Welcome to BP! I am originally from Southern California and when I first got into the Memphis market I was completely blown away that there were many houses in good condition to buy in the low 20's.
Yes, you can buy houses very cheaply---it may be a pretty nice little house---but the areas they are in can be a problem. I am not saying "Don't Do It!" but it would be a very good idea to do lots of research here using the handy dandy search bar. Do lots of reading on under 30k homes, turnkeys, buying homes in the hood etc.
The most important thing is to have a team in the area you want to buy. Every month I talk to people that are now sellers that bought a few years ago and paid WAY too much, even at 30k, or 15k----I am not kidding or exaggerating. It seems like when sellers see that you are from California they know they have a good chance to take advantage of you.
Now, having said all that, I do like the homes under 30k. But I also have the most wonderful people in my market that give me the straight info on anything I am considering. They keep me from making bad choices that I could later regret.
Best of Success to You
ps. take your time, don't be in a hurry and study much ---> there will always be lots of houses ;-)
