<prompt> Human: Ok let me start out with saying I make SOME money, unfortunately I dont make enough monthly for an apartment. I have 2 cars. One is my daily driver, the other is a pile of shit I call my racecar even though its not fast and wont race. But hey, it has serious emotional value. I also have shit credit. Im 21, no credit card, and a disagreement with Aurora healthcare about them never contacting my health insurance company even though I told them MULTIPLE times... Not the point I have 0 debt at 21, this means I have 0 or worse credit. Unfortunately everything I could ever want in life is worth no more than 2 months salary exept for a house and airplane I was going to take out loans 2000 once a year for upgrading my corrado it needs new paint, and might as well make it showroom ready unfortunately the corrado will remain a depreciating asset for another 5-10 years... So why not just take a loan out for investments, say a sp 500 company. Put one of my cars up for collateral. I mean I walk to work anyway, its not that big of a risk and pay off the loan. At least my money is going to an appreciating asset that pays dividends. I need to build my credit, but I dont like credit cards because there is nothing I need right away. Am I missing something?  <response>: I have 0 debt at 21, this means I have 0 or worse credit.Contrary to popular belief, you do not need to take on debt to build credit. The best and cheapest way to build credit is to get a credit card, use it for all your daily purchases, then pay it off completely at the end of the month. That way, every month, the card company will report to the credit bureaus that you have a small amount of debt and are making all of your payments on time; meanwhile you are avoiding all interest and fees. If youve never had any debt before you may have to open a secured card at first, but you should be able to upgrade to an unsecured card after a year or so of making on time payments.
