If the housing camp crops up after you buy your house, sell it for what it's worth and move. Deal with your problems yourself, don't expect the government to come to help you.

I want you to think: What happens when everyone shares the attitude you just put forward? What happens when we can't open any homeless shelters because everyone gets angry and tries their best to constantly shut them down? We don't get more shelters, we don't fix the problem, poverty gets worse, the homeless get more desperate, and everyone loses.

just move!

Yes, sell your house and move. Should we solve your problems without putting in an ounce of work? It's hard work to move, yeah. However, you've got a problem. You fix the problem. If you don't want to fix the problem, don't go complaining to everyone about how bad the problem is.

You bought the house where housing was so messed up that the homeless are literally building camps by the sides of the road. If you wanted to, you could have probably been part of the political system that allowed or prevented it to go up in the first place. You might have been able to put more regulations on the number of homeless allowed in the area, or pushed for a corresponding increase in police forces to compensate. However, I'm guessing you weren't part of that either.
