Banks calling notes due?

[Ki Lee]

How many of you had banks call note due on the loan when you transferred the rental property into LLC? I know it's supposed to be rare, but just wondering if it happened to anyone. And if so, what happened? Did you have to refinance at the current rate or just put the property back in your name? I have mortgage with one of the major banks. How often do big banks sell loans to another company where they find out about the transfer of interest?
