If Fannie Mae and Ginnie Mac follow Freddie Mac’s lead into buying second mortgages, we estimate the secondary home equity loan market could exceed $3tn. By opening up the securitisation market for second mortgages, not only would more institutions be inclined to originate the loans, but the cost to borrowers would meaningfully decline with more finance providers. It would also provide big stimulus to an economy and consumer that appear to be slowing down without adding a dime to government debt. Rarely have I seen such a true win-win scenario for the government, Wall Street and the US consumer.
