If you get far enough behind in your mortgage payments, you'll probably find yourself facing a foreclosure. You'll receive a complaint, the first step in a judicial foreclosure, or another document, like a notice of default in a nonjudicial foreclosure, letting you know that the process has started.
In that initial document, you might notice that the foreclosing party is something like "U.S. Bank National Association, as trustee, on behalf of the holders of the Bear Stearns Asset-Backed Securities I Trust 2005-AC6." If you see this kind of language in your foreclosure paperwork, your home loan is part of a residential mortgage-backed security.
But what is a mortgage-backed security? In the most basic terms, a mortgage-backed security is a type of investment that's secured by home loans.
When you take out a loan to buy a home, the lender provides you with money to make the purchase in exchange for your promise to repay the loan plus interest. This promise, along with the terms for repayment, is contained in the promissory note.
As part of the transaction, you'll also pledge the home as collateral for the loan. The mortgage (or deed of trust) is the document that contains this pledge.
In a process called "securitization," multiple loans, including both the promissory note and the mortgage or deed of trust, with similar characteristics are pooled, often held in a trust, and then sold in the secondary market. The purchaser (or "investor") gets the right to receive a portion of the future income stream that comes from the borrowers' payments on the mortgage loans.
The key parties in the securitization process are:
A "pooling and servicing agreement" is the main contract that governs the relationship between these parties and controls what can and can't be done with a securitized trust.
With securitization, mortgage investors can better understand the price and risk of their investment because approved credit rating agencies classify the various tranches according to their relative risks.
Individual mortgages, on the other hand, are often difficult for investors to understand and price. And, when investing in mortgage-backed securities, an investor is insulated from the risk of an individual mortgage default.
Any type of mortgage loan can be securitized. During the housing boom of the early 2000s, subprime loans were particularly popular for securitization because they generated large returns for investors due to their high-risk nature.
The subsequent foreclosure crisis was due in significant part to residential mortgage-backed securities that were filled with subprime loans, which eventually had massive numbers of defaults. Droves of loan defaults in low-rated tranches, as well as in more highly-rated tranches, led to large losses for investors.
The securitization process is complicated. If you're facing a foreclosure and your loan has been securitized, consider talking to an attorney to help you understand the intricacies and issues surrounding securitization as it pertains to your individual situation.
A foreclosure attorney can also explain different options that might be available to prevent a foreclosure and can tell you if you have any defenses to the foreclosure, like the foreclosing party doesn't have standing.
