How do lenders determine who is approved for a credit card, mortgage, or car loan? Why are some individuals flooded with credit card offers while others get turned down routinely? Because creditors keep their evaluation standards secret, it is difficult to know just how to improve your credit rating. It is important, however, to understand the factors and to review your credit report periodically for any irregularities, omissions, or errors. Reviewing your credit report annually can help you protect your credit rating from fraud and ensure its accuracy.
