I am about to buy my first house. Inspection went great with one possible exception, which I am worried about (but maybe shouldn't be?). The original inspector mentioned that the interior linen closet and one of the bedroom closets (which shares a wall with the linen closet) have some spots towards the top (near the ceiling but not on the ceiling itself) that look like some kind of fungus, perhaps mold. The door is pretty airtight, so circulation is not good. He said he didn't think it was anything to worry about. He recommended shaving an inch or two off the bottom of the door to improve circulation, spraying the infected area with an anti-fungal agent, and then repainting. He said the fungus did not go past the paint level (i.e. into the drywall). I had a mold expert come out just to look at it, and he agreed with the inspector's opinion, although we did not order any mold tests nor rip out any drywall to look behind. Both inspectors did go up into the attic to look above the closets and did not see any mold. Same story with the crawl space and other parts of the house - no signs of mold.
My theory is that perhaps at some point, before the new roof was put on, there was a leak that caused some growth. Alternatively, perhaps due to the lack of circulation, slowly but surely there was just a tiny bit of moisture buildup over time that manifested into the perceived problem I see today.
FYI: The house I am buying has a crawl space with low-normal humidity levels and a relatively new roof (so no recent leaks). The sellers are willing to pay for the repairs.
Am I freaking out for a dumb reason? I just hear the word mold/fungus and go into panic mode, even though I know every house has mold, especially here in the Southeast. 1 expert, 1 inspector, and 1 contractor have expressed their opinion that it is a non-issue. If you were a homebuyer, would you take further steps to address the situation? Or heed the advice (stop worrying, shave the door to improve circulation, kill the fungus, and repaint) of everyone around you?
EDIT: I meant bedroom closet, not bathroom closet as originally posted.
