We have seen several instances where an individual has applied for a loan and either another individual (spouse) has joined with the 1st to apply for the credit at a later time or underwriters requested another co-applicant. No counteroffer was made to 1st applicant, no new application was made for both. Both were denied. My question is: In these cases, do we report GMI for the original applicant, both applicants, or report GMI based on whose income was used to make the credit decision?

IMO report what was used to make the credit decision.
