What qualificiations do you need in order to rent an apartment?

I will be turning 18 in July, and need to move out my house. My mother agreed to be my co-signer, and I currently work as a Legal Secretary so the matter of income is not a problem. Do you think that even though I am of a young age, and I don't have bad credit... I just don't have any credit (hah), that I will have a terribly hard time finding an apartment to rent?
