There is some short term volatility, and a short term inflation runup, but it will correct itself. Always does. Can't be afraid of current market conditions. If you are, you won't benefit from the longer term run up. If you're looking at a 36 month time frame, your investment will do better than the lower interest rate of a loan. No doubt. I'll be happy to pay 3% when the "cash" amount is gaining 7%+ net of inflation in investments. I do like no payments/being debt free, but as long as I can withdraw the funds and zero the loan at will, I'd rather my money work for me.
