People with low incomes may qualify for affordable rent by asking for help from the United States Department of Housing and Urban Development. The HUD can pay private apartment complexes the necessary amount of monthly rent, which would then lower the bills of the low income tenants. Usually, such government subsidized programs in private housing units are available to senior citizens and people with disabilities. To apply for low income housing for seniors and disabled individuals, applicants need to visit the management offices of the apartment complex and apply there. Anyone who earns below the set income limit can qualify for HUD subsidized rental assistance in private apartment properties.
