If you ' re actually looking for a real answer . I ' ve got some experience from 20 years of renting and owning houses . As long as you haven ' t burned any bridges , the most effective tactic I ' ve found seems to be to play Mr . Nice Guy . Drop off a 6 pack and tell them you had an extra , see if they want to come over to grab some BBQ , etc . You ' re not letting them take advantage of you you ' re scheming and getting yourself leverage where you can walk over at 3 am and tell them to knock it off . Play the part of Frank Underwood to get what you want and get leverage over the situation , rather than just sit there and be a victim . This is sort of like that saying hold your friends close but your enemies closer . If they ' re being noisy all the time , or if you call in your favors and it doesn ' t work , you ' re pretty much screwed and it ' s time to start ignoring it or looking at moving . The good thing is the sociopaths who make life hell for their neighbors usually don ' t last long before ending up in foreclosure or eviction , since that lifestyle isn ' t sustainable . I ' ve found those kinds of people burn out in about 12 years and are gone . Dealing with cops won ' t do a damn thing . the cops will do nothing but give them an endless series of warnings , and the residents will figure out who ' s calling the cops and chances are they ' ll start being passiveaggressive and escalating things . About the only way that calling the cops will work is if you ' re in an HOA or if there ' s drugrelated activity going on there , unlicensed daycare , etc .
