Paying a mortgage with a credit card isn't simple, but it can be done. It can be appealing to charge mortgage payments to a credit card. After all, it's likely your largest recurring expense — or one of your largest — each month. You may dream of racking up rewards points or simply need to keep cash handy for other expenses.  Unfortunately, mortgage lenders don't usually accept credit-card payments directly. However, you may be able to use a third-party service to complete the transaction.
