I’m unaware of any obligation a renter has to stay in a neighborhood no matter who will move if in if he leaves but it’s not so simple in Halacha for a homeowner to sell his house in a changing neighborhood and cause further deterioration.
Obviously there are many factors involved and this is beyond a coffee room discussion but from the viewpoint of Halacha it isn’t simple to tell people just sell your house and too bad on those who can’t move
