I got pre-approved for a 100% USDA mortgage last month and made an offer on June 4th. I completed all the paperwork with the mortgage company on June 10th. My realtor told me last Thursday that we were almost ready to close that the loan was submitted to underwriting. I left a message with my mortgage company to see where we were at and they left me a message only telling me that it was in underwriting. How long does it typically take in underwriting?
