answer: #Person1# signs a one-year lease with #Person2# and tells #Person2# #Person2#'ll get the security deposit back if everything's alright.
documents: #Person1#: Everything seems to be OK, but how long do you want the place?
  #Person2#: Six months.
  #Person1#: Oh well, that might be a problem. I only sign one-year lease.
  #Person2#: Well, one year would be fine, too. I'm not planning on leaving the area soon.
  #Person1#: Well if it's not a problem, then here you go.
  #Person2#: Just let me look at it quickly.
  #Person1#: Of course.
  #Person2#: It seems to be a standard lease.
  #Person1#: Yeah, and don't worry about the security deposit. If everything's alright when you move out, you get it back.
  #Person2#: Great, just sign and date it here.
  #Person1#: Yes, thanks, you can move in tomorrow.
  #Person2#: Wonderful!
