Interest was always 6 percent, which was sometimes more than I was earning in investments, especially during the early 2000s, during the downturn and later when we had another downturn (2008?). The way I looked at it, not only was I making 6 percent interest, but I wasn't paying 8 or 9 percent or however much banks charge on a loan nowadays. So If you figure the average S&P 500 annual return is 10-11 percent, I was actually doing better than that. Now, I wouldn't recommend borrowing your way to wealth, but I suppose Dave Ramsey and Donald Trump would disagree with that as well.
