Thankfully never any injuries at any of my properties, that’s what scares me.

If someone gets hurt on your property and they are not insured you will be liable for there injuries.  

So, you pay someone to push you to work out for short period of time, with specific exercises to "fix" a specific injury.

Liability (covers your personal Liability for Bodily Injury and/or Property Damage)7.

A homeowner insurance policy usually has $300,000 in liability coverage (property damage or personal injury).

"Additional Insured" protects the Property Manager if there's an injury or someone sues.

Payroll tax, insurance, workmen's comp, injuries, laws governing your actions, mileage etc...If you don't want to pay a full time or part time employee and take on all of the headache's that come with employees, why not consider outsourcing all maintenance to one local contractor.  

Lots of them are on SSI for different injuries, which is where the rent check comes from.

I prioritize repairs by some basic criteria, starting with issues that need immediate resolution because they either cause continuing damage (leaks) or could result in injury (mold, holes in the floor) or just make working on the property easier (plumbing and electrical systems).  

Most likely the state where the property is located is where lawsuits would be brought if they are something for personal injury like a trip and fall or something of that nature because the “cause of action” arose in that state.
