Just my thoughts, I'm no investing expert. For example, essentially you have say $10k out on loan at 5% (-3% for inflation, so 2%), and you invest in stocks at an expected return of 10% (-3% inflation for 7%.) So you stand to make a lot of money right? Except take out your 2% you're paying in interest on that money invested so you're down to 5%. Now factor in that the stock market is plus or minus 18%, and you've increased your risk and lowered your reward. So pseudo-leveraged by my understanding. Not sure what else to call it.
I don't know for a fact how the math works out, but I'm pretty sure it's an increase in risk. You stand to lose more money than you started with, with a bad return, rather than up to the money you started with.
Ok - I might not agree with what you've said but at least I can understand it for now.
Yes, investing the money vs. paying off the loan early carries the risk that the market will go down and you will have less than what you started with. It was more the phrase "increase risk
exponentially" that I was questioning (empahsis added).
Also, if you pay off the loan early, you loose the inflation hedge. So you gain that by saving vs. paying down the debt.
Finally, while it is true that the markets can go down (typically only for 1-3 years), I disagree that you would "increase your risk and lowered your reward". It is actually more common for stocks to increase in value than it is for them to decrease in value. So you are actually increasing your (potential) reward, not decreasing it.
in sum: paying only the minimum on the debt allows you to reap the benefits of inflation, and reap any gains in the market.
Since the loan is at 4.75% and the OP has several years for normal repayment, history favors investing over debt-reduction.
