When I haven’t even closed a deal yet and she kicked me out of all aspects of the course 6 weeks ago because I started asking for proof of her $925,000 she claims she made last year in the group meetings.

Expecting brokers to inform you of the best purchase opportunities when you have no proof of funds, or pre qualification for funding 9.

I only know about the times where this was found out prior to closing, obviously I have no way to know about the times this shady behavior wasn't found out.Since you get a vote in who this tenant is, and it's retail, PSA that commercial lenders (especially the ones offering the best terms...) are starting to vet deals by how 'recession proof' the tenants are, even if they are currently paying on time.

Not sure about NJ, but in Florida, you have to have proof that the tenant caused the damage. you are claiming on the deposit.

I have not proof read this, so I may have skipped stuff in the explanations. 

I would do the following, at a minimum:-request that he complete your rental application (hopefully you have a thorough application),-request identification documents (government-issued),-require that he provide you with proof of his visa status and the authorized length of stay,-verify his employment, income, and financial stability, and-contact his previous landlords for references.If he cannot satisfy these application requirements, do not approve.

I try to make the properties tenant proof and that they feel safe.

I am paying for that now.I will also do all of the other due diligence prior to investing - experience of the operator, referrals from those in my Community and network who have invested with the operator, responsiveness and other factors - but proof of effective communication will remain a priority for me. 

I'd be sending copies of the video to the car rental company and insurance company, so they also have proof it was the guests' fault. 

Obtain proof of verifiable income, which you then verified?
