@Adrienne G.,
FHA is usually the best option for people with shaky credit, as it only requires 3.5% down + closing costs, which I believe CC can be factored into the loan. The only snag I think you will run into is the history of employment, so that may only be of help in the future.
As far as no money down goes, it is real but you have to find an investor and be able to prove to them that you can make them money with the money they are giving you. Which is very possible if you do your networking and learn what a good deal is, you can learn how to do on BP! You just have to be able to show them.
I really wish I had a "here's your solution!" answer to help you out, but I too am a newbie and I'm just trying to relay what I've picked up so far that may apply. Like @Paul Timmins said local REI clubs are a great start for information and networking with people who know the area. All you have to do is meet that one right person and it could change everything for you!
Keep researching and asking questions and you'll figure out which options you can make happen and how! Sending good vibes your way! Welcome and Good luck!
