I would think you should try option 2 and if that fails then option 3. I don't think you'll get anything positive with option 1 as it'll just show as "paid as agreed".
My brother has an auto loan with Capital One that has almost always been deliquent (long story).
He's seven months away from it being paid off. For optimal credit rehabilitation, should he:
1. Pay it off (has the means to now)
2. Attempt to use the early pay off as leverage for goodwill of some sort
3. Pay the last 7 payments all on time
Thanks for all your wisdom!
I agree with the other poster. If he has been delinquent, option one and three does not change anything nor improve his circumstances. His best option is number two.
