Mortgage finance for an interest only loan is a temporary state. In other words there is a designated period of time that the borrower is not required to pay against the principal of the loan. The principal is still accruing interest and at some designated point in time the borrower will be required to begin making payments against the principal or pay the entire principal in a balloon payment. At the point the loan requires normal amortized payments the monthly payment amount is usually dramatically higher than the interest only payments. Many borrowers refinance an interest only loan before amortization payments begin. Mortgage finance with amortized loan payments each month is more common. This type of loan applies part of the payment toward interest and part toward principal. A mortgage calculator that displays results in an amortization table will show the breakdown of each payment.
