This is one for the kooky bin, that's for sure.
We walked into a house in Cocoa Beach FL one Sunday morning. It had a For Sale sign and it looked abandoned and we peeked in the windows and walked around the yard,,and since it looked empty, we decided to see if it was, so we turned the knob on the door and it opened and we took two or three steps inside and realized someone's clothes were laying on the floor.......it wasn't abandoned!
We turned around and got the hell out of there and were terrified we were going to get arrested,,,,it was an honest mistake. This woman, has got to be mentally ill.
I'd be willing to bet that the house you went to look at was being occupied by a squatter.
When we came to look at the house where we live now it was listed by a realtor, and had supposedly been vacant for a few weeks. We arranged an appointment to see the house (since it's quite remote), and when we drove up there was smoke coming from the chimney. At first we thought "how nice of the realtor", only to find a couple of young kids (early 20s) happily living in the house while they made drugs. Turns out that the listing agent had told them the house was empty, and would be for some time. She was fired that day.
