This article addresses the problem of the gap in affordable housing in
the United States and the efforts being made to address the gap. At i
ssue are the forms of federal financial support for affordable housing
and the relative roles of private, for-profit suppliers; local public
housing agencies; and nonprofit, community-based developers in provid
ing affordable housing. The primary U.S. vehicle for affordable housin
g production is currently the low-income housing tax credit. While thi
s system has produced nearly 350,000 units of low-income housing, it h
as inherent inefficiencies relative to a direct capital grant and curr
ently requires assembling mortgage financing from a number of sources.
Congress and the Clinton administration have been reluctant to encour
age much additional development by public housing agencies, and the ca
pacity of nonprofit, community-based developers is still limited. Expe
riments are under way on a variety of credit enhancement and risk-shar
ing techniques.
