Not sure if anyone got lucky enough to have a mortager/auto loan company allow payments via a credit card, but neither of mine do. They only have options to draft the payment from a bank account. With that being said, is there any backdoor way to do this? I think a cash advance on the credit card may be an option, but those can be expensive and not worth it. I’ve also heard of the AMEX BlueBird system. Has anyone used this?
