Credit report costs
By law, each year you can request a free credit report from AnnualCreditReport.com
They will provide you with a report from each of the 3 largest credit agencies in America.
For an additional fee, usually about $15, you can get your "credit score" used by most lenders to determine your ability to repay on a loan.
Best to get your report in advance of applying for a loan, in order to correct any mistakes before the potential lender sees this document.
