I provided email communications between the client & myself, screenshots of the prior 3 years hosting, screenshots of the Domain Registration in the clients name, & the website being online.  15 days later, they pulled the funds, 30 days later, they closed the investigation. 

It prevents emotional knee jerk reactions to market volatility and world geo political events.

Like others have mentioned, if you kept communication in the Airbnb app, they can see everything and don't allow blackmail.

Clear and constant communication regarding progress and deadlines is important with contractors, they're often overwhelmed dealing with a ton of moving parts and trying to juggle more than one customers expectations. 

If you pair it with a good lender who can communicate the full menu of financing products and strategies, and make good recommendations, you will be in business.

We take their lunch money every year because clients ultimately don't care about the brand - it's the systems, training, communication, and people that can keep clients happy (or not.) 

I would more so worry about fixing the actual issue than dealing with the emotional aspect of it. 

We normally try every form of communicating including door knocking and door postings

I always think communication and cooperation are MUCH MUCH better than going to court to try to enforce anything.

They were very unhappy they had spent the money with TurboTenant and it is apparently not communicated that not all property managers/landlords will accept TurboTenant applications (which is true for the ones they haven't noticed are not using the TurboTenant applications apparently, which was us, until today).
