Airbnb doesn't make this obvious and most hosts miss it (thinking they've done what they need to do by listing it in the description), and if a guest complains about the doorbell and it's not listed there Airbnb bans your entire hosting account (and all of your listings) permanently, with no recourse.These are a very small percentage of hosts in the grand scheme of things, but for people with a lot of listings making the majority of money on Airbnb it's a lot of exposure/risk to have that all in one place with a company that has a history of just kicking people off the platform without any explanation. 

@Ryan Schumacher As a property claims adjuster I highly suggest getting as many photos and documentation of the damaged areas as possible before the contractor does any kind of permanent repairs.

If you have 10 million to invest you can live pretty fat on just talking a partial amount of 700 to 800k each year so it's all relative.

Trial and error...and even then it may not be a permanent solution. 

But I am against them in residential neighborhoods where owners make their permanent home and raise their families.

if you are a cash buyer, they have a nice fat 10% down payment, they are sitting on !!  

Your health hasn't been "permanently damaged" by this.

Either provide them or reduce rent if they build permanent structures.
