The mortgage industry plays an essential role in helping people acquire a home or other real estate. A loan officer is a typical position in the field, and the one most home buyers are likely to encounter first. Loan officers are responsible for acting as an intermediary between the borrower and the lender, who is usually, if not always, a bank. You could also be a mortgage underwriter, responsible for finalizing the transaction by approving or denying a borrower based on income, credit, and other factors. Or you could be an escrow agent, responsible for transferring the ownership of a property from one party to another.
