It looks like you are doing an affordable build based on the cost but hard to say since you didnt provide info on the build itself such as square footage and finishes.

@Timothy Frazier  This will be tough as the HML will want a 1st position loan, but so will the other lender providing the rest of the funds. 

Also, providing value to others at a high level will pay off for you in the end if you stick with it.

They should be able to provide a market rent range.  

Each grouping had a common room (perhaps it was shared by multiple groupings ... this was a detail I missed) with a nurses/aid workers office.Central to the two sides of the complex were common facilities such as a dining hall, gym {perhaps a pool ... another detail I missed}, theatre &  games room.With one of the fastest growing groups in our society being single people, we are examining a related idea of a  complex / building providing a modest-sized 1-bdroom "apartment" with more semi-private and common amenities.When I read the title to your thread, I thought it was a project proposing to mix students and seniors into a single complex ... and came in thinking, this ought to be interesting :-) 

By 2030, we want to have grown a portfolio of over 100 units, created a property management company that manages an additional 100-200 units, and, finally (and most importantly), we will have established a non-profit that is focused on quality, affordable housing that specializes in providing housing and resources at/on the "services cliff" alongside financial counseling and first-time home buyer education in our target area.Our target area is the Springfield, MA and Hartford, CT areas with dreams to expand to Central Massachusetts (Worcester, MA), Southern New Hampshire (Nashua, NH), and Southern Connecticut (New Haven, CT).Would love to meet up with likeminded individuals in our area!

I tried to provide constructive feedback on why it was not worth continuing with RentRedi and all the sudden I couldn't type anymore (it was about 3-4 sentences I got cut off). 

Do not simply trust a turn key provider, a wholesaler or even a real estate agent that is supposed to be looking for your best interest.

They are very nice and can be helpful providing you what you can and cannot build on your property (Set back, height restrictions, front look etc).

Tribes might even provide additional incentives, like grants or infrastructure funding, to encourage investment.
