My neighbours at the house we are renovating are also renovating, and they have more power tools than we do Seems like a nice enough bloke, but he hit our verandah gutters with his caravan (you know a house needs renovating when you have to bring a caravan so you have somewhere to stay while doing it) and then wandered in our *back* door to tell us he'd fix it ...If your works are likely to affect your neighbours in any way - noise, traffic, dust, etc - then make sure you've met them and explained what you're doing before you start, and try to keep them on side.
He paid more for his house, several years before we bought ours, and it is not only a smaller house in worse condition it is also on a block 1/3 the size
