house hunting... creepy

So the wife and I went house hunting today. (just as we did last weekend)
we are looking for a place in a Dallas suburb that will hopefully put me closer to my work, and will provide her with greater opportunities when she finally finishes her degree late this year.
we couldnt resist looking at this massive foreclosed home valued at about $200K but priced in the 130's
i kinda figured the place would be a wreck, but it wasn't that bad. It needed paint inside in a couple of rooms, and the carpet needed to be steam cleaned or completely replaced, but it was a huge house for a small house price.
one creepy thing that caught my eye however...
each of the children's bed rooms had those hotel style "door chains" on the OUTSIDE of the doors. meaning they would serve only to keep a person locked INSIDE the room. :-?
what the heck is up with that?!
