Both EPA and the CDC have excellent sites
CDC Appendix C
Spores are almost always present in outdoor and indoor air, and almost all commonly used construction materials and furnishings can provide nutrients to support mold growth. Dirt on surfaces provides additional nutrients, cloths, etc.

IN THE HOME, THE KEY IS TO IDENTIFY THE SOURCE AND CONTROL THE MOISTURE/HUMIDITY.
*At present of the 200 common molds, there is no test that proves an association between stachybotrys chartarum (stachybotrys atra) or other mildew/molds, and particular health symptoms.
Individuals with sensitivities or persistent symptoms should see their physician; remove the cause or themselves from it.
As the home is on a MTM just 30 days is required notice.
Mildew or mold:
Blooming mildew or mold does not magically appear, when moist, the spores grow over time and for a reason.
*Mildew & mold spores are, naturally occurring, and are present in one form or another in the air and as such cannot be eliminated. CDC.
EPA:
Is testing or sampling for mold needed?
In most cases, sampling is unnecessary since, NO EPA or other Federal standards have been set for mildew or mold exposure.
Nor are there any over the counter (OTC0 or retail tests that are reliable to any degree more than 6%.
A certified lab may have a test for the type of mildew or mold.
Checking or sampling: EPA WEB SITE
Spores, sampling cannot be used to check a building's compliance NO EPA or other Federal limits have been set for mildew or mold
Sampling for mold should be conducted by professionals who have specific experience in designing mold sampling protocols, sampling methods, and interpreting results, not a company the remediates mildew and mold, as they have a 'vested interest' in finding them.
Rather an independent lab that is certified for such testing.
