Interesting. I spent a couple of hours last week watching neighbors from hell videos on youtube, that one being the most interesting one.
I bought a home in a nice neighborhood in CA. An island too close to run-down neighborhoods nearby. Don't ever make that mistake! The old families began moving out a few years later and the riff-raff started gradually moving in. Our little island became the shopping mall for the druggies. You could never leave your door unlocked or your garage door open unless you were out there. I eventually got burglarized. Stole everything that meant anything to us.
An investor bought the house next door. Spent at least $50K fixing it up really nice. Then he made it a Section-8 rental. Big mistake. Rented it to an elderly black woman (am I allowed to mention that?) who never moved in but was the renter of record. One of her daughters with a bunch of kids actually moved in. They got the mandatory mean pit bull chained in the back yard, totally neglected with no shelter. Selling drugs was next. Traffic at all hours, gunshots in the street (truth), fights, crazy druggie nephew living in his car out on the street, police raids with occupants running off in all directions. They were finally kind enough to burn half the house down before finally getting kicked out. I actually heard the woman say (while crying), "Why are they doing this to us? We weren't bothering nobody."
Mexicans bought the house on the other side of us. Mexicans are often nice people but, if they are immigrants, they are noisy people. That is something they will admit to. Outdoors (including out on the street) is just another large room of the house when it comes to parties. You better like the mariachi music. Don't bother calling the cops. I called them at 1AM one morning and they showed up at 7AM. My neighbor put his stereo on his patio and played that mariachi music at a moderate level. Problem was, his patio was about 8 feet from my patio, divided by a wooden fence. I hooked up my high-powered stereo system, with huge speakers. I put Michael Jackson's "Beat It" on a loop and turned it up full blast and played it for 2 hours non-stop. You could have heard that 5 blocks away. Nobody called the cops and he knocked off the mariachi music on the patio from that point on. I'll just skip the part about the fighting roosters he kept in his yard for a while.
I toughed it out until I retired and settled out in the desert near Phoenix where I am nowhere near that stuff anymore.
And, oh yeah, STAY OUT OF MY YARD!
Rant over.
