With the appearance of automated underwriting in 1996, the GSEs revolutionized the mortgage lending course of.

Not having adequate credit score efficiency information for loans with credit score scores under 620 subjected the fashions to errors in estimating credit score danger for these debtors and consequently posed greater losses for each GSEs.
