The Trump administration is considering selling the US government's stakes in Fannie Mae (FNMA) and Freddie Mac (FMCC) through a public offering that could raise $30 billion. Yahoo Finance Senior Markets and Data Editor Jared Blikre explains what public trading of the mortgage giants would mean for investors after years of government conservatorship.

The Trump administration is reportedly looking to sell stock in Freddie Mac and Fannie Mae, which could be valued at roughly $500 billion.

A potential offering would value the two mortgage giants at around $500 billion and involve selling 5 percent to 15 percent of their stock.
