I've talked to hundreds of people (in my market) that want to wholesale.  99% of the time the reason they want to do it is because they want to use the profits to buy rentals or to buy flips. 

I don't know where the name "flipper" comes from, sounds negative to me, I am an investors that assigns real estate for a profit, have been doing this for over 40 years, have a large portfolio of properties, an auctioneer and developer of commercial properties.There isn't much I don't know about assignments (flipping) - what would you like to know?

Other investors and lenders like to see overall performance first (overall gross and net profit, operating expense, annual return in percentage etc).

Would investors still be interested in this and could there still be a profit margin or should I back out altogether?

So you’re building equity at $186/month, which you should include as profit.
