Mortgage RateI am a first time home buyer and I am supposed to close on a house on April 28th. I do not have a rate locked in at this time, and I worry that rates may sky rocket last minute. Also, my mortgage guy told me if my credit score got to a certain number he could get me under 5 but close to 5. Yet, all the paper work for pre approval says 5.375. Is it likely that on the day we try and lock a rate he will try to give us the higher rate?Thank youMarch 08 2011 - Norton00YesReport a ProblemProblemSelect oneOffensive contentIrrelevant contentSpam (pure self-promotion)OtherDetailsYour emailPlease enter a valid email address.Submit CancelContent flaggedWe will review this content.
