Golden Rule
The best thing you can do is follow the golden rule of being a good neighbor. Treat your neighbors with respect and keep your distance, avoid spreading neighborhood gossip, and try whenever you can to work through issues quickly and directly with those involved.
Curb Appeal
Of course, especially when you’re living in a neighborhood, keeping your home maintained can help avoid unpleasant confrontations as well. At the very least, you can keep your home at the same level as the surrounding homes, that way everything is uniform and nobody can get upset that something is sticking out.
