This could be the saga of How the MidWest Was One. MidWestOne Financial Group is the holding company for MidwestOne Bank, which operates around 20 branches in south-central and eastern Iowa. The banks offer standard deposit products such as checking and savings accounts, CDs, and IRAs, in addition to trust services, credit cards, insurance, and brokerage and investment services. More than 60% of MidWestOne Financial's loan portfolio consists of real estate loans, including residential and commercial mortgages and agricultural and construction loans.
