That's what the dealer said ? If so, I think they're lying to you. First, the dealer does income checks multiple times a day so I doubt they'd mess that up. Second, your credit score determines the interest rate to a very large degree, not your income level. Yeah, there's some combination of these things to some degree too..... In the end, I see it's finally settled, with a slightly lower sales price, and a lower interest rate, so it definitely improved for you.they figured out the number they put for my income was higher than my pay stubs (which I provided) and so the bank kicked back the loan and was requiring a higher interest rate.
