The huge psychological advantage of paying off the house is that it's a hedge against panic during a major downturn. If the house is paid off you'll be less worried about the stocks taking a hit. You may think you won't panic sell but unfortunately were not all robots. If all your money is in the stock market you could panic sell low and also lose your house. If your house is paid off you could also rent out part of it receive some income to help you get through the depression/recession.
Or... you could not do that. You could follow the sage advice of the hitchhikers guide to the universe and decide you "dont panic". Maybe grab a towel as well, and throw back one of those pangalactic gargle blasters, heres a recipe.

"The Pan Galactic Gargle Blaster is an alcoholic beverage invented by ex-President of the Universe Zaphod Beeblebrox, considered by the Guide to be the "Best Drink in Existence"[1]. Its effects are similar to "having your brains smashed in by a slice of lemon wrapped round a large gold brick".
Beeblebrox advised that you should "never drink more than two Pan Galactic Gargle Blasters unless you are a thirty ton mega elephant with bronchial pneumonia".[1] However, Ford Prefect ignored this advice and consumed three Pan Galactic Gargle Blasters while at Milliways.[2]
Mixing InstructionsEdit
Take the juice from one bottle of Ol' Janx Spirit.
Pour into it one measure of water from the seas of Santraginus V — Oh, that Santraginean seawater! Oh, those Santraginean fish!
Allow three cubes of Arcturan Mega-gin to melt into the mixture (it must be properly iced or the benzene is lost).
Allow four litres of Fallian marsh gas to bubble through it, in memory of all those happy hikers who have died of pleasure in the Marshes of Fallia.
Over the back of a silver spoon float a measure of Qualactin Hypermint extract, redolent of all the heady odours of the dark Qualactin Zones, subtle, sweet and mystic.
Drop in the tooth of an Algolian Suntiger. Watch it dissolve, spreading the fires of the Algolian Suns deep into the heart of the drink.
Sprinkle Zamphuor.
Add an olive.
Drink... but... very carefully..."
You should be good after that. You have avoided nonsensical anti-mustachian monkey choices. Enjoy your vast quantity of monies ;P.
Sweet I've helped ^^.
Edit: Sry, bored :|.
Edit2: I'm just teasing, I fall into the dont pay off camp, but yeah w/e =]. I personally think you should just do the best in your situation, if your not its just a disservice to you. If it's really best for you despite the downsides thats cool, just throw out the illogical and wimpy self as much as possible when choosing.
