Mold nightmare and house to safguard

[Ketan Parekh]

Hello! Team 

I have a few condos and do have insurance the units are managed by a Property Management Company.  While last month one of our unit was identified having mold - well after that it has been expense over expense. I was aware that insurance would mostly not cover but how does a landlord safe guard here ?. If the unit was given in good shape and the tenant does not aerate the house , keeps lot of humidity in the house there is bound to be mold growth. While the issue on hand was resolved we did stack up a good over 9K in expenses. 

What ever I have been reading on this it seems Landlord is always responsible :( which is sad as landlord is not living in the house and has no control how a tenant keeps the house. 

Any advise / feedback suggestions would be helpful in the future to safe guard here. 

Thanks in advance.
