well i have had the neighbours from hell (thankfully they have moved otherwise i would have moved lol) they would call the police if we parked the wrong way near our house, they would yell abuse if we walked anywhere near or past their house, my brother was throwing a ball around and it landed over their fence in there yard and we went over to ask if we could have it back and their daughter retrieved it and once we got home heard the mother yelling abuse at the daughter for giving back!
so yeh i think in some situations i would pay extra to have decent or normal neighbours lol
