Use your best judgment. This is information to best guide you. There are situations where you are back and forth between the two states and it is a gray area. Apart from all other considerations, on what date did you consider yourself a Texas resident?
I had a similar situation when I moved from one house to another. For me, my residency ended the day the contractor entered to fix the house for resale. While I still owned the house for several more months, that was the day I was done with it.
