I have been looking into recruiting real estate agents to work at NEXA LENDING and/or AXEN REALTY as a BDM

Can anyone explain what’s the BDM position entails and the difference between BDM AND DUALLY LICENSED MLO AND REALTOR. DO BDM POSITION NEEDS TO BE LICENSED as an MLO or REAL ESTATE AGENT? Explain the difference between the two positions and how you get compensated and how the fownline system works as well as the revenue share system. Thank you
