According to Anglo-American property law, a mortgage occurs when an owner (usually of a fee simple interest in realty) pledges his or her interest (right to the property) as security or collateral for a loan. Therefore, a mortgage is an encumbrance (limitation) on the right to the property just as an easement would be, but because most mortgages occur as a condition for new loan money, the word mortgage has become the generic term for a loan secured by such real property. As with other types of loans, mortgages have an interest rate and are scheduled to amortize over a set period of time, typically 30 years. All types of real property can be, and usually are, secured with a mortgage and bear an interest rate that is supposed to reflect the lender's risk.

Mortgage lending is the primary mechanism used in many countries to finance private ownership of residential and commercial property (see commercial mortgages). Although the terminology and precise forms will differ from country to country, the basic components tend to be similar:

Property: the physical residence being financed. The exact form of ownership will vary from country to country and may restrict the types of lending that are possible.
Mortgage: the security interest of the lender in the property, which may entail restrictions on the use or disposal of the property. Restrictions may include requirements to purchase home insurance and mortgage insurance, or pay off outstanding debt before selling the property.
Borrower: the person borrowing who either has or is creating an ownership interest in the property.
Lender: any lender, but usually a bank or other financial institution. (In some countries, particularly the United States, Lenders may also be investors who own an interest in the mortgage through a mortgage-backed security. In such a situation, the initial lender is known as the mortgage originator, which then packages and sells the loan to investors. The payments from the borrower are thereafter collected by a loan servicer.)
Principal: the original size of the loan, which may or may not include certain other costs; as any principal is repaid, the principal will go down in size.
Interest: a financial charge for use of the lender's money.
Foreclosure or repossession: the possibility that the lender has to foreclose, repossess or seize the property under certain circumstances is essential to a mortgage loan; without this aspect, the loan is arguably no different from any other type of loan.
Completion: legal completion of the mortgage deed, and hence the start of the mortgage.
Redemption: final repayment of the amount outstanding, which may be a "natural redemption" at the end of the scheduled term or a lump sum redemption, typically when the borrower decides to sell the property. A closed mortgage account is said to be "redeemed".
