Zero, Zilch, Nada, Nothing
Fannie Mae (and Freddie Mac) have already paid more money back to the federal treasury in the form of preferred dividends than it received during the bailout, so taxpayers have made a profit on the bailout. The federal government disbursed ~$187 billion to bail out the GSE's and the GSE's so far have paid back ~$225 billion, making for a tidy
$38 billion profit for the taxpayers which will continue to increase as treasury will continue to receive a nice 10% preferred dividend for the foreseeable future.

Additionally, the workers at Fannie were simply paid the salaries that were owed to them for the work they did an continue to do. They obviously continue to have jobs at Fannie because Fannie was not allowed to fail by the government, but most of the people I know working on CU and the UCDP would have little trouble finding good jobs elsewhere.
It is more than a little bit ironic that a residential appraiser would question whether Fannie employees are beneficiaries of the government bailout of the GSE's when
most of the income made by a typical residential appraiser is due to the demand for appraisals generated by GSE, FHA, and VA requirements. I wonder how much work you and most other residential appraisers would have been left with the past 7 or 8 years if the government had simply let GSE's go under and let the entire secondary mortgage market system in this country collapse (the answer is not much). I also wonder how much less work most residential appraisers would have had over the past few years if not for several refinance runs that would not have occurred if the Fed had not subsidized mortgage rates through multiple rounds of quantitative easing (QE). Whether or not one thinks that the GSE bailouts and QE were good policy, few benefited more from these programs as a group than residential appraisers.
