Tom is correct. It all depends on the lender and what the underwriter finds or doesn't find in the file. Best case scenario is that the underwriter doesn't need anything more for the file or doesn't find anything that will stall the file. It used to take 3-4 days for the underwriter to clear the file, now it's not unusual to take 2-3 weeks. Hopefully, you will only be delayed for a week or so and then ready to go into the closing department. Good luck!!
