All these providers have in-house PM and have already done major capex so I think I've minimized my risk as best as I can, but again this is as much about the education as anything else so I'm trying to keep that in mind.Anyway, I look forward to this experiment with excitement and I'm cautiously optimistic it will go well.  

Two questions: Is there something else  I can do before I blast their name everywhere with an accurate review of what happened and how terrible they are and/or file in small claims?

Normally I'd refinance but I can't let go of that interest rate (especially these days) or else I'd destroy my cashflow. 

In a worst case scenario the due on sale clause could be called creating a mess for everybody involved and ending up in a lawsuit (no fun IME).  

My repose to both the tenant and Section 8 was that the $200 increase was still below maket rent and the tenants was free to move somewhere else where rents were cheaper. 

Online videos on social media platforms, educating your clients about nuances in private lending, coming on a popular blog to help people with financing issues, and connecting with others in your industry that specialize in something else.

My advise is to start with single family or a small multi-family ground up project first but this market environment is truthfully not the time to be completing any ground up projects unless you are self performing the construction which it doesn't appear you are in a position to do.There was a recent Philadelphia  forum chain started by someone else who was contemplating ground up in a similar fashion to what you are proposing and I cautioned they would be better off buying something that was newly built and believe after conducting their own diligence realized it was too cost prohibitive at this time to build with 3rd party GC's in Philadelphia when also accounting for the interest rate environment and cost to build.

Has anyone else received a distribution?

You're doing everything right, like someone else said, just give it time.
