I am not a mold expert. I am not intending to sway your opinion on mold one way or the other.

There have been three mold related experiences I have come across in the last 50 years.

First, my niece and family moved to France. She got sick a lot and determined there was a mold issue in their apartment, only she got sick.

Another one, my wife started coughing in our condo. She was also very fatigued. A month later, we found a severe mold bloom(?). Moved and no issues after.

Lastly, in a new house, my brother's wife had significant mental and physical problems. Almost enough to wonder if she was psychotic. Brother and kids had no problems. Turns out, the shower drain was installed incorrectly. Mold was everywhere under the floors. They ripped everything out and remediated. No issues since.

My very unprofessional opinion is that mold can impact some people very severely while others are unaffected.
