Do mortgage lenders use FICO 8? (EFX, TRU)

FICO 8 is a credit-scoring system released in 2009. Since then, only a few lenders have adopted it. The vast majority of lenders still rely on FICO 2, 4 and 5 scores, which are all part of a larger report mortgage lenders can obtain called the residential mortgage credit report (RMCR). This report contains credit reporting on an individual from all three major credit reporting agencies: Equifax Inc. (EFX), Experian PLC (EXPN) and TransUnion (TRU). Mortgage lenders usually take the middle score from this report. For example, if your credit scores from the above agencies are 710, 690 and 610, the lender typically makes its decision based on the 690 score. 

It is assumed that the majority of mortgage lenders have not adopted the new FICO 8 score because they are generally slow-moving entities, even in prosperous times. Also, due to the recent market crises, mortgage lenders have more urgent issues to consider. Note further that the lenders' FICO 2, 4, and 5 scoring systems have served the purpose. 

The Major Changes to FICO 8

However, more lenders are likely to migrate to FICO 8, so it is important to understand the five reasons why it makes the score different. First, FICO 8 is more sensitive to highly-used credit cards. Higher balances, even on frequently used and paid cards, may have more of a negative impact. Second, FICO 8 is more lenient to isolated late payments, but frequent late payments are penalized more. Third, FICO 8 is more careful with, and more sensitive to, authorized users on credit cards. Fourth, small-balance delinquencies of under $100 are ignored. Finally, consumers are divided into many more categorical profiles under FICO 8.
