I am financing a mortgage 100%(have excellent credit).Would paying off any credit card debt get a better rate?

Doing 100% mortgage financing and have excellent credit rating. Don't carry high credit card balance, but do carry one. Would paying the credit card off get me a better interest rate or would the only help be making a down payment and financing less than 100%?

Paying off your credit card balance is a good thing to do. Yes it will help your FICO score,.

More importantly, you can use refinancing proceeds to pay off the card ( which is -what- at 30% or something like that ) and replace it with a 8% or so rate ( and the interest is Tax-deductible ).

Ask your lender. Typically, it should not make any difference.

What about PMI?? Has anyone mentioned that with a 100% loan you have to pay Personal (primary??) Mortgage Insurance??

Make the down payment, and get a fixed 30 year 1st mortgage only.

Because you have excellent credit already paying off that credit card wouldn't really help you. The only way that would really help you is if you are trying to eliminate some of your monthly bills besides you need to keep at least one thing open on your credit because that's how we get approved for other things. They need to see that you have something on your credit you have been paying on for a while,and you have been paying on it consistently before they will approve you for anything else.
