I'm interested in better understanding the structure of JV partnerships.

I will say this..most agents have no clue how to structure it properly. 

And for other reasons, it's important to know what the debt service is so you know how to structure a deal. 

Now, on that side (loan from bank), I have no idea on what that means, or how they are structured, what is allowed or what is not.

The main reason is liability protection, but as @Terry Alexander mentioned, when you structure your entities correctly and do so working with lenders, it does open you up to a much larger pool and world of financing.

If it's more than that, we figure out how to put some structure so everyone gets to meet folks they'll be excited to meet.Personal opinion: it probably doesn't make sense to ultimately aim for a separate organization outside the existing REI groups, but we all have BiggerPockets in common and it'd be nice to meet others on here.  

Once you have a clear understanding of your deal, then we could discuss your fee structure.

In the past I  worked for two NFL teams and in physical therapy clinics.Is your passive or business income from real estate the same, greater, or lesser than when you were working a job?

Or structure it where the fee comes out of the sellers side.

Do you want to be able to physically drive past your property or will you be content to trust someone else to do it?
