Mark Twain said it ain't what you don't know that will get you in trouble, it's what you know for sure that just ain't so.There are so many people out there making assumptions that are just plain falseThanks for your insightGino 

I will say that I had a difficult time getting a person on the phone in the beginning a few times to get issues fixed, but I haven't had that trouble in a while. :) It seems best to e-mail them and request a phone call if you want to speak to a person about something. 

A 6 ft fence will be installed between the 2 units

If you were having trouble with maintenance, tenants, evictions, crime, etc why would you think the property manager wouldnt as well?

I would say, if your on the fence about it just visit their Youtube channel, watch the reviews and the people they bring on to talk about they're experience working with them.

Also could you put up a fence

Trying to keep an existing tenant often produces more trouble than it's worth.To answer your original question, you should absolutely give them a deadline and a consequence.

Does this mean the guest is immediately calling to get it reinstated when they get the notification, or is someone in Airbnb support throwing this over the fence to another department that does not know what they're doing and reversing the decision?

I currently run a successful Airbnb and want to expand but am having trouble connecting with owners or real estate agents to help.

If state law says that you have to have an agreement in place before doing anything (the Minnesota example above), then you sign a "no agency" agreement and vet the person.Where you would get into trouble -- with your own principal -- is when you say that you are refusing to vet people who may be qualified.
