I always wonder about these abandoned houses too. If the foundation was solid the house can be repaired, believe it or not. They built old houses in such a way that modern houses would never survive, but these are still standing.

From the first picture this house looks very straight (roof lines, wall lines) most of the damage inside looks like water damage with the exception of the fireplace collapse. If a person got it for free it could be fixed, IMO. Solid materials were used in the construction!! Awesome find!
