I live in a townhouse, so neighbors are very close and when you get a bad one, it's tough to deal with.
For about two years we had a horrible family renting next door. These places have 3 to 4 small bedrooms, but that is not enough to accomodate the number of people they had living there... two parents, two grown children, four grade-school kids, two toddlers (one was the daughter's), an infant, and one large, noisy dog.
The oldest boy (somewhere in his 20's) would frequently sit on the stairs out front with his friends, playing loud rap music, talking loudly or fighting and yelling obscenities. The younger kids were always starting fights with the other kids who lived here and were banned from the playground. The deck out back and the surrounding yard was a hideous mess of toys, broken lawn furniture and dog crap (the association would levy fines and make them clean it up periodically, but within days it would be trashed again). They'd leave the dog outside in all weather, whining or barking it's head off. The police were regular visitors, I'd say at least once or twice a week, either because the parents would be fighting, a neighbor called to complain about the noise (I complained to the association, but I never called the cops), or the oldest girl's ex would come around making trouble. Once we came home to several police blocking the street with weapons drawn on the guy.
They finally skipped town one night, and the whole complex breathed a sigh of relief.
