So - we are walking further down the path of doing a major renovation to our house. Looking for some input from Bees who have been down that path...

(project scope: extend back wall for 2/3 of the house - pushing it 15', completely re-do kitchen, master bath & back hall/mud room, add 3rd stall garage & raise garage roof line for second floor living space including roughed in plumbing for a bath)

My questions are:

1) Did you move out for all or part of the Reno? If so how did that work?
2) Did you pay cash? Borrow? Or some combination?
3) Did you use a project manager in addition to a GC?
4) Did you use an interior decorator/designer?

TIA!
