Is this log cabin worth fixing up?

Douglas fir. 50 yrs old. dry climate in quesnel bc. most of the foundation logs are not rotten. rotten at corners. most of the rot seems to be caused by lousy roof.

The roof is definitely thrashed. You'll most likely have to rip it down to the rafters as the roof boards are probably rotting. Do you have any pics of the underside of the roof (from inside the attic)?

Saveable??? Sure, depending on your budget. How much are you willing to spend?

I would say if you like it then save it and fix it up, I have seen a lot worse then that.
