Getting a loan for first time house buyer

I have been thinking about this for awhile, but Im about 3 to 4 years out on getting my first house.

As far as credit goes.
I have had a credit card for two years that I have never missed a payment, and I always pay off every month. I get my experian score every quarter and its mid 700's. My CC company just uped my limit, almost 11 times more then I originally had.

My question is, with a good down payment (25%+)and good income can I qualify add excellant mortgage rates with just a CC on my credit report?
