the per door rate is an incredibly oversimplified view of the financials a project will produce.What's the expense ratio?

Looks like a fun project.

If the company complete the process of review in a positive way and is being announced that the landowner doesn't have enough money to pay for construction, then they look for lenders who can agree with the profitability of the project.

They never made an interest payment nor are the projects completed and sold and I funded these in August 2018.

So if you TOTAL project cost, land + construction, is 10mm if only using the land it would need to be worth at least 3.5mm.

I would rather I be there for any given project and not the tenant.

Lastly, any new home builders and/or modular home builders in NJ who would be interested in a project like this?    

Project management, SCRUM, additional users would be amazing but a secondary requirement. 

I would certainly rely on a real estate agent to pull true comparable rentals in the area (as opposed to any kind of "Zestimate") to know what your projected rents might be.

Roommate situations can be tough enough for a landlord as it is so adding a bad tenant on top of that is not a good idea.
