I've been here a couple of times before, but for some reason hadn't been quite convinced it wasn't being used, at least as some kind of hunt camp. I decided to go back out for another look and realized I must have been on crack not to have noticed before.
The entire house has shifted significantly on a broken foundation. Broken is being gentle about it. The entire front side of the foundation has collapsed completely. One of the supports in the basement has slipped and been crumbling out from under the house. Further, all of this has caused the foundation on the side to crack and shift. The second-to-last picture in the gallery is looking down the stairs into the basement.
Inside, the house seems in reasonable shape, if you ignore the fact that nothing is square, and there's a gap of several inches between the floor and the bottom of the wall on one side. Otherwise, it looks like it was once pretty cozy.
