It is a large plate glass window with a 1/2 round above. 

You must call Airbnb before you do that, and send proof of repair issues serious enough to require cancellation (photos and repair time estimates) BEFORE you cancel on the guest. 

A common pitch for realtors looking for listings is to declaure they have a large database of “buyers” they will bring those buyers by to see the property, but often zero proof of its existence..

I am thinking  it was recorded by the seller or the wholesaler that was trying to sell this property prior to going up for auction but have no proof who it was. 

I'm currently working through my credit card company since they provided email proof admitting their data is old, at least in the two states I am working in. 

So, I have proof that I asked two ways three different times to show a judge, if needed.I did have a tenant call and ask for the check and accounting once about two months after he left and I explained the process again. 

The description kept mentioning a fool proof system, and then the pricing for it was exorbitant.

First you need proof of concept that you can do it on your own.

Anyone else hear of passed legislation mandating the property managers in addition to property owners are now responsible financially for any repairs not done on properties, taxes not paid and rental certs not submitted/paid for, lead based paint fees/apps and required work, HVAC certs every year and proof utilities (water/sewer) as paid, and general compliance matters?   

Personally, I'm a fan of going studs out because I can QC the process and make sure that things are bulletproof for the foreseeable future.
