"They will be condemned for black mold instantly. "

Anyone with deep pockets will be a target of the vultures and a financially disadvantaged populace. Think on the bright side, they're going to need to build entire subdivisions for the hordes of lawyers that are going to descend upon NOLA.
You were lucky!
