This session will present a case study on the 2024 revaluation of Central Falls, a small city with 3,000 parcels, comparing modern revaluation tools like regression and AVM against traditional market-adjusted cost methods. Additionally, we will explore a real estate data visualization tool created for Philadelphia (~ 600,000 parcels) which integrates city and external data sources to support decision-making for various users like homeowners, developers, and city planners.
