How to cash out of owner financing

Is there a way for me to sell notes quickly on homes I have paid cash for, rehabbed and then owner financed? I have not tried this yet but need a way to move properties quicker than dealing with traditional financing options. I need more speed, any thoughts?

Sure, you can sell the notes easily. Many note buyers out there. The question is will you like their prices. They will price in a minimum ROI of 15%. Depending on the terms you wrote the loan at, that could turn into a very large discount from the face value.
There are note buying forums at places like Bigger Pockets where you will get a price fast.
