Mutual Federal Bank is a community savings bank based in Chicago that operates through a single branch location. The bank's core business consists of gathering deposits from local retail customers and small businesses and deploying that capital into real estate lending across the Chicago metropolitan area. Its loan portfolio primarily comprises one-to-four-family residential mortgages, alongside multifamily and commercial real estate loans. The bank does not offer consumer, auto, or commercial and industrial loans. In addition to originating loans directly, the bank expands its residential lending book by purchasing mortgage loans from local community banks and mortgage originators under its own underwriting standards. Mutual Federal Bank operates on a traditional thrift business model, generating nearly all of its revenue from net interest income earned on the spread between loan yields and funding costs from customer deposits and Federal Home Loan Bank borrowings. The bank maintains a simplified balance sheet centered on loans and cash rather than an investment securities portfolio, and it earns minimal non-interest income. Strategically, the bank is shifting its lending mix toward multifamily and commercial real estate while pursuing a mutual-to-stock conversion to expand its lending capacity and support future growth.
