One house had a Harley Davidson motorcycle parked in the living room, dripping oil on the carpet.
Another had fiberglass insulation batting over the bedroom windows.
Another was a rental, shown by appointment, and it was clear they had spread clothing and stuff all over to discourage anyone from making an offer, and the renters were there and made it clear they were not happy that they may have to move.
And the one we bought, had wrought iron bars on ALL the windows. Bolted on with one way bolts, no interior released in case of fire. We ALMOST didn't go inside, and that would have been a mistake. Older couple.......ironically about the same age we are now. EVERYTHING inside was wrought iron. Book cases, coffee table, dining room table, headboards on all the beds. They were wrought iron fanatics. That was over 40 years ago, day we took possession of the house, I was out with a file and vice grips removing the wrought iron bars while the alarm company guy installed the alarm. I made a LOT of friends that day on the street by taking down those bars.
