I wasn't talking about fixed rates of return investments. It's hard to make money that way, especially if you need money from a vehicle loan to invest. Take away your fixed rate of return and your whole post falls apart. Keep it and it's a waste of my time to make pennies if anything at all since I'll take the cash back instead of low APR.
When I bought TSLA I knew I could lose all or substantially all of my money much like most of my investments. So I invest what I can afford to lose. If you need money from a depreciating investment loan then you can't afford to lose it. There's a huge difference to me between investing money I have to invest and money borrowed to invest which I would never do. I'm surprised you see no difference.
But thanks for the lecture even though it's was better saved for old ladies or men when selling reverse mortgages. They make the same arguments never being honest and saying you could lose it all -- then many elderly do. I'm not old enough yet to fall for your number game.
It was also like listening to so many investment advisors who set out simple but fatally flawed ways to invest because most people of all ages don't look past the shell game they play with numbers like in your post.
Once again. Whether the asset appreciates or depreciates is an absolutely irrelevant factor in the decision of whether to finance or not.
If you think that it is relevant, post the math. Quantify the amount of difference it makes in each case.
