Question - Keep thinking about cashing out the stocks and using the money to pay off the mortgage.
That could turn into a "wish I woulda" pretty fast. I wouldn't think about it much longer, but do it. Good for you.
Like most things in life its a little more complex. As I understand it, the home/mortgage are what
the lawyers call
Tenancy in Common. Meaning the wife and I need to agree on this.
Of course it's always a good idea to have your better half on board with any such decision, but I do believe the only thing you would legally need your wife's signature for would be to sell the house, not to pay it off. Still, I fully understand and concur with your point.
