Roof age and condition: Create a visual checklist to use during a showing for signs of moisture intrusion or past/active leaks and make every attempt to gain access to attic/roof sheathing.

The leak was verified visually, or a moisture meter read above the recommended dry range of 14%.

You need to get rid of the drywall since it's porous and holds in a lot of moisture.

The windows were probably just closed for a while and moisture built up in the house.

The duplex needs a new roof, new windows, update with the electrical outlet, it has termites and moisture damage (possibly molds) among some other things.

Where did the moisture come from?

I am still having the mold remediation company (small local private firm) come out just to do some "exploratory" testing to help identify an area of moisture (if any) because the previous air sampling was only a 2 sample (one interior, one exterior.)

The house doesn't feel like it has significant moisture inside; I verified the dryer and bathroom van vent correctly.

There are probably THOUSANDS of strains of mold.All that being said, mold needs moisture, some darkness, some stagnant air, some warmth and a 'host' to grow.
