Tricks in your treats

Parents are warned to examine their children's Halloween candy for needles, blades, and drugs, but I wasn't prepared for real estate advertising:

This is:

1. Leftover promotional candy from work that the person gave out on Halloween
2. A brilliantly insane ad campaign, because the people receiving the candy cannot actually buy real estate (granted, their parents should see it)
3. Unintentionally hilarious because I keep seeing two "t"'s instead of "rt" in the surname
4. Some combination of all of the above

 I vote for #4.
