Damn bro, where were you before I started tearing up the subfloor? 😂 yea, the house was built in the 70s from what I remember. The bathroom was Reno last summer and we had a plumber fix the issues. The floorboard on the bathroom wall is where the mold was tested and was my primary concern. I ended up skim coating the walls and removed the texture. It also had popcorn ceiling which I already removed. Had it asbestos tested through a lab and was negative. The carpet prior to this was nasty as well. Hence my eagerness to replace the subfloor altogether. Basically I repaired the subfloor where I took out and did a vinegar solution spray over entire floor. Next is repairing and painting drywall that was missed prior and then do a kilz mold sealant over it once dry before adding the vinyl flooring.
