If it hasn't ever been painted/coated since original application just doing that will help hold it together and prevent dust;  that work should not be too intrusive.

I know a lot of other agents agree with me that it's an unnecessary risk to the seller.The other differences I find interesting are that Mass is an attorney closing state where Maine uses title companies. 

It could be to improve the installation now to prevent future repairs, add additional money into your ongoing or future expenses (for potential repairs), or do nothing.

See if they are open to providing additional security deposit funds as a gesture of good faith, since the property is clearly getting more use.As a take away, you now know never to rent to pilots again, and/or change your lease in a way to prevent a crash pad (perhaps use that very term in your lease and define it).

And at 8 pm last night finally responded to state a family emergency out of town will prevent her from taking the unit. 

I want to switch them all to LLCs, but my current loan documents prevent that. 

There is no sure fire way to 100% prevent it, however, this is what I do: Each investor I add to my list, I inform them upfront that if they commit to funding the deal and then back out, I will never do business with them again and may tell others in my inner circle about my experience with them.

I mean ceiling falling seems like mandatory maintenance, I would reschedule and tell her if she can’t let them in next time you will be there. it's not literally falling, but cracking a little, and it can happen anytime, so we always like to be prevented. .we're trying to fix it for months..the problem is she won't let is in only when she's available.  

I don't see how they can prevent a double closing though, which is entirely a method of wholesaling.
