When you receive your sanction letter, it is important to carefully review the terms and conditions of the loan. If you are satisfied with the terms, you must then confirm your acceptance by sending an acceptance letter within the specified time period, which can range from 1 to 3 months after receiving the sanction letter. This communication is crucial in finalizing the loan agreement and ensuring a smooth borrowing process. It is essential to adhere to the given time-frame to avoid any delays or complications.
