Out in small town Iowa our Selfstorage development has dried up due to the high cost of building versus low rental rates.  

If you start with a dehumidifier right away, you can prevent any growth on the backside of the sheetrock, and once the walls and area are thoroughly dry, the mold will not continue to grow.

And dog hair stuck to trim that hasn’t been cleaned in who knows how long.

Thanks for reaching out, I’ve been trying to find a multi family property out near Lancaster county pa, but it’s been pretty dry out here lately  

We recently just put a dehumidifier down there and are looking to dry lock the basement 

Even if you do preventative things it won't keep it dry.

It's been great in years past, however, due to saturation and stricter registration/compliance requirements, bookings have really dried up here and many are converting to longer-term rentals. 

I can about promise you Statefarm will leave you high and dry!

They said everything looks nice except the toilets are dirty and there is hair in the bathrooms.  

In my situation, a professional clean up crew repaired everything and also didn't find any mold inside of walls before starting the cleanup and new flooring and dry walls were installed and it was over ten years ago.
