its pretty simple. I had my CSP swiped at a Subway for $30. I was in bed still and saw it. I called Chase immediately, they stop my card and told me they send me a new one. After that, a $600 charge for LegoLand tickets came in, i called chase again, they said they know and there is nothing to worry about. When the new card came, every got corrected. Easy process makes your mind calm. :]
I dont think you can do what your trying to do. Moving your mortgage from company to CC doesnt work that way. they see mortgage as a different kind of debt. which is why Visa and Amex doesnt allow using their credit cards to pay for mortgage. Only Mastercard and Discover has not said anything about it yet.
Pro: everything is on one screen. You can see everything.
Con: you will be using the old layout, not the new one. Although your old personal login will still work and show the new layout. Ppl has issues with Chase Pay but it works fine for me, if it doesnt work for you, there is always the personal login available to use.
