Best source for dilapidated building/acreage?

[John Bergstrom]

Earlier this year I came across a 9ac rural ag parcel where a tornado had knocked down outbuildings, but the old farmhouse, grain bins, garage etc were all still standing (but the house was a raze candidate). Long story short- I offered ask but the seller went with someone else (same amount but a local). Am struggling with my searches now- Where do I find small acreage parcels with or without buildings or with buildings in need of rehab? Do counties track these? Other realty sites? (The realtors are asking insane prices, or don’t have any listings.) There has to be some methodology for finding that old abandoned farmland/house that is wasting away that I can refurb. Ideas?
