I would vote for paying off the mortgage also.
The OP states that there is enough to pay off the house and quite a bit more. The real variable is how much more is quite a bit?
If there is enough to pay off the house and still have over $100,000 left, that is still very liquid with no mortgage to boot!
I also would look at it this way. If I leave my money invested, then I have to use "my" money to make the mortgage payments. No matter the choice you are going to be way ahead in the long run!
Good luck with your decision!
