That's such a shame It sounded like such an amazing place, maybe you'll be lucky and find something just as great elsewhere?

Oh man. That is too much work for a "new" house.

The sellers aren't willing to negotiate on repair costs? Usually when problems are found at inspection you should be able to get the previous owner to pay for some of it since you would be taking over problems that weren't fully disclosed.

Or just live with the maintenance issues. Its not like its getting freeze thaw cycles and 10 inches of rain a month.
My first house the basement leaked so bad there were asphalt mounds acting as a ditch all around the wall, the water would run into this and out a drain that ran into a ditch. It was so wet frogs lived in it year round. It had been like that for 80 years and i bet it will still be that way for another 80. Everyone thought is was very charming to hear water running, and because of the frogs i never once saw a spider in the house.
Guess it depends what your able to compromise.

Anything foundation or slab scares the crud outta me.

Sounds like a wise move. It's one thing if you got the place for free or close to it, but if you're paying anywhere near market value there is no case to be made for a place with multiple expensive and complex structural issues, especially in this market.
