal Practice (USPAP). The process begins by establishing the pre-loss fair market value through verified listings of comparable vehicles with no accident history, matched by year, make, model, trim, mileage, and condition, using data from Kelley Blue Book, J.D. Power/NADA, Black Book, and dealer inventories.
The post-loss fair market value is then determined using comparable listings of vehicles with verified accident histories from Carfax and AutoCheck, with adjustments for feature differences, mileage, and regional pricing. The difference between pre-loss and post-loss values defines the baseline diminished value, refined to account for buyer perception and market stigma—particularly when structural or safety-related repairs are involved.
Expert Witness
Our network of appraisers have experience providing expert witness support in disputes involving motor vehicle accident (MVA) property damage—including diminished value and total loss valuation cases. When needed, they can help defend the methodology, explain comps and adjustments, and support SnapClaim appraisal reports through litigation, arbitration, or appraisal clause processes.
