First he needs to get his NMLS license. without that, he cannot originate loans. There are educational and other requirements. It takes some time. To start, go to the NMLS website and read through the information. If you have any questions, call them up. I have found them VERY helpful. The phone number is on the website and the website link is below.
Lastly, you will need to link your NMLS license to whatever company you will originate loans with, whether it is your company or one you work for.
