What happens when the moisture in the room causes mold? 

It is important the documents are in compliance with landlord-tenant law for the jurisdiction governing your rental properties.In addition to the Lead-based paint disclosure form, for every property you will also need a disclosure about Mold & Moisture.  

If you do see some signs of "M" or mildew it is at a minimum a sign of trapped moisture.  

The biggest being that they usually destroy the window and the moisture causes mold.

It has great information on Mold Basics, Mold Cleanup, Moisture and Mold Prevention, etc.  

These people have absolutely no financial literacy and will obviously never be able to live in anything other than D-class rental housing because they will fail every criminal check ever done on them for the thing they did before finding sobriety.The large, gentle, utterly lonely borderline mentally-retarded man convicted at 18 of inappropriately touching a teenage girl, sent away to prison for a decade.

.• Metro areas which do not experience hard freezes or significant moisture.

My advice would be to raise the rent gently. 

Mold likes moisture.

Then we add an addendum for other things.... such as 8 pages property rules, 2 pages property condition report (move-in inspection list), 1 page mold/moisture information & disclosure, 1 page lead based paint information & disclosure, 1 page no-smoking policy, 1 page pet agreement, 1 page service animal agreement, 1 page "other", etc.I schedule 2 hours with new tenants for the move-in.
