I have been trying to discover a meaningful method to read the areas social structure, economics, etc. 

When it comes to the profit structure for a syndication consisting of a sponsor, general partner, and limited partners, typical splits are 30/70 SP/LP and then increasing the sponsor's split under a waterfall. 

Project 80% complete, migrating out of hard money into permanent debt structure, seeking non-recourse loan to fund the final leg of work and repay HML in one go.

With this structure, I will increase my cash flow in the beginning and have a total payoff time of 11 years and 10 months.

You can get a HELOC for half that rate.You wrote "...tap into my home's equity without taking on the burden of direct debt," but of course you still have debt, it's just under a different name/structure. 

Im looking for a great contractor who can work with structural additions.

I'm currently shifting some of my assets into small single family homes in a part of the country where real estate is still pretty cheap. Each house will have roughly 25k in equity. My concern is that it's a huge hass...

I believe in the project and the people, but I don't know how to structure the deal. 

But if you ask me what is the most important to have when acquiring multiple rental properties with multiple tenants, I would say that the number one priority is having a very strong insurance policy structure as your first line of defense for any unexpected/extraordinary events.

The DST has the advantage of being 1031 compliant as do the Tenant In Common (TIC structure), and for the most part any NNN stand alone or land lease.
