One person bought a house 10 years ago for 450'000 TL. 15% was paid in advance, for the rest, a 30-year maturity mortgage loan was obtained, with 10% of them operating on a monthly basis. Interest rates have fallen and the person wants to replace his loan with a low interest loan. The new interest rate is the monthly execution of 5% per year. What amount will be saved if one replaces the remaining twenty-year loan with a new one?
