The part about increasing the value of my house as its FMV goes up sounds a bit too much like counting your chickens before they're hatched, I probably won't bother with that part of it.
That's the nerd in me coming out, it's definitely optional and is a pretty much worthless entry if you don't have your entire financial picture plugged in. . .and even if you do, it may not matter to you. From my perspective, since I update my mutual fund values (for better or worse) it follows that updating any fluctuating asset or liability keeps everything consistent. . .
