Question: what is the difference between fannie mae do and du?
Answer: Before we submit every loan, we first MUST get an “automated approval” from “DO” or “DU” (Fannie Mae's “Automated Underwriter”), or from “LP” (Freddie Mac's “Automated Underwriter”). “DO” stands for Desktop Originator and “DU” stands for Desktop Underwriter – both names are used interchangeably and mean the same thing.
