Any credentials or photos of past projects would be great as well.  

Congratulations on your project!

@Dillon McGough  Location,Security,exit strategy, Good Project management/Contractors is a must.

This LLC will give/loan(not sure what the correct word is) money to my cousin's Company, and there will be an agreement to get a percentage of equity in the construction project(i.e each of the 6 investors may get an apartment after the construction project completes).

Somebody thought it would be a good idea to do a major interstate toll road project and build a new stadium at the same time. 

Are there any creative but legal ways to use my personal funds and the SDIRA on the same projects?

It will be a project that involves some $$ investments.

They will typically ask for 15-20 % of the total project costs and at least 6 months of mortgage payments to fund your project.

Good Condition, under served market, and buying at $19 per square foot.....Projected to be worth double acquisition cost within 12-18 months....The point being that Cap rates are a good place to start but a terrible place to stop your analysis:)  Good luck in what I know to be a phenomenal niche!!!!

I don't want to carry a note forever (love the idea of the income, but I need the cash for other projects), but I'm willing to do it for a year or two.This seems like a puzzle to me - all the pieces are on the table, I just can't see how to fit them all together to complete the task.
