It’s not about the forms, or the lack thereof. It is about the fact that the contract entered into between the lender and the buyer, supported by explicit laws addressing the way lenders and buyers have to behave, has been breached.
What I see happening is that everyone wants the head of the buyer when they broach the agreement.
But you, explicitly, are arguing that for CONVENIENCE, the lender must be allowed to break the law AND the contract with impunity.
You apparently do not care if laws are broken, as long as you are not inconvenienced. Convenience is a fickle an unforgiving god, FRiend.
