It has me worried the training will be the same, leaving me out to dry during test time.

They are all metrics that help define cash flow so I'm surprised you're asking... frankly they are all different ways to skin the same cat.You can't just look at cash flow...

If your investors know that you have skin in the game you'll mitigate some of their concerns.It's important to remember that people don't invest in deals, they invest in people. 

If that doesn't toughen one's skin, nothing will!

I have friends that did tons with REO and now that has dried up and they had to let a lot of people go.I equate it to a high volume restaurant where they are doing 2 million in sales a year but profiting 200,000.

It seems that those that had major issues were doing low to zero down and hoping and praying for appreciation...oops.I've mentioned before that my plan is to start acquiring rentals, targeting B range properties doing conventional financing (20-25% down) until that option runs dry then figure it out from there.
