RHS administers direct loans, loan guarantees and grants. Direct loans are made and serviced by USDA staff; loan guarantees are made to banks or other private lenders, and grants are made directly to a person or organization. RHS works with other federal agencies, and a number of both nonprofit and private organizations nationally, in order to pool resources to help America's rural residents most effectively. The RHS National Office is located in Washington, D.C., and is responsible for setting policy, developing regulations, and performing oversight. In the field, RHS operations are carried out through the USDA's state and local Rural Development offices and service centers, several of which are located in each state and Puerto Rico. The Customer Service Center, located in St. Louis, Missouri, provides loan origination and servicing directly to RHS Single-Family Housing borrowers. For all Rural Development programs, the rural area definition was revised by the 2014 Farm Bill. Specifically, the Farm Bill allows some areas with populations up to 35,000 to remain eligible until receipt of the 2020 decennial census. Effective February 2, 2015, areas with populations greater than 35,000 no longer qualify for Rural Housing Program assistance. Please see below for detailed definition: To RHS, a rural area is either an open country or any town, village, city, or place, including the immediate adjacent densely settled area, which is not part of or associated with an urban area and which: Has a population not in excess of 2,500 inhabitants; or Has a population in excess of 2,500 but not in excess of 10,000 if it is rural in character; or Has a population in excess of 10,000 but not in excess of 20,000, and- Is not contained within a Metropolitan Statistical Area; and Has a serious lack of mortgage credit for lower and moderate-income families as determined by the Secretary of Agriculture and the Secretary of Housing and Urban Development. Any area classified as ‘‘rural’’ or a ‘‘rural area’’ prior to October 1, 1990, and determined not to be ‘‘rural’’ or a ‘‘rural area’’ as a result of data received from or after the 1990, 2000, or 2010 decennial census, and any area deemed to be a ‘‘rural area’’ at any time during the period beginning January 1, 2000, and ending December 31, 2010, shall continue to be so classified until the receipt of data from the decennial census in the year 2020, if such area has a population in excess of 10,000 but not in excess of 35,000, is rural in character, and has a serious lack of mortgage credit for lower and moderate-income families. An exception to the rural eligibility requirements is the Farm Labor Housing Program, which is the only federal program available for development of housing for farm workers. This program is available in both rural and urban areas.
