Subprime Mortgages
 A mortgage granted to a borrower considered subprime, that is, a person with a less-than-perfect credit report. Subprime borrowers have either missed payments on a debt or have been late with payments. Lenders charge a higher interest rate to compensate for potential losses from customers who may run into trouble or default.

Jumbo mortgages
In the United States, a jumbo mortgage is a mortgage with a loan amount above conventional conforming loan limits. This standard is set by the two government-sponsored enterprises Fannie Mae and Freddie Mac, and sets the limit on the maximum value of any individual mortgage they will purchase from a lender. Fannie Mae (FNMA) and Freddie Mac (FHLMC) are large agencies that purchase the bulk of U.S. residential mortgages from banks and other lenders, allowing them to free up liquidity to lend more mortgages. When FNMAand FHLMC limits don't cover the full loan amount, the loan is referred to as a "jumbo mortgage". The average interest rates on jumbo mortgages are typically higher than for conforming mortgages.



Fannie Mae
The Federal National Mortgage Association, commonly known asFannie Mae, was set up as a stockholder-owned corporation chartered by Congress in 1968 as a government-sponsored enterprise (GSE), but founded in 1938 during the Great Depression. The corporation's purpose is to purchase and securitize mortgages in order to ensure that funds are consistently available to the institutions that lend money to home buyers.

Conventional Loans
A mortgage conventional loan is a lender agreement that's not guaranteed or insured by the federal government under the Veterans Administration (VA) the Federal Housing Administration (FHA), or the Rural Housing Service (RHS) of the U.S. Department of Agriculture. Although a conventional loan is not insured or guaranteed by the government, it can still follow the guidelines of government sponsored enterprises (GSE's) such as Fannie Mae or Freddie Mac as both Fannie Mae and Freddie Mac are stockholder-owned corporations and are not part of the federal government.

Adjustable Rate Mortgages

A mortgage with an interest rate that may change, usually in response to changes in the Treasury Bill rate or the prime rate. The purpose of the interest rate adjustment is primarily to bring the interest rate on the mortgage in line with market rates. The mortgage holder is protected by a maximum interest rate (called a ceiling), which might be reset annually. ARMs usually start with better rates than fixed rate mortgages, in order to compensate the borrower for the additional risk that future interest rate fluctuations will create.
