Glossary of Real Estate Terms

margin
The difference between the interest rate and the index on an adjustable rate mortgage. The margin remains stable over the life of the loan. It is the index which moves up and down.

maturity
The date on which the principal balance of a loan, bond, or other financial instrument becomes due and payable.

mortgage
A legal document that pledges a property to the lender as security for payment of a debt. Instead of mortgages, some states use First Trust Deeds.

mortgage banker
For a more complete discussion of mortgage banker, see "Types of Lenders." A mortgage banker is generally assumed to originate and fund their own loans, which are then sold on the secondary market, usually to Fannie Mae, Freddie Mac, or Ginnie Mae. However, firms rather loosely apply this term to themselves, whether they are true mortgage bankers or simply mortgage brokers or correspondents.

mortgage broker
A mortgage company that originates loans, then places those loans with a variety of other lending institutions with whom they usually have pre-established relationships.

mortgagee
The lender in a mortgage agreement.

mortgage insurance (MI)
Insurance that covers the lender against some of the losses incurred as a result of a default on a home loan. Often mistakenly referred to as PMI, which is actually the name of one of the larger mortgage insurers. Mortgage insurance is usually required in one form or another on all loans that have a loan-to-value higher than eighty percent. Mortgages above 80% LTV that call themselves "No MI" are usually a made at a higher interest rate. Instead of the borrower paying the mortgage insurance premiums directly, they pay a higher interest rate to the lender, which then pays the mortgage insurance themselves. Also, FHA loans and certain first-time homebuyer programs require mortgage insurance regardless of the loan-to-value.

mortgage insurance premium (MIP)
The amount paid by a mortgagor for mortgage insurance, either to a government agency such as the Federal Housing Administration (FHA) or to a private mortgage insurance (MI) company.

mortgagor
The borrower in a mortgage agreement.
