Can I get any apartment with a co signer?

There’s an apartment I really want in downtown and it’s really close to the cc I will be going to.

I’ve been saving a years worth of income so I won’t ever miss a payment/rent etc, problem is I’ve been told I’d need a good credit score but I don’t have any. I’m 21. So if I got a co signer for the apartment would I be able to get it? Thanks!
