Subprime mortgage and real estate crisis


Definition of subprime mortgage


The subprime is a type of mortgage that is normally made out to borrowers with lower credit ratings (often below 600). As a result of the borrower's lowered credit rating, a conventional mortgage is not offered because the lender views the borrower as having a larger-than-average risk of defaulting on the loan. Lending institutions often charge interest on subprime mortgages at a rate that is higher than a conventional mortgage in order to compensate themselves for carrying more risk.


ARM (adjustable rate mortgage)


There are several different kinds of subprime mortgage structures available. The most common is the adjustable rate mortgage (ARM), which initially charges a fixed interest rate, and then convert to a floating rate based on an index such as LIBOR, plus a margin.
ARMs are somewhat misleading to subprime borrowers in that the borrowers initially pay a lower interest rate. When their mortgages reset to the higher, variable rate, mortgage payments increase significantly. This is one of the factors that lead to the sharp increase in the number of subprime mortgage foreclosures in August of 2006, and the subprime mortgage meltdown that ensued.

Many lenders were more liberal in granting these loans from 2004 to 2006 as a result of lower interest rates and high capital liquidity. Lenders sought additional profits through these higher risk loans, and they charged interest rates above prime in order to compensate for the additional risk they assumed. Consequently, once the rate of subprime mortgage foreclosures skyrocketed, many lenders experienced extreme financial difficulties, and even bankruptcy.
