Need some advice, In February the house next door sold, and the guy who bought it is renting it out. There is currently 9 people living there all between the ages of 30-40, all Indian nationality (not that it matters), and only 1 has a job. Keep in mind, its a 4 bedroom house. Lately, my neighbor on the other side of me and I have noticed that they will be out wandering, talking on their phone, and walking through both of our backyards. When we catch them we will signal them to get off our property but I don't think they get the hint. What should I do? I don't think talking to the landlord will help, as we are currently fighting with the city because they wont mow their lawn and they keep making up excuses on why they cant get their mower over there.
