Yeah, I did that on purpose. I bought another car in January so I've had two loans since then. I didn't want to take the hit for having a high balance to loan ratio so I've been carrying the first loan as long as I can. I made my last full payment yesterday. The final payment would have been about $20 but I paid it down to 99 cents... just because. My total loan balance will be at 95% after the first loan is paid off. Courious to see what that will do to my scores.
Wouldn't be surprised if you received a letter thanking you for paying off your loan. Depending on which lender they may just do an account adjustment for the $.99 and zero balance the account.
Yeah, companies tend to write off small balances like that. I love the strategy as I'm doing pretty much the same thing. With a 1.9% loan my next payment is not technically due until 9/2022 and I've brought the balance down to 20%, will probably bring it down to 1% by the end of the year and let it ride until my MTG re-fi done in 8/2018 drops another 20K or so as I'm paying extra principal on the MTG. Current combined loan balances = 73.5%, which seems sufficient for my profile to hit 850.
