<prompt> Human: Posted in askreddit was advised here would be better--My friend was a first time buyer, I looked at his paper work and its broken down as belowPayment applied 225 his monthly paymentInterest taken 88Principal 136.20Previous balance 5352.71New balance 5216.15To me it seems he is paying 40 interest rate which seems really high. Although I might be wrong as I dont know too much about this. Is there anything he can do about this? Thanks!  <response>: Thats just the way the loan is structured.Via a process called amortization, a certain interest rate is charged, but the payment never changes.As the principal goes down, the amount paid toward the principal goes up.You start paying mostly interest and end paying mostly principal. Your friend can request the amortization table from his lender and you can see the breakdown from here to the end.
