I notice they do not accept VISA for mortgage payments anymore. It appears previously scheduled VISA payments will go through, but a warning notice appears if you try to change the date of a previously scheduled VISA payment.

With their 2.5% fees, there are few cards for which this is worth using. A 5% GM Mastercard is still a possibility, but this pay off only when and if a GM car is bought (and the points expire), and for me that is too uncertain to make using that card useful this way.
