  Why your credit file can cost you more in rates a fees  
  Lenders use your credit report and credit score to determine the overall risk they will assume if they lend you money. The lower your credit score, the more risk you entail. In order to cover themselves against this risk, lenders will charge a higher interest rate on loans to those with bad credit. They will also require additional fees upfront in order to cover costs that can usually be rolled into a loan. As shown in the “Cost of bad credit” section, higher interest rates result in substantially higher costs over the life of a mortgage.
