Slow the roll if you can ... paying 25% in taxes to pay off a mortgage of less than 10% interest rate may not be wise. Quit the job if you like and sell off enough each month (or couple of months) to pay your bills to allow the investments to remain for a while longer. As long as they are making more in earnings/value than the mortgage interest this would be a better choice. There is no need to "break into the piggy bank" any faster than needed. Splitting this into more than one tax year helps as well ... if you are not working next year than the taxes would be lower.
