However, if the principal repayment is higher than the outstanding amount payable on a specific installment, the balance amount outstanding shall be recalculated using the finance concepts taking into account the present valuePresent ValuePresent Value (PV) is the today's value of money you expect to get from future income. It is computed as the sum of future investment returns discounted at a certain rate of return more of the balance loan amount discounted at the rate of interest.

Thus there is a thin line that defines the difference between mortgage recasting and refinancing.
  • Under the terms of the former, the borrower makes lump-sum payments making himself or herself ahead from the stated schedule of repayment, and the lender rescheduled the principal balance amount outstanding being the amount lower in terms of annual interest payment, number of years of repayment, and annual repayment of principle, while in the later, transfer of loan takes place where the new lender has been transferred the loan from the old lender and the further repayment is to be done to the new lender only as per the new terms of the loan.
