I am but the "money man" - earning a fixed return plus bonus points; my flipper (who is also a broker associate) gets to keep the majority spoils, but also assumes the risk of mis-estimating repair costs, time-to-fix, days on market, and everything which cuts into his eventual profits (without affecting mine).  

Bonus points if you have done this in any of the following metro areas:Philadelphia, Pittsburgh, Louisville, Chicago, Richmond, Hartford/Central Connecticut

Another good way is to market to those realtors who bring you buyers is with an agent bonus.  

I originally had the house at 2.5%, however increased it to 3% as well as an extra 1000$ bonus.  

I work with a builder if you're interested in buying some lots and building and selling prior to the home is completed for a nice profit.https://ajames.leadpages.net/what-is-your-home-work-early-bonus/

My passive income is much less than my salary and bonus was, when I compare them before taxes.   

Employee bonuses are based on the accuracy of their home bids and rental estimates.After submitting a bid, Starwood Waypoint employees visit the home with iPads and take it through a 45-minute inspection, marking what renovations need to be made.

I have not been responsible for the selling of our currrent properties, but Intend to change that and see what kind of effect offering something like a closing bonus of $10,000 gift card would have on selling properties at higher margin or (at least as negotiating tool).  

As a bonus, the municipality allows two family dwellings on lots zoned single family residential, so potentially four units could be put on this lot (if it is subdivided).

There are many methods of figuring the split......priority return before profit split, percentage, bonus, etc.
