This report explores strategies used by nonprofit organizations, for-profit developers, and city agencies to ensure low- to-moderate-income residents can live in revitalizing neighborhoods. Strategies used to prevent displacement are influenced by a number of factors, including housing market strength, political climate and organizational capacity. Through six case studies, researchers consider the impact of timing on strategy selection and implementation to untangle whether certain approaches work better in different housing-market contexts. See the companion document, Keeping the Neighborhood Affordable: A Handbook of Housing Strategies for Gentrifying Areas, for a discussion of additional affordable housing strategies.
