Thanks guys for the input. I talked with the local electrical inspector the other day, and from our conversation, he is very comfortable with my thoughts and plans. Since it has a newer service, and basically fishing anything new in will be pretty simple because the basement has suspended ceiling tiles in 75% (the rest is open), the attic is straight forward and already has a new grounded cable going through and down a bedroom wall for a computer plug.I can basically use that run alone for 3 bedroom lights, and 3 plug outlets per room.All 3 switches can be accessed/fished easily, the tougher run will be the main floor, but again, because of the upper bathroom location, and having a good size hole in the floor from recent plumbing upgrades, I can fish to the dining room light, kitchen light, and the switches easily, before covering the floor back in.
We talked about the K&T, and because I have a definate white and black lead( hot and neutral), it makes it easier to work with. The difficulty level is pretty low on this one, just more time and patience, which is a good thing!
