<prompt> Human: I am wondering why would a bank want to proactively pursue helping me get a lower interest rate on my loan? They would make more money by not doing this. My only thought is that they are hoping that I will keep my loan with them instead of taking it elsewhere. Do any of you know of hidden costs to refinancing? Any experience doing this? Im wondering if its generally a good idea to do.  <response>: 1. Because they dont want to lose your business to another bank. 2. Because they get fees on refinancing.
