Simple answer = 60 days worse. 15 days = better.
Is your LO talking to you about these issues? Maybe you SHOULD switch lenders....I don't normally recommend that, but sheesh.... Go to the Directory, upperright hand side of this page, find a premium member in your state and give them a call. We're all professionals, if you're getting an "amazing" deal from someone that doesn't know what they're talking about.....well, you're in for a disappointment.
oh, and if you do decide to stick it out, I'd ask for written confirmation on any Lock-In that you do. If they can't deliver that, I'd run.
