A solid credit history can be one of your most useful and powerful financial assets. A record of prudent credit use and prompt payments can enable you to not only qualify for credit when you need it, but it may also enable you to get a lower interest rate on your borrowing.
The three main credit agencies that gather financial information on individuals and then make that information available to lenders to help them determine whether to make a loan to someone are TransUnion, Experian, and Equifax. The information they compile includes a great deal of basic data such as age, Social Security number, current and previous addresses, employers and marital status. They also get information on your borrowing history from places you have borrowed such as credit cards issuers, mortgage lenders and others. Your credit report probably includes all the credit relationships you have, date established, maximum allowed credit, current balances and payment history.
Lenders will use a credit report, along with evaluating your capacity to repay, your character and any collateral in making decisions to lend you money. Many lenders also take these same issues into account in deciding what interest rate to charge or type of loan to offer.
