How do you spot bad neighbours when buying a house?

What’s their property like? Does it need any maintenance? Is there any rubbish lying around? Do they have a vehicle that’s in good shape? Is there a fence on their side that needs maintaining? Try to inspect the property at different times like at the weekend or on an evening. If you can hear, see or smell something that wasn’t present when you were shown the property, that’s probably a bit of a giveaway. Of course, each person has their own set of circumstances that might prevent them from maintenance work. If you’re feeling brave, you could always feign a favour and knock the door to meet them. How friendly are they in assisting you with your request? Of course, all could be well until you move in. They’ve been living next to a nice quiet house for a while and they might react negatively to your presence. It might be you that’s the bad neighbour…
