To the OP: Do you happen to live on the other side of my neighbors? This sounds all too familiar.
(RANT TIME!!!)
We live in a rural suburb way south of Boston, MA. It's kinda nice, but not ritzy at all, and we moved here just about 4 years ago. We have been at war with our stupid old bags of E36 M3 neighbors pretty much since we moved in. The first time they came over to talk to us, they tried to set "neighborhood rules" with us. They asked us to be quiet after 9pm because that's when they go to sleep, to make sure to keep our lawn and yard mowed, to make sure to never use our patio's built-in fire pit, and to make sure that we take care of the property on our side of their fence. Mind you, our neighborhood is the furthest thing from a HOA... we live in the country! They cited that the former inhabitants of our house, which was a former rental, were loud and obnoxious, so we better not be like them. Every time they are outside and we are, they complain about some mundane thing that we are or aren't doing, and talk down to us. The real trouble with them started last year.
We had a strong storm come through and a tree WAY back on our property came down and smashed their already-mangled (previously hit by another tree and rusty) old chain link fence at the very back corner of their property. According to MA law, it is not up to us to pay for the fence; it is up to the insurance company of the owner of the fence, as it is covered by their insurance policy. Being nice neighbors, we attempted for TWO WEEKS to go and talk to them and maybe help them out with the cost, but they were never home. We gave up and moved on with our lives.
Later that month, I was out working on my truck, and one of them comes over to me and starts giving me a hard time, and telling me how disappointed they are with us. I told him that we tried going over there and they were never home. He didn't care and kept the attitude rolling, and I pretty much told them that I wasn't responsible and if he's gonna pull that attitude with me over a tree smashing his previously smashed fence that he could go berkeley off. By law, it's not my damn problem. Since then, he has nitpicked EVERYTHING we do to the point that I don't want to be outside when they are.
This past March, my wife and I adopted a dog. She is a 2 year old Pit/Shepherd mix (maybe, according to the shelter) and she has been a great dog. We were playing with her out in the yard, and she saw my neighbor and barked. That prompted him to immediately come over and tell me that he is not going to put up with our dog barking at him when he is outside. I told him that she is a DOG and that's what they do. She is not breaking any laws, and he can deal with it.
A month ago, they came over and informed us that we are encroaching on their property because my Trans Am which was parked on my driveway was partially over their property line and they want it moved so they can clean their side of the fence (which I have been doing for the past 4 years). Fair enough, I moved it, but they kept complaining. They came storming over with surveyed property plans and everything, and showed us that their property extended into the middle of our driveway. That resulted in a 2 hour debacle with the female neighbor stating that she will block any renovations we try to do to our house, including the renovation of my garage that is on the property line, because it's an eye sore to them. State and town law dictates that the building is grandfathered in and can be renovated without issue, so they can go to hell. My theory is that I think they wanted to buy the property and knock everything down, but we swooped in and bought it before they could, so they are all butt hurt over it. Also, all vegetation on "my" property at the border of their property has not been trimmed or touched since they started this BS. Wall of weeds FTW.
Part of me wants to just move, as the house was only ever supposed to be a starter house and really isn't what either my wife and I ultimately want, but another more troll-like part of me wants to stay, renovate everything to our liking (and to their dismay), and throw ragers until 2am every night for eternity.
