Is there any data on home values decreasing due to proximity to factory farms?

I have not read anything like that except from organizations that are trying to scare people into eliminating factory farms altogether like in this link here. Farming is part of American culture and there are right ways to do it and wrong ways to do it. The main people that want to eliminate farming have never farmed and many do not eat meat. That is their choice, but I vote for healthy sustainable farming instead of eliminating options for farmers with scare tactics. That's just my opinion though.
