No again, I'm sure of it.Does any real estate school give your money back  if you can't pass the test, no, but they may give more instruction, have you keep taking the test and they might beat a dead horse if they have to, but I don't know of one that gives you all of your money back. 

ok, flogging a dead horse but here goes. 

NOI is your nominal yield amount, the cap rate essentially provides you a yield % on your investment which provides clarity for comparison to other real estate options or dividend paying stocks or interest bearing bonds or any other investment which provides some form of cash return outside of simply appreciation.

I would look at a 6%, you have a 60 year old multi unit on Susquehanna next to public housing, yeah, I want 12%.Cash on cash is a better metric just on the fact that you can also compare this to how the stock market is doing and other investment (non-real estate) will do. 

The operating agreement should address possible arrangements, how you admit another member, events of withdrawal, voting rights (might think in terms of a corporation with preferred and common stock as to voting rights), buy-sell arrangements and authorizations granted to members or managers.A good attorney isn't just a lawyer they are also planners that can map out the direction of operations, they can be the gatekeeper that allows flexibility but keeping you on the main track. 

I got tired of watching my stocks grow slowly and decided I trust myself with my money more than I trust the stock market.

I went to a similar stock options trading seminar once where they showed you all the ways you could make $20k in a day by trading options.

If the stock market had performed the way it did in 2014 with an 11% return, it would have been really crappy for the investor that funded the project.So I got lucky you say?

Definitely don't sell them to invest in the stock market!
