When it goes this far we usually order an air quality test.

They pull any moisture they can get out of the air, so if there are any small cracks or openings to outside air they will just continue running, filling up their tank from the moisture in the outside air and not working efficiently at drying out the space you’re trying to dry very well.

I’m active duty Air Force with four properties.

I am eyeballing my first Air B & B in Fox Lake, or neighboring town, on the Chain O'Lakes.

Will you rent through Air BnB?

I’m still up in the air on this.  

There will be some holes in the wall where they open it up to let air in and dry it out.

It's the visual thing for some people mostly, with such small wall space having it right there in your face isn't ideal. when at all possible, every flip will just get duct work and standard air conditioning. 

Are you going to pay your rent, or skip rent and book an Air B&B? 

But all well maintained with central heat and air.  5 of the 7 were vacant.
