<prompt> Human: Hi all,Id like to use my credit card to pay off my mortgage faster. Basically, I want to pay a big chunk of the principal, and then put my entire monthly income towards the credit card balance. What are the best credit cards to do this? Should I be looking for those that offer the highest cash back rewards? Was thinking to go with the Chase sapphire preferred card, as that seems to best the most popular...  <response>: Are you sure you can pay your mortgage using a credit card? The only way I know of would be to do a cash advance, which would not be worth it IMO.
