Our house in Pensacola...while we were still living in it....
The house across the street from us was owned by a guy who worked in Saudi Arabia. He had a property manager that did nothing as to taking care of the house, as far as I could tell. The tenants had someone living in the garage. When the garage door was open, you could see a bedroom suite set up in the garage --a put together, made up bed with a dresser, etc. And there was often people lounging around in the garage as if it were a living area of the house. I've never seen anything like it. My husband was in our garage one day and came inside and told me that the people who "lived in the garage" across the street were making out in it with the garage door open! Well, dang, it was hot in there, so I could see why they'd leave the door open to make out. lol. It wasn't so funny at the time, though.
I also think the tenants were selling drugs out of the house. We'd see multiple cars come and go from the house from late afternoon into the late evening hours. Eventually the lease was up or the tenants were kicked out...and the house was left a mess. The owner had put a lot of money into the place before he went overseas and the tenants had trashed the place.
**Oh and this house was not in what you would think would be a bad or drug-house type area. It was a quiet, middle class neighborhood. At the time, as I recall, average rent in the neighborhood was around $750- $800 or so a month. This was around 25 years ago. So it wasn't exactly a cheap rental house, but then again, I am not sure how many people the tenants had sublet to "live" in the house and garage.
