Bankers and financial advisers like to sell you on "over the last 100 years the market has averaged x%" so you should invest. They don't tell you about market crashes that wipe out 50% of your principal. Why would they? Over a 30 year loan, you're paying almost as much in interest as in principal at around 4%. Also, financial advisers get paid by holding your $ - which is what's important to them. The government wants you to invest in IRA and crap and then force you to take out a certain amount each year - they tell you the accounts are tax advantaged which isn't necessarily true. All these games are rigged.
The safest, smartest route is to pay off the mortgage. I have an excel file I can email that models out paying off early.
That's a fairly negative opinion of the stock market.
I'm not necessarily defending bankers and financial advisors, but when they state that over teh last 100 years it has averaged X they certainly didn't eliminate the crashes from teh equation.
The recent market crash in '08-'09 did wipe out a lot of "paper" principal for people, but provided that you didn't cash out at the bottom like a moron, then you've made your money back and then some... it's all paper gains and losses until you realize it.
Paying off your mortgage is the safe play, but some people have some truly microscopic loan rates these days whereby making investments is a very reasonable alternative to paying down your mortgage provided you have the proper time frame for the money and the proper risk tolerance.
If you're automatically investing, or manually investing but holding to a schedule where you're dollar cost averaging your contributions and share purchases, a market crash is a
great thing
if you're time horizon is long-term. Dentist is right, it's literally a paper loss, and when the market drops, you're getting more shares for your invested capital for the long term. Market gains just look cool on paper. If you're long term right now, you're actually buying more expensive shares of index ETF's and what have you that you invest in. But you're getting your money into the market and giving it time to grow up and down, while adding more all along the timeline.
If you have a big enough spread in your interest rate on your mortgage vs. your anticipated or historical stock market returns, it is kind of overly conservative and short sighted to not be in the market. Great, once the house is paid off, you have a lot shorter window to jam money into the market and let it grow, and lose your ability to grow in equities. Have fun working into your late 60's+ with your paid off house. Invest in sound, lowest fee possible indexes, match your risk vs. your timeline, and let the time value of money do its thing.
