RE agent/LLC FLIP PARTNER commission contribution

[Izzy Marker]

We formed an LLC to flip houses - Partnership is 50/50. Partner #1 funds 100% guarantees loans and handles all the bookkeeping. Partner #2 married couple: W is the buying selling RE agent on every house in LLC and Husband oversees contractor/project.   We talk daily and make big decisions together...   

Note: LLC has bought/sold $12 million over the last year with and made a profit of 650,000 (without any of the partners RE commission contributed to the profits)

Going forward Partner #1 wants the RE commission to be included in the profits - less a flat fee to her.   We would really appreciate some ideas on how to structure!!
