And to be honest, there could be more but we are trying to be gentle with our tenants and not expose them to too much change too quickly (although some of it is unavoidable).  

There's always going to moisture, termite, and wood rot issues. 

Moisture is getting in and causing it to flake off DOORS (Interior): Adjusted a) the entry door to the 2nd floor left end bedroomb) the entry door to the master bedroom(2) The left bi-fold door for the laundry room needs to be adjusted to prevent it from dragging on the floor, whichcould result in damage to the door and flooring.

And I put a dehumidifier in the garage to help get rid of any moisture. 

For example should I make the place look pretty or spend a chunk of money preventing moisture in the crawlspace?

In general, way beyond normal moisture (dankness - I don't mean marijuana either) smell would worry me.  

We have to install on all our permitted renovations, and have had zero issues with bathroom moisture since using them.Not sure how that'd work in a whole house situation, but something to consider if you decide to seek a technological solution.Good luck!

It may also be why she rented from you vs someone who does credit checks.At this point, I think your best strategy is continued gentle pressing.   

I have a property under contract to close approximately jan 30. The pipes were stolen prior to contract resulting in water gushing inside and wet carpets etc. The humidity is high and carpets are not going to dry out....

It just means we need to deal with the relatively rare occurrence of someone requesting a booking and telling us they have a service animal or support animal and gently pointing us toward the ADA rules.
