The I had to buy a special hurricane door and window after hiring  a "special" welder to cut and re enforce the openings.

Maybe, they have liens and judgments against them that by you negotiating you can save a truckload of money.Ex:  code enforcement against the property that you can get reduced by bringing the property into compliance.  

Do you:Have a lease agreement that is enforceable and conforms to all federal, state, county, and city regulations.Know how to enforce a contract within the limitations of the regulations?

Contact code enforcement about the neglected property.

Nothing will happen overnight but I can't imagine hotel groups not going lobbying for better enforcement/regulation/etc. of vacation rentals as a way to keep their demand up and occupancy high.

Proper identification of tenants is also needed if you want any chance of having local code enforcement write tickets against the tenant and not the owner.Any Legal Action Documents: you’ll definitely want to know if the current landlord is evicting or suing the current tenant(s).

What you put in your lease is what you are expected to enforce. 

They don't have the budget to enforce half of the responsibilities they have been saddled with, and they must focus on the big dollar situations where there is some return on their investment of time and expenses.  

I've only ever enforced this with habitual problem tenants.  

My husband has been in law enforcement for nearly 20 years, as well, and we have friends and family who own in TN - meth labs are a real thing in East TN, we know.
