There are a lot of scams on houses like this. Beware of who you are dealing with. People are misrepresenting themselves as the owner of the property, the property manager, friend of the owner, etc. Many people have paid up front rents for properties and then found out that they were scammed.
Do a little research of your own. Knock on the door of one or more of the neighbors and ask if they know anything about the house. Look the property up in the county tax records to see who really owns it. Call the owner of record and ask them questions.
Good luck. If it's really for rent for such a low price it sounds like a good deal.
