Dear Mr. Deepak,
Thanks for the reply.
Well, I don't know if I fully understood you. I took the loan because I had no money. Now I have the property for which I took the loan and I want to sell it. I still have no money so how can I repay the loan before selling the property. I can repay but only after I receive money from the buyer. Isn't it? Based on what you have written I can never sell my property till I have money in hand to repay my loan. I doubt this is the case or I mis-understood.
As I know there is a kind of agreement that allows the owner to sell and repay the loan after the sale. Or probably buyer is paying a part of the deal to the bank and rest to the seller. These scenarios look more realistic too.
But my question is not about repayment but about penalty. I have no probelm to reply the loan but why should I pay the penalty. Keep in mind that repayment in case property is sold is must so there should be no penalty for something which is must do.
On the other hand, repayment of full or part loan without selling the property is optional that a borrower may opt for or not. And then I can understand (though I still do not agree, but that is something else :-)) that banks charge penalty in this case.
