I might take a different approach. Having owned a mortgage company for many years, I am always less comfortable with the more eyes that need to see a file. Typically, a loan will go to "regional" for larger loan amounts,property types, etc. Also, the word "regional" can mean "outside investor". Again, you have a whole new set of eyes. Eyes that are typically more conservative. My advise is to be persistant with your mortgage contact and let the process play out. Good Luck.
That does not necessarily mean bad news. More importantly, if the situation may seem unusual or the loan officer is making it appear that way you need to ask them specifically why it has to be sent to a certain place or is getting special attention. All loans have to be seen by underwriters not sure why this would be a special situation. I would try to find that out....
