If you're doing the work yourself, this will move at the speed of you. However, if you're working with a contractor, for the most part, your timeline is not going to go on a "room by room" basis. It will go as a per project basis. For example, for us and Beverly, we had HVAC, then we had electrical, then we had plumbing (with a bit of overlap between the 2), then we had drywall, etc. With good contractors, bigger things like electrical, HVAC, plumbing can be done anywhere from a few days to a couple weeks. It really depends on how big the house is that you have and also how in depth your work needs to be. Changing out a few outlets is going to take significantly less time than rewiring a whole entire house.
