Mortgages first appeared in the English feudal system and have continually served as a means to obtain land ownership without paying for the total price of the land. The mortgage is essentially a contractual relationship creating an interest in land, but it is not a loan as many people often confuse it. Most mortgage agreements involve a promise to repay a debt, but is not a debt in itself, but rather, is evidence of a debt. Essentially, the mortgage is a transfer of either a legal or equitable interest in the land on the condition that the interest will be returned when the terms of the contract are performed. If the borrower fulfills all of the obligations of the mortgage contract, the transfer then becomes void and title automatically passes back to the mortgagor.
