No, use the GMI codes that were provided by the borrower at the time of application. Depending on how the app was taken , if there were no GMI codes used then the correct codes would be "Not Provided".
However, if the borrower on the loan is a non-entity, i.e. a corporation, then the GMI codes would be "Not Applicable".
