Are FHA record retention requirements different for documents with electronic signatures?

FHA’s record retention requirements are the same for both ink and electronic signatures. 
Mortgagees must maintain their origination case binders in either hard copy or electronic format for a period of two years from the date of endorsement.
Mortgagees must retain all servicing files for a minimum of seven years after the transfer or sale of the Mortgage or termination of mortgage insurance.   For cases for which a claim is filed, the Mortgagee must retain documentation in compliance with the Claim Review File section for at least seven years after the final claim or latest supplemental claim settlement date.
