This manual outlines what is needed to develop new multi-family housing. Developing affordable multi-family housing on undeveloped vacant land can require a fairly complicated financing scheme, usually relying on equity raised through the Low-Income Housing Tax Credit program. Topics covered in this manual include the development process, the role of the nonprofit, the use of staff and consultants, financing sources, using the Low-Income Housing Tax Credit, development budgets and cash flows, development fees, community involvement and potential risks and their solutions. This manual is one of 36 included in Enterprise's Community Development Library (CD Library).
