Lots of scams, so be careful. I wrote a blog about it awhile ago. Scammers are becoming more sophisticated; a real estate professional who actiely works with rental and homes for purchases will be able to tell you what is a scam. If you know the areas you are looking is "really cheap" compared to other homes available, be careful. Do these ads have a phone number to call? If the person picking the phone "has no clue" or the information does not match, those are also red flags. I will not divulge too much here because scammers could be reading.
