Mercantile Bank Corporation is the holding company for Mercantile Bank of Michigan (formerly Mercantile Bank of West Michigan), which operates more than five branches in and around Grand Rapids, Holland, and Lansing. (The latter was the community bank's first foray outside the western part of Michigan, prompting the name change in 2005.) The bank targets local consumers and businesses, offering standard deposit services such as checking and savings accounts, CDs, IRAs, and health savings accounts. Loans for real estate secured by nonresidential properties make up more than half of the company's loan portfolio; business loans are about a quarter.
