Mold Issue

[Sophia Wang]

I went to look at a potential flip this afternoon. The house is in great shape other than the fact that the whole house is covered in a layer of mold! At first when I step in, I thought it was just dirty, so the floor is covered by dust. Upon further examination, the 'dust' is actually a light layer of mold, and the same mold is on literally every surface, from door, to furniture, to floor...

I am thinking of getting a professional mold mediation company to come by and give a quote. But just want to see if any rehabber here has experience dealing with this kind of mold issue. It doesn't look like it has reached behind the walls, rather, just growing on the surface.
