I spent years working on very old houses, some historically significant. As others have alluded to, it's usually a massive undertaking. From the first photos on this thread, I could tell that this house is worth about negative $100k, (or whatever the cost of demolition and haul-away is around there).
The term, "historically significant" is misused and misunderstood quite a bit. Nearly anything old might be historically significant to someone, (like a person who once lived in the house or whose ancestors did). This does not necessarily translate into being significant to the world at large.
The location alone of this place, in the middle of nowhere in rural Ohio on a farm, means that it would have to be an early FLW house or similar to have any significance and value. It is a fairly ordinary if large and fancy house for the time. It would need to be sitting in Greenwich Village in NYC to be worth reviving. And if it was, the dirt it's sitting on would be worth $50 million and it would be scraped. No sale.
