Significant water damage to the subfloor and framing
Long-term moisture in the crawlspace had water-damaged the subflooring below both the bathrooms and the kitchen, along with the floor framing underneath. The main carrying beam was water-damaged badly enough that the report calls for replacement, and the rim joists and sill plates — the framing the whole house sits on — were water-damaged on both sides of the home.
This is the floor structure of the house quietly rotting from below — the part you stand on, can't see, and can't paint over. It's the single biggest structural issue in the home, it doesn't stop on its own, and it's why the floors didn't feel right underfoot.
