Thank you all for your words of encouragement and words of caution. I went back over last night and took a better look in the crawl space. I dug the crushed rock out from under the sill plate and found daylight. Then I thought, surely they must have put piers down in the corners and every 8' or so, so I crawled over to the corner and same thing, nothing but wood sill plate sitting on crushed rock. I live on the Iron Range and they moved the town starting around 1920 so that they could mine underneath where the town currently sat. This may be one of the houses that they moved. Whoever moved it obviously did not worry about doing it correctly
@Alex Franks I understand where you are coming from but the idea that is bouncing around in my head is that the folks that couldn't normally afford to rent a 3/2 with a two stall garage and large lot on the edge of town would love to rent this for $150 or so below market rent. It would not be perfect, but theoretically, it would be safe and secure. (of course, in this example, it is not so safe and secure.)
Maybe my thinking is flawed on this issue. What do you guys think?
