I used to think due diligence stopped at the property line. Soil tests, well logs, title search — check every box and you're protected. Bought 80 acres in 2009 and did everything right on paper. What I didn't do was ask around about the operation next door.
Turns out my new neighbor ran a feedlot with drainage that crept toward my low ground every wet spring. Wasn't illegal, wasn't disclosed, wasn't visible during my summer walkthrough. Cost me two hay cuttings and a nasty fence dispute before I got it sorted.
Now I spend half a day driving section roads before I ever make an offer. I stop at the co-op, I talk to whoever's checking anhydrous tanks, I find the nearest FSA office and ask casual questions. Rural communities talk. You can learn more about a neighbor's reputation for boundary respect, chemical drift habits, and water management in one afternoon than any inspector will ever put in a report.
Anybody else factor in neighbor due diligence, or do most buyers still treat it like an afterthought?
