If by "market" you mean the stock market the answer is a resounding NO! You will most likely not net over 4.65% over the term of your loan. Even the best of the best can't guarantee this. If anyone does, run from them as fast as you can. If you do, great. If you don't, you're homeless and your credit is destroyed. Remember I said net. Investing is a game of risk vs. reward. The reward in your case does not and will not justify the risk.
Let's say you do this and for a year or two everything is going fine. Then in the third year you lose 40%. You will probably do what most people do and sell to guarantee your losses. The stock market is ruled by those with no emotion. It's hard enough to remove the emotion without something as emotional as your home tied to the money.
Now if you are talking about real estate then the answer is still no. You would be much better off selling your home and moving into a multi unit and letting tenants pay off a large portion if not all of your mortgage.
