Fire damage--remove and replace; smoke damage--clean and deodorize (keep in mind that pretty much everything in the same airspace will have some measure of smoke contamination--this even includes the HVAC ductwork) ; water damage--mitigate and dry out (but if its remained wet for a period of time you might be looking at mold--remove and replace).

Drainage is normally easy to address-extend the downspouts on the gutters, move the soil to change the grade, add a drain. 

So becoming a loan signing agent, I actually did use the NNA course and it was a little dry but had a lot of helpful information to it.

It's not the most exciting thing in the world, its actually quite dry.

K&T wasn’t necessarily dangerous when it was being installed and was phased out for cost reasons not safety reasons, but the fact that it is now 80 plus years old, and most likely has splices in it done by who knows who, and bigger loads on it than it was intended for, original fuses replaced with modern fuses meant for higher loads, the cloth and rubber insulation has likely dried out and become brittle, cracked and been chewed on by vermin... all that means it has a high likelihood of being dangerous today or at the very least insufficient to handle modern day electric loads.

I hate operating like that as it becomes a big waste of time for a lot of people but I would rather disappoint some lenders than get hung out to dry or forced to accept a deal that is sub par.  

East Fayetteville is great as well with top notch schools you just need to be on the look out for foundation issues as a lot of those houses are built on rocky soil. 

See the closest hill to town, all rock and soil.  

(Always bring a flashlight and take a close look) The previous owner was throwing junk down there and there was some dry rot on the sills, nothing too serious but it could have been a lot worse.

Walk the land and see if it looks dry then check with the town planning department and figure out what they will allow.
