Hi there ...
so sorry for your situation. Wells Fargo, in my opinion, is one of the worse in closing times. I as a mortgage broker, and lender in all 50 states, have the ability to rush a file BUT 203k loans do have some additional paperwork. Have you researched and gotten a registered contractor to work with? If all of your team, i.e., realtors, contractors, etc would move expeditiously it can be saved. Oct 22nd is your close date so that is less then a month. I think you have to make the decision if you want to persue it and rush like crazy to get all done that needs to be done. Get appraisal done asap, general contractor in to give a good estimate / cost breakdown and zoom zoom with anything else you may need documentation wise.
