For my house, I bought one of those 360 cameras, Rico Theta something, it is about 3 years old, and took pics through out the remodel. There is free software to set those up like a 3D house tour, although not as flashy. I did that a few different points in time, but having the pics annotated to be searchable by room name or "wiring" or "duct" is more helpful.

The 360 camera was hugely helpful because I could take one picture of a room instead of 5-15. I could walk through 3K square feet and take pics of everything in about 15 minutes.
