The first part to understanding loan refinancing is to know your ABC’s:
An A Paper Loan signifies that you qualify for a normal mortgage under the guidelines for Fannie Mae and Freddie Mac.
A B Paper Loan signifies that you do not qualify for a normal mortgage through Fannie Mae and Freddie Mac. Borrowers in this category are usually those with serious credit difficulties, such as a recent declaration of bankruptcy, or those who will not be able to afford the payments on a normal loan, or who have no way to document proof of their ability to pay.
A C Paper Loan means that you have bad credit and a collections agent has been hired in case you fall behind on payments.
An FHA Refinance is considered an A Paper Loan that has the credit requirements of a B Paper Loan.
Subprime loans (B, C and D Paper Loans) are intended for homebuyers who need mortgages but do not yet meet the requirements for an A Paper Loan. Unfortunately, the trouble that led to the subprime mortgage crisis stemmed from people applying for subprime loans to buy houses they couldn’t afford, and were unable to pay after several years because of high interest rates.
