So even though CreditKarma shows Transunion and Equifax already, I need to just get those credit reports from AnnualCreditReport.com?Yes. You should get your free credit reports from Experian, TransUnion and Equifax.
You might find you must buy for cash a cheap used car from a private seller. DO NOT DO THIS WITHOUT a trusted mechanic’s INSPECTION first. You can drive this car until you can build up your credit.
Otherwise you will have to use a co-signer or find a lender willing to take a risk - but the latter means you probably be paying a high interest rate.
And if I had enough cash to buy a cheap car, I would have already done that. Heck, I would have fixed my 2010 Hyundai that is still sitting. Driving Uber is not profitable but it keeps money coming in and allows me to pay my rent and a few other online monthly business expenses.
