The Mortgage Commitment Waiting Game

Yesterday, I received a telephone call from my attorney, who informed me that the sellers are requesting information regarding the mortgage commitment. Apparently he's getting a lot of push back from the sellers attorney. I explained that I haven't heard  from HSBC in the past week. In fact, my five telephone calls to the loan officer went unanswered. My attorney suggested that I send an email to the loan officer letting her know the urgency. I called the loan officer and to my surprise she actually answered the phone. I relied the information regarding the urgency of the matter and she agreed that my frustrations were warranted, However she says, my file was no longer with HSBC but with the underwriter. She suggested that I write an email detailing the urgency, which she would then forward to the underwriter. I wrote the email and sent it to the loan officer, copying it to my attorney. At about 8:49 pm, I received a letter from the loan officer stating that the information was forwarded to the underwriter. Now we wait, again. Do I really want to continue with this process? At this point I'm not sure. Still throughout this entire ordeal I have been able to keep my composure and my sanity. But it has truly been one of the worst experiences of my life. The stress levels needless to say is very high.
