I had an adventure refinancing with Chase and I don't think I'd do it again. They sent me an offer to refi so I started the process. Then they told me that I didn't qualify, then told me I did qualify, and also were going to charge me a significant fee. I couldn't get straight answers from them at all.
In the meantime, I got yet ANOTHER offer from Chase to refi, with zero closing costs, no fees, etc. The Chase people from the first offer found out that I got the second offer, tried to invalidate it, and told me I had to go through them. I told them to get screwed and fortunately, I had filed all the paperwork with the second group and they had submitted everything before the first group found out. So I dropped from 6.125 to 5.125, no fees, and the lady came to my house one night and my wife and I signed everything.
