I am offering a set of "A practical guide to inspecting", volumes 1-7 which include, Structure, Exteriors, Roofs, Plumbing, Electrical, Heating & Cooling and Interiors. They are in great condition, actually look brand new. You can get an idea of what they are here, http://www.ahit.com/products/books/bp_guides.htm
