Rent Cred analyzes the ways to build your credit score. They follow the process where a lender will use your credit score to determine if they will lend you money and how much interest they will charge you to borrow it. Your credit score is a number calculated from the information in your credit report. It shows the risk you represent to a lender compared to other consumers. Knowing your credit score before a major purchase, such as a car or a home, may help you to negotiate lower interest rates.
