Fannie Mae Enhances Monthly Loan Level Delinquency Data Report for Single-Family Pools

Beginning with the August 2018 publication of the Monthly Loan Level Delinquency Data report, Fannie Mae will be updating the Mortgage-Backed Securities (MBS) Pass-Through Rate range to "less than 2.5%" through "6.0% and greater" with 50 bps increments in between. This is an extension from the current range of "less than 4.5%" through "7.0% and greater."

Additionally, we have removed the following products from the "Conventional Fixed Rate" Category and included them in the "Other" Category:

  • 40 Year (CZ prefix)
  • Interest Only (all "N" prefixes)
  • Prepayment Premiums (all "K" prefixes)

The report will continue to be available in .pdf and .xlsx formats.
