Investing in a Community Development Financial Institution (CDFI) is a powerful way to directly engage in the local economy and increase access to capital in minority, underserved communities. With the generous support of the Satterberg Foundation, this guide was developed to help board and staff members in the philanthropic sector examine the basic processes of building a relationship with a CDFI and structuring investments in it. Insights from Northwest Area Foundation and Meyer Memorial Trust, two Philanthropy Northwest members with deep experience supporting CDFIs, are also included.
