So far, they have held up just fine, so I will definitely stick with them because they are so much less messy and because re-seating a toilet is no problem whilst you only really get ONE shot with a wax ring.That said, of course, it will be a very long time until I can truly comment on their durability vs. a wax ring since those often last many decades.  

These are separate units that are either reported on SchE or SchC depending on how they handle them. 

From my understanding so far, an LLC is helpful in that it offers tax advantages and asset protection (if handled properly).

How do out of state investors usually handle this who don't have a PM?

Like iwill do all the handling from cleaning,  answering to guests, bookings etc and I'll just pay my partner a percentage for letting me leverage her hosting power To run my airbnb business?

Bad situation, but silver lining is you now get to see how the PM handles the situation.

There is some time involved also in waiting for the background check and it is largely a process you have to weed through on your own as there isn't much written on it.I would recommend talking to someone like @Daniel Anshus to see if you can work some sort of deal for handling both transactions. 

I hope so but not sure how Vrbo and Airbnb handle this. 

It is priced right so you can handle the vacancies, and once fully rented the NOI will be even better.

I would be handling everything involved with closing the deal, hiring management, and increasing NOI.
