There are different ways of repaying (or repaying) a mortgage loan. The way depends on the periodicity of the fees (normally paid each month) and the variation of their amount over time (if they are constant, increasing or decreasing). Another potential option is to establish an initial period of denial, during which the capital is not returned only interest is paid, or nothing is paid.
Most often, loans received from credit institutions are returned through the payment of constant periodic fees (every so often, usually every month), in which amount a portion of interest and part of capital is included. This method of return is known as the "French system"
