So so. The big money, as in most industries, comes from being in sales. If you like the world of transacting in mortgages, sell them. Being a mortgage broker, owning the client, directing their dollars, and so on.
The average annual salary for this career is in the neighborhood of $65k, but if you're in the majority of loan officers who are paid a commission, you're more concerned with how many loans you bring in and, accordingly, how many bonus dollars you’re able to score.
As long as you aren't irresponsible with your money, you should be able to make a comfortable living on a loan officer's salary, which is good, because you don't want to be the loan officer who has to ask for a loan. Talk about embarrassing.
