The listing says 66% of the land is woods, don't plan on leasing that out for hay without a lot of work.
It will likely need a new roof, just from what I can see in the low res pics on the listing.
Houses that old rarely have the amount of insulation we are used to nowadays, be prepared to gut it and install totally new.
Likely needs totally new wiring.
I can't tell if it is the angle of the camera or not, but there is a chance of having foundation issues.
New windows.
Probably new to just massive updates in the plumbing.
It all depends on how long it has sat empty, what (if any) updates have been done throughout the years, and how hard you are willing to work. Your 40k house will, in the end, cost you a lot more than just 40k.
So sayeth your friendly geotechnical geologist (I deal with foundations)
