Which act aims to expand affordable housing availability through government support?

The National Housing Act is aimed at expanding the availability of affordable housing through various forms of government support. This act was originally established to create a framework for improving housing standards and expanding access to housing for lower-income individuals and families. It includes provisions for mortgage insurance, which makes it easier for people to attain loans for purchasing homes. By reducing financial barriers for both lenders and borrowers, the National Housing Act facilitates the process of securing affordable housing, thereby directly addressing housing shortages and enhancing affordability.

The other acts listed, while important for different aspects of housing policy, serve other specific purposes that do not primarily focus on expanding affordable housing through government support. For example, the Fair Housing Act focuses on preventing discrimination in housing, the Homeless Assistance Act provides aid and services to homeless individuals, and the Housing Opportunities Through Modernization Act aims to streamline housing assistance programs, but doesn't primarily emphasize government-backed affordability initiatives.
