I know that going out and applying for a new credit card can effect my credit score in a negative way. I have a LOC with a bank. I think I can get a better interest rate from another bank and if so I would transfer the balance to that bank. To do that they will probably need to do a credit check. Does anyone know if this type of credit inquiry would be harmful to my credit score? I would like to check with several banks to make sure I am getting the best possible rate, however I dont want several credit inquiries on my credit score.
