Ah ha, and then you throw in there the actual changing value of the dollar and you really don't know what to do. The value of the dollar is constantly changing and changes more than one might think in 5 years. So then, over the course of 5 years, is your dollar itself going to be worth more or less, aside from investing it. Inflation, deflation, in what direction are we heading? Either way, those monthly payments may feel heavier in your pocket, or not existant....
And can getting 0% financing when you DO have the cash available really be considered debt? I am in debt on my house, I just do not have that much cash to pay it off, considering we just got it less than 2 years ago. However, I do not feel I am in debt on my tractor since we did have the option to pay cash, but opt for the financing with a large enough down payment to get the monthly payments where we would hardly feel them, without taking all of our savings. However, the fact that we could pay off the loan at any time doesn't really make it feel like a debt in the sense that we owe on something for which we do not have money (I would guess though that my feelings come back to the reason I have never owned a credit card.....Aside from the house, if I don't have the money to buy it, I am not buying it.)
