A government authority in Wilmington, DE is seeking an experienced vendor to provide independent property assessment services. The selected provider will conduct a comprehensive validation of the most recent countywide property reassessment through professional appraisal and assessment consulting.

Key responsibilities include developing and submitting a detailed project plan, reviewing assessment records, Computer Assisted Mass Appraisal (CAMA) data, GIS layers, sales validation reports, and prior ratio studies. The engagement will require residential field inspections and the development of methodologies for commercial property valuations, which may offer alternatives to the agency's current assessment approaches.

The vendor will also be responsible for public outreach, preparing presentation materials suitable for elected officials, public meetings, and publication on the agency's website. Additionally, the scope involves statistical analysis and reporting, including conducting ratio studies for residential and commercial samples, measuring key metrics such as the Coefficient of Dispersion (COD), Price–Related Bias (PRB), and other IAAO-recommended measures.
