Countrywide Loan Underwriting Expert System

Countrywide Loan Underwriting Expert System (CLUES (TM)) is an advanced, automated mortgage underwriting rule-based expert system. The system was developed to increase the production capacity and productivity of Countrywide branches, improve the consistency of underwriting, and reduce the cost of originating a loan. The system receives selected information from the loan application, credit report, and appraisal. It then decides whether the loan should be approved or whether it requires further review by a human underwriter. If the system approves the loan, no further review is required and the application is funded. CLUES has been in production since February 1993 and is currently processing more than 8500 loans per month in over 300 decentralized branches around the country.
