In many regions around the country, the demand for affordable housing is greater than the supply. Wait lists have traditionally been the method of choice for determining who is “up next” to get housing. In order to improve their chances, people in need of housing are often encouraged by staff at multi-service agencies to get their names on as many lists as they can.
