It sounds like they have been paying, maybe talking to them about your concerns can help them better meet your expectations.

However, a lot of concerns can be mitigated with looking at their past rental behavior in a lot of different settings.

There is some financing available but it's rarely used, as it's extremely difficult to make a deal profitable given the lending conditions.

Because your statements are extremely misleading (unintentionally I suppose).

So cash flow isn’t the biggest concern.

I've consulted a few times over the years with planners and with the way I buy properties, my liquidity requirements, and my concerns about about how government overspending affects the future, makes me a poor candidate for IRAs and 401(k)s with the stifling regulations.   

This was extremely frustrating since he charges a pretty penny for closings.Based off my experience I would not recommend him for a 1031 transaction.

For example, if you have no experience in land development - that is extremely complex and risky compared to owning NNN rentals. 

You must have helpful Section 8 agencies - anytime I've talked to the tenant's caseworker about issues they just say "not my concern".

This is a touchy subject.If you observed specific concerning behaviors during interactions, such as rudeness, aggression, or disrespect for property, these could potentially be valid reasons for rejection if documented properly.You should add one very important things to do on your checklist, past landlord references and it must be legit and find out why they aren't there any longer.
