Manually Underwritten v DU for Fannie Mae
What is the difference between the underwriting called "manually underwritten" and "DU" for fannie mae loans? In looking at the fannie mae website it says that manually underwritten loans are maxed out at six, but DU (don't know what that means) underwriting can have ten. Can someone please explain what these are or how to find out more information on them? Does either way effect the interest rate of the loan?
