Fannie Mae has updated the credit score used by DU

Fannie Mae has updated the credit score used by DU in its eligibility assessment to support 

homeownership opportunities for more underserved borrowers.  DU will no longer use the lowest of 

the middle credit score to confirm mortgage loans comply with Fannie Mae’s minimum credit score

 requirement of 620. DU may offer eligibility of these loan casefiles with the use of an average 

median credit score.                                                   

How does this update in DU benefit my borrowers? Do they have to meet a 620 credit score?


Pickup: An increase may be seen in DU with “Approve/Eligible” recommendations based on average 

calculation of all borrower’s middle scores. This scoring method will be used behind the scenes in 

DU for credit eligibility purposes only. Please refer to Fannie Mae guidelines in the following KO 

topics: Credit Scores and AUS Risk Analysis.

Examples:

DU Casefiles:

Number of Borrowers on the Loan Application

Step 1: Determine each borrower's median score

Step 2: Average the median scores to determine casefile score


Scores: 590, 605, 648 / Median: 605

Scores: 590, 605, 648 / Median: 605

Scores: 661, 693, 693 / Median: 693

Fannie Mae has updated the credit score used by DU


Average: Not applicable

DU Representative Credit Score: 605 Average: (605 + 693) / 2 = 649

DU Representative Credit Score = 605

Pricing: The average median score will not be used for pricing. Pricing will continue to be based 

on the Representative Credit Score. When the Representative Credit Score falls below 620 due to DU 

using the average median score for qualifying, pricing will be dropped a tier to price below

 620. OB has been updated with the changes required to allow for a less than 620 Representative 

Credit Score; manual locking process is not required.
