Is the information in the Delivery Specification published on Freddie Mac and Fannie Maes website the same?
Yes. The information in the jointly developed Delivery Specification is exactly the same for both GSEs. In June 2010, Freddie Mac and Fannie Mae published individual GSE-specific Implementation Guides for Loan Delivery Data that provide the GSE-specific valid values and conditionalities for certain data points that reflect the unique business terms and system requirements for each GSE.
