i remember seeing that mark to market had a program where they would add you to their network if got the default school designation. You may want to call them and ask. I also heard at a conference in vegas last year that the school's clients do search its database when searching for agents. Default School asks for a ton of info on the sign up profile, so that makes sense. A client would have all the info necessary to contact you and add you to its agent list and they would see that you invested in specfic reo and valuation training. It works for me anyway.
The other "face to face" training, at least relating to business development, doesn't add up to me. After you are finished, you get a certificate. At least this way you are in a database that is searchable by asset managers.
