This seems counter-intuitive as I doubt you’ll ever find a really good PM company but the headaches of managing any kind of a problem remotely overshadows the ongoing concern that a PM company is inefficient and expensive (at least it does for us).

Kind of a different ballgame but also kind of just like it’s always been.  

To support this guess, in the very same (!)

- We had 2 break-in & furnace & HWH thefts there this year:(File a claim ASAP, you'll need:1) Utility bills to prove electric & gas were on2) A police report, proving a break-in3) Pics/video to prove the condition of the property to support theft claimWhat are you doing to mitigate additional damages?

You’re going to want some kind of “official” to declare she is of sound mind to sign such a paper.

If there is any kind of damage to the house because of a natural cause if you approach the insurance company without a landlord's insurance they will outright deny your claim.If you have a mortgage the bank will insist that you have landlord insuranceTenant has renter's insurance.

You might also want to look into supplemental insurance for future stays, like Proper Insurance or Safely, to cover situations where Airbnb’s support falls short.I'd be happy to help more.
