IMHO, doing this MIGHT make you feel better, but it's among the dumbest financial moves possible.
As a mortgage ages, your payments become far more principle and far less interest--that you paid early on, and it's how banks get rich.
Why would you do this when the odds of Tesla making triple-digit APR returns is almost a sure thing, especially given how so many in the finance media still don't "get" TSLA?
Recommend you not spend a dime to pay off your mortgage: sell NO shares, HODL!
Have no fear, been holding TSLA since 2011 & my mortgage remains intact.
