I have a family member who's law enforcement. They said they get calls where the "caller" hangs up when the phone is answered, so they go out to the address but it's an address where the house burned down or where a tragedy happened and no one lives there anymore. And apparently it happens often.

Not paranormal but apparently sometimes people commit suicide and the family will come to the site and they just talk about wanting an inheritance and not even caring that a family member committed suicide.

  No comment on the first part..... But the second part of your post happens with murders as well. In 2015 my sister was shot to death by her husband, in my town the police only take the body and pertinent evidence, the city does not pay for clean up if it happens on private property and we couldn't afford $4500 to pay a service. So while cleaning up not only all the crap in the house, but also a blood and gore spattered laundry room, i had to deal with her kid's (ones that were exerting no effort to help mind you,OR expressing anything like grief) demand "sentimental" (and expensive) belongings, money etc., AND the murderer’s family making similar demands, AND the tweaker roommate demanding the same things. I let her oldest (who was actually helping) claim a couch and random bits,i took a TV stand,love seat,a nice cookware set,family photos,and her angel necklace which now adorns my biker jacket (where most small sentimental objects end up) I also claimed his knife collection. We sold anything of value to pay expenses,burned everything he owned on his BBQ then smashed it,and when we finally let his rather belligerent family take his truck we'd stuffed the linoleum and paneling we had to tear out of the laundry room, plus the ashes of his belongings in the cab and broke the locks, it was august so i'm sure they enjoyed that. Were we asholes? yeah, but i feel justified, if anyone disagrees i don't care.
  Sorry, got triggered,and had to
  post is already long but yes there was a paranormal aspect i believe, so yeah i feel this belongs here, someone remind me later and i'll write that up
