Didn't see this before - no, I just waited until my account was active on Mr. Cooper's site, and then logged in with my old account - which they had already linked with my new loan.Source of the post Did you physically mail a check for the first MrC payment? Looks like that's what I'll have to do.
Did you receive a letter (on your account on TMS' website, and via snail mail) from TMS about your mortgage transfer? The 'outbound correspondence). That will have your new Mr. Cooper loan number on it, FWIW.
