If inflation takes off into double-digit land where It will go if we don't get the Feds under control, that loan may well be a bargain 30 years from now. They could pay it off from the petty cash drawer.
See Wiemar Germany.
I’ve made a bet that way, pulling as much cash as I could out of my house, re-fi at 3.75 fixed for 30 yrs. Hope to pay it back with Baraqqi/Bernanke/Geithner minibucks.
