The Strong Families Fund is the largest pilot pay-for-performance project to finance Resident Service Coordination (RSC) in affordable housing for lower-income families. The initiative was created to measure the impact of resident service coordination on tenant and building performance within affordable housing. The performance-based contract approach helps to align all collaborating partners with a shared vision of success. This report reviews the results of the data collected through the first phase of the initiative. It demonstrates that using this performance-based approach to resident service coordination in affordable housing is a powerful way to increase economic mobility, health & well-being, housing stability, and community engagement and safety.
