check me out on citihabitats.com
There are many of them online.
The scammers may use real listings, and hijack the photos (if they even post photos) to create fake "listings".
Did anyone ask you to wire money for keys?
Did they tell you they cannot show you the apartment in person because they are out of the area?
If the answer was "yes" to any of those questions.......run in the opposite direction!
