Devils Dumplings what a nightmare situation. Your neighbours sound nasty and totally bonkers. You sound nice and have tried to be good neighbours only for it to be seen as a sign of weakness. My first reaction was 'theres something more going on here' by which I mean jealousy or a very real attempt to drive down the value of your property for the benefit of themselves or a relative. Yes, the previous vendors should have declared the problem it's a legal requirement. However, should have doesn't always happen as we know to our cost. Our vendors failed to declare the arson attempt, windscreen breaking, missile throwing!!! In fact in answer to my direct question about the nearby small park they declared never a hint of bother!! It was a neighbour who told us the details 2 years after we moved in. We had to get our local pcso involved and he was great as he had local knowledge and I can now sleep at night, we didn't want an expensive legal battle. But it did get me down very badly. I don't think any more reasoning from yourselves will help. You must feel stuck & cheated. Are there any locals e.g. local newsagents,grocers etc who can throw any light on their behaviour, are they known to police for anti social behaviour, can you check back issues of local paper. Are they dead set against 'incomers'. I agree with others that recommend telling your tradesmen that they're " plain bonkers & well known for it in these parts". Keep making the records, time, date, duration, who etc, whether you spoke & what was said. Try and get recordings of photo evidence, if it's photo make sure your date/time function is on. Get advice, assertive and Wiley, sooner or later they will do something that requires a little knock & some plain speaking from the boys in blue. It's like a game to them - bide your time but gather info & evidence but don't let this ruin your lives. It's feeling so impotent that wears you out. Wishing you all very best.
