The bulk of the funds Mr. Hogan's administration has identified come in the form of revenue bonds to be issued by the Department of Housing and Community Development through two programs. One is the Rental Assistance Demonstration Project, an Obama administration initiative to privatize public housing in an effort to tap private sector resources for repairs and renovations. Baltimore is already deeply engaged in that effort. The other is multifamily revenue bonds, which can be used to support acquisition, renovation or construction of low-income housing. Together, they account for about $432 million, or more than half of the promised total. Another $45 million would come from revenue bonds issued through an existing program at the Department of Commerce that provides a similar financing mechanism for small businesses in priority funding areas to acquire land, build facilities, buy equipment, etc.
