A mortgage is the transfer of an interest in property (or the equivalent in law - a charge) to a lender as a security for a debt - usually a loan of money. While a mortgage in itself is not a debt, it is the lender's security for a debt. It is a transfer of an interest in land (or the equivalent) from the owner to the mortgage lender, on the condition that this interest will be returned to the owner when the terms of the mortgage have been satisfied or performed. In other words, the mortgage is a security for the loan that the lender makes to the borrower.In most jurisdictions mortgages are strongly associated with loans secured on real estate rather than on other property (such as ships) and in some jurisdictions only land may be mortgaged. A mortgage is the standard method by which individuals and businesses can purchase real estate without the need to pay the full value immediately from their own resources

Legal systems in different countries, while having some concepts in common, employ different terminology. However, in general, a mortgage of property involves the following parties.

Lender:-A mortgage lender is an investor that lends money secured by a mortgage on real estate. In today's world, most lenders sell the loans they write on the secondary mortgage market. When they sell the mortgage, they earn revenue called Service Release Premium. Typically, the purpose of the loan is for the borrower to purchase that same real estate

Borrower:-A mortgagor is the borrower in a mortgage—they owe the obligation secured by the mortgage. Generally, the debtor must meet the conditions of the underlying loan or other obligation and the conditions of the mortgage. Otherwise, the debtor usually runs the risk of foreclosure of the mortgage by the creditor to recover the debt.

Other participants:-Because of the complicated legal exchange, or conveyance, of the property, one or both of the main participants are likely to require legal representation. The terminology varies with legal jurisdiction; see lawyer, solicitor and conveyancer.
