There are no houses that nice in Camden, NJ
There may be some passably OK houses in Camden, but there is no neighborhood or house as nice as the one they visited in Camden, NJ. It looks more like something you would see in Haddonfield, Merchantville, or Cherry Hill (or perhaps a suburb of LA), but Camden is an economically depressed area. Even where people have the means to keep their homes and properties well-manicured, you won't see properties like that.
Still loved the movie. :)
