Yea I noticed that clause in the note, it wasn't in the old one. I could not get them to either change the clause or define a material adverse change in the note. I did get the loan officer to define in an email that a material adverse change would be a change that would not allow me to make payments when due. Not as good as in the document but it is in writing from the loan officer at the bank. I am keeping a copy of it with my loan docs. I figured since the definition wasn't defined in the document and I asked the loan officer for the definition, which they provided, that this would help me a lot if they ever decide to mess with the rate.
I had a 5.75% rate from 4 years ago and got a 3.99% rate through the refinance.
