Your lender should tell you your credit score for free. If you want to see your credit score prior to going to a lender, it’s also possible to buy it from a credit reporting agency, like Equifax, Experian or Transunion.
You can obtain your credit report for free once a year from www.annualcreditreport.com . This will not tell you a score but it will show you what is being reported on your credit. If everything has always been paid on time, your score should be in great shape.
