1. Let's say it is a complicated, large, old house, like a 125 year old Victorian in San Francisco that has had numerous updates or. a 3500 sf 100+year old Craftsman up in the North Bay. Then I would probably go through then entire house with a GoPro and take a video of everything , each room 360 degrees - just in case I miss something in the photos. Same outside - try to get every thing.
2 Then I would go through the house floor by floor in. a consistent direction e.g. clockwise, taking photos. Use a flash always to bring out true colors. But a tripod helps too, to help get high res photo without blur. Ensure good photos of sinks, cabinets and below sinks. Engage in overkill taking photos of hallways and stairs - because they are connection points. (Same with measurements).
3. Exterior photos, Front, back and each side, as well as street - each direction. Photos of crawlspace and attic.
4. Drone for roof and side photos: Straight overhead, then 45% above the roof, back, front and sides. Especially older homes that have not been well maintained - get 2nd floor eaves, decks, etc..
5. Then I would do measurements exterior and then interior.
6. For FHA - you should have a checklist for what they need in addition to the above. Same for all FM and lender guideline issues.
7. Review inspection of Windows and Doors for signs of dry rot and or water leakage.
8. Look for signs of water problems and/or mold everywhere.
Checklists are good - except if you have a lot work to do, you need to be concerned with workflow and efficiency. You need a pattern of work that fits the house - and ordinary checklists are generally too rigid. But have a general purpose one and review it before you take off just to help make sure you didn't forget anything.
