Borrowing money and then investing it — smart or nart?
The biggest concern is how you get $250,000 in unsecured credit. It's unlikely that you will be loaned that amount at a percentage lower than what you expect to earn. Unsecured credit lines are rarely lower than 10% and usually approach 20%. On top of that, for a bank to approve you for that credit line, you have to have a high credit score and an income to support the payments on that credit line. But lets suspend disbelief and assume that you can get the money you want on loan. You would then be expected to pay back that 10%, but investments don't go up uniformly. Some years they go up 15-20% and other years they go down 10%. What do you do if you have to sell some of your investments in a down year? That money is no longer invested, and you can't recover it with the following up year because you had to take too much out to cover the loan payments. You'll be out of money long before the loan is repaid because you can expect there will be bad years in the stock market that will eat away at your investment. There were a lot of people who took their money out of the market after the crash of 2008. If they had left their money in through 2009, they would have made all that money back, but if you have a loan to pay you have to pull money out in the bad years as well as the good years. Unless you have a lucky streak of all good years, you're doomed.
