The interest rates for Home loan are calculated either on Fixed rate or Floating rate of interest. The type of interest to be charged is agreed before the loan disbursal and EMI are computed basis the agreed interest type. During the loan tenure, if borrower wish to change from Fixed ROI to Floating ROI or vice-a-versa, it is possible. Few Banks and NBFCs allows to switch, but post completion of minimum months or years as per loan terms and conditions. Lender might also charge borrower with loan switching fee, so do compute the charges before making a switch.
