lets say you were approved for a home loan at a high interest rate due to a bad score and later you found out that the credit score was bad due to bad information on your credit report. you dispute the negative information later on is it possible to call the bank and ask to lower your interest on that loan because they gave you a rate based on wrong info? lets say it all happen within a few months so refi its not an option
i hope this question makes sense for someboy out there.
Is it a new mortgage or a HELOC. if it is a HELOC you can always PIF and then try again to get a better rate. if you closed on the loan you would have to refi later.
You could ask the bank to lower the rates but IMHO there is probably no chance of it.
If the amount of money that you will lose, due to the higher rate, is significant, then I would contact an attorney to file suit against the reporter of the bad information, and collect damages for the difference.
