I believe you're going to want to find someone licensed in the jurisdiction in which the properties are located, since a general review from a landlord-tenant law point of view is state specific, and a prudent review for short-term rental use may include a check of whether there are any local ordinances or zoning requirements to which the property is subject.Not knowing the situation or any laws directly on point, in seeing that you'll have hot tub/pool, I would also want to involve and insurer, both to insure the property against misuse by short-term tenants (they wouldn't!)

They are paying for it, and they can use it as much as they like.I don't consider 24/7 use or 68 degrees to be misuse, because no where in any manufacturer documentation have I ever read that it was. 

You are right I may have misused the word “passive” - I could have been more clear on that.

This is probably a $60 job at most.The other question is can you prove the tenant broke it due to misuse?

Normal wear and tear or misuse?

Accidental damage(s) due to neglect, misuse or abuse of the property is not.

Generally, the LL/PM will have the repair made and make a determination whether or not the tenant is responsible for the cost due to misuse/abuse.

The windows will eventually need to be replaced in the future.I don't anticipate major capital expenses or repairs in next year or two unless tenant misuses things (e.g. paper towels down the toilet) or breaks things. 

In general, I will italicize or quote the word "wholesaler" in my posts because the word is misused and largely deceptive to the public when used in a real estate context.

Worst case scenario:  She is misusing the FCRA to hide her record of bad credit.
