Found some spots in the closet in a musty smelling finished basement in-law apartment that showed up when I took a picture with the flash on, but don't seem very visible during the daylight. This closet shares the wall with the bathroom; all the clothes in it smell musty, too. The unit has a dehumidifier, but that doesn't eliminate the musty smell. Been living here a week; day 4 began dry coughing, day 6 had serious sinus issues, dizziness, lymph pain day 7 once it began raining. The place seemed well taken care of, but that doesn't mean there aren't other issues. Yellow mold? What do you think? Click to Enlarge 61.02 KB
