Which of the following is not considered a funding source for mortgages?

Investment firms are not typically considered direct funding sources for mortgages in the same way that banks, credit unions, and trust companies are.

Banks are traditional and well-known lenders that provide mortgages directly to borrowers by using their own capital. Credit unions, as member-owned financial cooperatives, also provide mortgage loans, often focusing on serving their local communities and members. Trust companies, which manage assets on behalf of clients, can offer mortgage products, although they may operate slightly differently from banks.

Investment firms, on the other hand, primarily focus on investing in various financial assets and may not directly provide mortgage funding to consumers. Instead, they might invest in mortgage-backed securities or other investment products related to the mortgage market, but they do not originate mortgages in the same manner as the other entities.
