Is having a copy of the original application important?

[Sandy Uhlmann]

I am in the process of purchasing a note.  Seller tells me that they don't have a copy of the original application.  Is this important?  Am I able to pull credit through a third party vendor without it?

I know that FCI tells me that they need it for them to pull credit.  Is there other reasons that having a copy of the original application is necessary?
