Does anyone know of a course/program that can provide information on the best way to sell my excess motivated seller leads to other investors and agents?  Thanks for the help.

How much? Really motivated? If there truly deals... Then you don't need a course. You need to go to escrow. I get motivated seller calls too.." Why do you want to sell?" ."because I want to buy a bigger house". Never bought that house. 

The only thing I'm selling is deals not leads. 

yeah if its a good deal I would get any and all under contract and have a few  different exit strategies. 

If I had an overflow of leads I wouldn't "sell" them but I would hand them over to another interested party for a referral fee. I feel like selling them could be tricky cause what you may consider "motivated" the person you sell them to may not. Just find someone you trust and let them follow up and have them give you a portion of the profit.

I have over 9000 active investors connected to me on LinkedIn all over the US.  If they are really motivated, contact me and I will move them.  No course needed of course :)
