New York City Early Warning System for Housing Abandonment

A collaborative project with the NYU Center for Urban Real Estate and Law (M. Schill) and the Wharton Real Estate Center (S. Wachter) to develop a forecasting model and decision support Geographic Information System (GIS) for anti-abandonment efforts in New York City. This project involved the integration of over a dozen municipal databases on housing and real estate in NYC at the parcel level, and covering ten years, yielding a longitudinal, property-specific database for conducting research on housing and neighborhood trends. The data and various analysis tools were incorporated into a web-enabled GIS so that city agencies and community organizations could potentially view and manipulate the underlying data in the model, as well as view customized reports by property, regarding ownership, building characteristics, tax arrearages, code violation history and city actions.
