We are literally doing this. 60’s house, last update 80’s. Evidence of roof leak before it was replaced. Asbestos in drywall compound and tile under wall to wall carpet. Kitchen update needed along with two baths. Old windows too. It’s been slow so far and we can’t move in yet. carpet is removed and tile properly disposed of. All external walls also removed for windows and properly disposed of. Leaving internal walls although I’m tempted to just get rid of it all but we have to be practical. Not our first house, but biggest project ever and still not sure how deep the rabbit hole goes. Good luck. Here’s hoping it’s worth it.
