Quit Claim Deed

The house I live in now was bought in a survivorship with my father, my mother and myself. My mother passed away, which left my father and I 1/2 owners of the house. He has since signed a quit claim deed on the house 1 1/2 years ago over to me. The house was purchased for $336,000. I have 2 questions: 1) Do I have to pay any capital gains taxes on this house due to the quit claim deed since I didn't pay for the house in the first place? 2) If I sell the house for $335,000, will I have to pay capital gains on the house? There is no mortgage on the house. Kelley
