I believe you should charge yourself 10%, if it's norm in your area because you will have to work and spend time to perform it and time is money. 

More specifically, I:1) Got the deal more directly than my partner for ~$5-15K less2) Negotiated and performed all inspections ahead of other prospective buyers3) Talked another investor out of the deal at the closing table to get the contract for no more than we originally planned (after over an hour.. one of the stranger circumstances I've experienced in a while, but got a smile, business card, and potential future partner in the process!

You will be taking over someone else's mortgage and your performance on that is tied to that individual seller's credit.  

I may sell the original rental for a better performing home while I still have the capital gains exemption.  

We are beginning to look at non performing notes across the country.

What about just performing an inspection to see what kind of condition you are looking at??

Here is the other thing ... from what I can tell, banks actually make more as the servicer of a non-performing mortgage ... so they have zero incentive to do anything.  

So, my plan is to start my management company and to hire agents/brokers to perform the deals since I legally cannot.I can handle the start-up costs but as far as paying the agent/broker, that's not feasible.

But after all that is said, thank for caring at least enough about the seller to pull out early when you realized you were not able to perform.  

I don't know if this applies in your area, but in California a licensed real estate agent had to perform a short sale.
