Early directions for financing of housing and support services in the community included financing sources, such as housing cooperative programs, mixed income housing associations, community development block grants, loans for accessibility programs, tax exempt bonds, trust funds, housing subsidies, and low interest loans [REF].
The US Department of Housing and Urban Development regularly makes available free information on housing financing and developments in the US through their website, including "Research Works" (in 2011, also on sustainability and green initiatives) and "US Housing Market Conditions".
