Add a great interest rate environment.
The Federal Reserve is holding short rates near zero.
The Fed purchased and now holds well over one trillion dollars in Fannie Mae and other mortgage-backed securities. This helped keep long rates down until the market for loan-back securities, devastated by the credit crisis, rebuilt.
