I invest in this price point. I also have been looking in Alabama. It is very possible to make money in this class of property but you MUST do your due diligence regarding the neighborhoods and the rental market. Find locals who know the city and neighborhoods you are interested in and work with them. If you can't, don't bother. Stay out of war zones - you will make a ton of money and then give it all back. Ask me how I know...
Make sure it's at least a C-class neighborhood and be open to section 8 vouchers. Make ABSOLUTELY SURE you have a worthy property management company behind you. It's not going to be easy because the PM business is a very tough one, but a good one is worth their weight in gold. If you can't find one - don't bother and move on to a different market or area. I have not pulled the trigger in Alabama because I have not been able to meet these basics as of yet.
The Cleveland/Akron market offers these properties also. Lot's of neighborhoods that people think are horrible that offer nice opportunity.
Good luck and keep us posted!
