Yes, it is very possible to transfer the $3k onto a credit card. You just need to make sure that the credit card company will allow the transfer from a mortgage. Also, you usually have a 3% balance transfer fee ($75 max for some cards). But overall, it will save them a considerable amount over time. Just remember, that the monthly payments on a credit card will be higher than the payments from the mortgage, so as long as they can afford the payments still, it should be fine.
