Here are the instructions but I don’t believe you’ll find any specific information on this section. I recommend you complete it to the best of your ability based on how you receive the information. For the scenarios you mentioned:
1)Officer e-mails a loan application to the client and the client e-mails the application back, would the loan officer complete this section as “mail?” I would mark “email or internet”
2)Same goes, if a client is e-mailed the application and then the client drops off the application to loan officer (without speaking any further details of the transaction),
I would mark “face to face”.
