There are at-least 2 good books on house-inspecting.

( looking … dayum, there’s zillions of books on it, now… )

www.amazon.com/…/1561584622/

is the one I invested-in, years ago ( not to do house-inspection, just to learn the competence of it )

Please invest in that book, or an equivalent to it, and make your own inspection of the house, 1st.

Then you’ll have much better understanding of the entire subject.
