The benefit of accurate, optimized credit report information is massive to both consumers and loan officers. Credit reports are filled with inaccurate negative items, any of which may prohibit financing. Fix the problems, and you can close the loan.
Empowering consumers with the knowledge to manage their credit wisely, and seeing this reflected in positive information on credit reports, helps both the consumer (with a better loan) and benefits the loan officer or mortgage broker (more closed loans).
