as i have borrowed 6 lakh from icici during dec-06 at 9.25% for 20year. now the interest rate is 11.75% and tenure to 25years, because of heavy interest amount, i made part payment of 3 lakh. now tenure has come down to 6 years. can i make full payment and sit down? because i am afraid of interest rate going up, because when i took 6 lak at 9.25% i got to pay 12.37 lakh in 20 years, when it went to 11.75% i got to pay 18.57 lak in 25 years.
