As a mortgage loan assistant, your responsibilities involve providing support to a loan officer, mortgage specialist, or another mortgage professional in a bank or similar lending institution. You may specialize in commercial or residential mortgages, or handle both. Your duties may include assessing applications for accuracy and financial information, communicating with the potential borrower to gain the necessary documentation for the lending process, and entering the data required in a mortgage application or other paperwork. You also act as the first point of contact for applicants and borrowers who have questions during or after the approval process.
