I would be very careful about interpreting data, especially with real estate. 

This is NOT, I repeat NOT typical of an Airbnb rental.

Personally, I prefer to manage all my properties because a) no one cares about them more than me, b) there's no PMs in my town worth a crap anyway, c) my properties are fully renovated and rent so fast that PMs would do virtually no work for their pay anyway, d) I'm a control freak, e) I make more money. 

They are getting to the point where they need around the clock care and need to sell their house  where they lived to help pay for the health care and living expenses .  

I am part owner of an LLC which holds our two rental dwellings.

So far I have been unlucky with the few prior brokers I worked with.Either they have no clue how to deal with rentals and LLC or they never follow up on requests and I have to chase them down for weeks before getting any  return call.I am looking for a broker who could take care of all my insurance needs for my home, LLCs with rentals, condos, commercial and personal liability, etc...

It does seem like a risk I wouldn't want to take.I'm sure you will, but be careful to use insured and licensed remediators for lead and asbestos, if for no other reason than liability. 

Lenders want to know if both have stone countertops, jets bath, hardwood flooring but does not care it is engineering or gleam wood flooring …..

I won't touch your comment about the investment being 100% driven by appreciation, there has been plenty written about that in the past.If you don't care about the expense of a property manager than sure, hire one.

Take care,Nick
