After starting a new car loan does it matter when you refinance if you desire to do so and could it adversely affect your credit report or score in any way?
If you are asking about refinancing of a home, then it may have an impact on your ability to get the loan. Some lenders will pull an updated credit report before closing papers are sent to the closing agent. But most lenders only pull credit at the time of application or when the file is received in underwriting. So basically it depends on the policies of the bank that you are doing financing with. Also if you shop your rate for the car loan it may look like several inquiries on your credit report and you will have to write a letter of explaination. Typically credit scores are not effected to much my having lenders pull your credit report, maybe 1-5 points each time a report is pulled.
