Quote from @Matt Godwin: Hi BP fam,Here's the situation, I currently use OpenPhone for all of my real estate business related communications (e.g., talking to buyers, sellers, other agents, etc.) as I want to keep my personal cell phone number private.

we do not communicate at all with our tenants as we use property managers. 

I discovered that communication of information and expertise counts.

Unless you have their contact info and are comfortable reaching out, Honestly handing them off to the local police station is probably your best bet.take pictures, and record any communications with the authorities to cover your butt.

I’ve seen both approaches, but I’ve found that keeping the OTA house rules simple works best to avoid overwhelming guests.

Open the door for communication, but never beg.

It's as simple as that. 

If you want to keep it simple, go with Stessa or a simple spreadsheet as a P & L.

They’ll handle most of the day-to-day stuff—guest communication, cleaning, and maintenance.

This means that businesses must obtain explicit written consent to add customers to a subscription list and send them marketing or promotional communications.
