      (07/25/2017) Introduction This topic contains information on the following:
      Accuracy of Credit Information in a Credit Report Disputed Tradelines Accuracy
      of Credit Information in a Credit Report For all mortgage loans (including DU
      loan caseﬁles and manually underwritten loans), the lender is responsible for
      reviewing the credit report, as well as all credit information, to determine
      that the credit report meets Fannie Mae''s requirements and that the data evaluated
      by DU was accurate. If a borrower indicates that any signiﬁcant information
      in the credit ﬁle is inaccurate—such as reported accounts that do not belong
      to the borrower or derogatory information that is reported in error—the lender
      should carefully review the credit information with the borrower, then request
      the credit reporting company that provided the information to conﬁrm its accuracy.
      Disputed Tradelines Manually Underwritten Loans If the borrower has disputed
      information in their credit ﬁle, and the credit reporting company conﬁrms that
      the disputed information is incorrect or incomplete and underwriting the loan
      needs to be completed before the credit ﬁles can be corrected, the lender cannot
      use the credit score(s) when manually underwriting the loan. Instead, the credit
      risk assessment must be based on a review of the borrower’s traditional credit
      history. If there are multiple disputed tradelines or a dispute on a mortgage
      tradeline, the lender should obtain Published May 6, 2026 465 correspondence
      directly from the borrower indicating the reason for the dispute. The aspect
      of the tradeline–such as balance and payment history–that is being disputed
      is of particular interest when considering the impact to the borrower’s overall
      credit proﬁle. The lender is responsible for determining whether the borrower’s
      explanation is reasonable and/or whether additional documentation (such as canceled
      checks) is necessary to disprove the adverse information. Lenders are not required
      to investigate disputed medical tradelines. DU Loans For loan caseﬁles underwritten
      through DU, DU will indicate if the lender is required to investigate the disputed
      account to determine if the account belongs to the borrower and conﬁrm the accuracy
      and completeness of the information reported on the account. See B3-2-09, Erroneous
      Credit Report Data; B3-2-10, Accuracy of DU Data, DU Tolerances, and Errors
      in the Credit Report; and B3-5.3-09, DU Credit Report Analysis for additional
      information. Recent Related Announcements There are no recently issued Announcements
