The due on sale clause generates a lot of debate on biggerpockets, but me and my colleagues have yet to see a performing note (a mortgage that is getting paid) get foreclosed on based upon that clause.

Seeking out a sale of the mortgage from the current holder of the mortgage (which may or may not be the original lender) is no easy task.  

I own a performing duplex and have successfully flipped one single-family residence.

Whether or not they fulfill that task is up to them, but it would likely weed out the majority of flakey tenants, no?

As the time approaches for closing I often think of a task, or detail I need to complete, and think "Oh yeah.
