Principle and Interest Loan

Where a mortgage allows for the repayments to pay the interest due on a loan, together with part of the principle, or the original amount borrowed. The repayments say constant, [if fixed interest, or vary with the market forces if variable], but because the amount owed is reducing, more and more principle is paid with each repayment, until the mortgage is finally paid out. Mortgage terms are usually set between 10 and 30 years for this type of loan. The repayment of the loan follows a gradual curve, that steepens as more of the loan is paid out. This is the most common style of loan for mortgages.
