HUD or the department of Housing and Urban Development is a federal agency responsible for ensuring housing opportunities for Americans. Many properties are listed through HUD as being affordable or subsidized in one way or another. Many of those listings are available through PublicHousing.com and are organized by state and city in easy to find search results.
