I'm 20yrs old and I want to know how to become residential mortgage loan officer? Need mentor.?

you dont need ANYTHING to become a loan officer, I took a cl and paid money to become one, but later found out that you dont even need one! if you can get a loan officer to teach you how to do what they do, then you're set to go, some places hire loan officers with no exp. ness. they train for free :)
