A commercial lending assistant works with business accounts to assist them with loans they need for business purposes. Your duties as a commercial lending assistant are to suggest loans that fit each client’s needs, review loan applications and other documents, and process loans for business clients. You then prepare closing packages and documents for the responsible person accepting the loan. Your responsibilities may also include processing payments, contacting clients to collect overdue payments, and offering customer service assistance over the phone, through email, or in person. These positions are typically full-time jobs with banks, credit unions, or lending companies.
