A credit score measures a consumer’s credit risk relative to the rest of the U.S. population, based on the individual’s credit usage history. The credit score most widely used by lenders is the FICO® score, developed by Fair, Issac and Company. This 3-digit number, ranging from 300 to 850, is calculated by a mathematical equation that evaluates many types of information that are on your credit report. Higher FICO® scores represents lower credit risks, which typically equate to better loan terms. In general, credit scores are critical in the mortgage loan underwriting process.
