Mentoring with partnership (fair split)

[Cesar Schira]

I am on my second mentor, first one was a guru scheme, didn't work and lost a lot of money up front. Now I found someone that seems to be the right person for me. Even though he is 800 miles away in another state he calls me and pushes me to get things done and shares his knowledge. Now my question is, he only asked that for every deal I do I cut him a 70% of my profits, 30% of something is better than 100% of nothing, but here is where I am troubled. I did all the work to get a house under contract that hopefully sells for $35k, after paying closing cost, realtors and seller I'll be left with approx $3000 and he will get $9000. I did everything, estimated the repairs, researched the property, negotiated with the seller and market it. Is it fair that I will only get enough to cover for my time, gas and marketing? And he gets enough for a down payment on a small house? Is there a better way to a fair split? Feeling that if I'm doing all the work I should get the 70%. It harder to find and negotiate deals with enough marging when someone else is involved asking that much in return.
