Seniors, people with disabilities, and other families who meet the requirements set by the local housing authority may also qualify. In most cases, applications are submitted online when the local housing authority opens the process, although some agencies also offer in-person or phone options. Experts recommend checking the official website of the housing authority for the city or county where you want to live to find out when waiting lists will reopen. In general terms, the family typically pays about 30% of its adjusted income, while the program covers the rest—up to the limit set by the local housing authority. If the approved rent were $2,300, the program could cover about $1,100, as long as the home meets the rules and limits set by the local authority.
