Based on all the comments here, I am definitely going to leave selling our home place to my kids, after I'm dead. I have personally done 100% of the plumbing, at least half of the construction, and way more than half of the electrical wiring on our farm, including the main house, since I started building it 40 years ago (before any kind of building permit was required here, for anything). The septic systems have of course been professionally constructed and inspected, and I've gotten permits and inspections on the electrical where it was required (really only for service entry builds) but overall, most of the place is owner built and maintained. I'm guessing, from what I'm reading here, and my experience selling my parents' almost new home across the state line, that realtors and inspectors are going to have a field day when this place moves.
