To confirm my recommendation ask him for references at his current developments, I bet he won’t give you names and will make up an excuse!

Then, when something looks odd, you can reference the deep-dive report to better ID it:)

Best bet is likely (not absolute - everyone's situation is different) is to look at a national lender or broker that has options in lots of states - its a great development versus 20 odd years ago, with technology, internet, places like this - can have access to many more options than before (local broker or lender thats it)

The departing tenant says she will continue paying rent, but I wouldn't bet on it.

I too at first thought it odd, that they didn't have a big internet presence, though they've been around over 6 years.

The owner needs to know you are solid, a good bet.

I bet people will not be getting paid their dividends very soon.

I obviously have no way of verifying whether you own the asset or not, but find it odd that you'd throw away years of attempts at building your reputation and leave BiggerPockets rather than simply shut Melanie up by stating that you own the thing. 

The debt may not report to your personal credit (unless you are late on or miss payments, then all bets are off)2.

Sounds like their combined income likely beats your other tenants.Your gut is probably your best bet and you need to go with it.
