REO Occupied Question

[Mike Selander]

I found a listing with the following disclaimer on Hudzu:

REO Occupied - the seller does not represent or guarantee occupancy status. NO VIEWINGS of this property. Please DO NOT DISTURB the occupant. "As is" cash only sale with no contingencies or inspections. Buyer will be responsible for obtaining possession of the property upon closing.

So I have no idea if the occupant has a lease or what the monthly rent is. I can not see the inside, but the outside looks like it is in fairly good shape. This make me nervous. Any advise from more experienced investors?
