Many low-income housing units are sitting empty, despite high demand from those in need. A significant portion of these units are classified as affordable, yet remain unoccupied. This issue affects the poorest individuals in the US, who face severe shortages of affordable homes.

Some individuals, like Mathew Davis, struggle to afford even the most basic housing due to limited income. Davis earns a few hundred dollars a month from donating blood plasma, which is not enough to cover rent. Further details on this issue are available, including information on the financing of low-income housing and the resulting vacancies in certain cities.
