My first paid inspection was about as easy as they come. First year home warranty, and the owner already had a list of things needing done. They selected me because of my past GC experience, and picked my brain regarding some improvements they were considering.
I own several rent houses, so had done several mock inspections, and also had a few local inspectors let me ride along with them on several inspections.
Did I miss a lot of things? How would I know?
I am convinced that we all miss stuff on a regular basis, either because we get complacent, distracted, or miss some tell-tale sign. It is definitely a must to have a checklist, either on your portable device or on paper. “Keep” is the resident note-taking app on my Android phone, and it allows you to make checklists. Highly recommended.
