We were talking about rental property. If I was a slum lord with 10 properties and some being residential and others commercial, I'd be i a LLC so thats commercial. So if I had money leveraged for those properties, its not a personal mortgage. Its a commercial loan and those are more callable. They may have changed those banking practices but 5 years ago it was quite common.Again, a callable loan is not a mortgage. Additionally, a personal loan is not a mortgage.
A bank cannot call a mortgage just because they want to as you claim.
For your benefit from your source:
"Callable loans are usually short-term arrangements issued to brokerage firms and businesses who need a temporary capital infusion, but some personal loans do contain call provisions."
AT NO TIME WAS I TALKING ABOUT A PERSONAL MORTGAGE.
But those can have Call provisions in them also.
