I rate locked yesterday. Rates are so historically low and treasuries can't really go that much lower.
I felt like there is a chance for treasury rates to go up post election.
I got an amazing rate on a 30 year fixed refi that I cant imagine it getting much lower, and I would feel like I missed an opportunity to lock in a great rate for 30 years if I didn't lock it.
If rates go down 1/4% or more, I can renegotiate my rate, but I really see that as extremely unlikely.
My 2 cents
