check out this you tube video about the problem; http://www.pickrent.com/videos/rentalscams/
I am the listing agent for this property and, yes, someone has copied my pictures and is running a rental scam on Craig's List!! These people operate from utside the US and there's really no way to stop them!!
Basically these people will try and get you to send them a certified check in England or something. They will tell you that they can show you the unit, and then will say, "Oh my brother can't make it but if you agree to take it without looking at it, we'll knock off $300 a month" or some such thing!
Don't send then ANYTHING!!
Hope this clears it up!
