My lovely neighbour lives in a semi, both privately owned from moment they were built. She is being driven potty by her neighbours, noise, dogs and building works going over the property line. My MIL in law has had the same problems which her own, privately owning, neighbours over the years.
On our nice, small, entirely privately owned estate there are two noisy dogs, a man who likes to scream abuse at one of the dogs over the fence when the owners are out, someone who keeps complaining to the council about everyone and everything (park more than two vehicles on your drive? Must be running a dodgy car business), a phantom weedkiller, a revy boy racer, and a teenager who likes to lurk on corners being intimidating (he thinks), with his friends, in hoodies. I grew up on a council estate, it was tame by comparison.
The point being, your neighbours could be lovely, they could be fiends from hell, you don't know (do you know anyone in the area? Could you find out?). Even if you bought a house next to one that was owned, there is no guarantee that the neighbours will remain there forever.
