Lots of crap!
In fact, it looks a little like some of those houses on "Hoarding: Buried Alive". Granted, it's not filled to the ceiling like those, but more like every closet and storage space opened up and puked all the clothes and other contents onto the floor. Mental note: bring a scoop shovel!
That's an old piano on the left and stacked cardboard on the right. The hot-cold cycles of an empty house have caused every piece of wallpaper to start flaking off. That's a good thing because we'll be able to get the walls cleaned up quickly.
And then there's the original trim that is all there except for the stair railing and spindles and the fireplace mantels.
Yes, it's a mess. And, yes, there's a hole in the roof around the chimney. But the house has empty for more than 10 years and we were expecting much, MUCH worse. The basement floor is concrete and the foundation is in great shape.
