If you want to avoid bridging even for a few hours or days then it should be possible to shift all furniture using a professional company, but if you are going it alone with a van then it may take a day or 2 to shift everything so if you might have to bridge in this case, or maybe start moving the small stuff to friends / family houses and only move the big stuff on the day of closing. Facing a similar dilemma myself soon except I need floors put in before bringing 1 year old into the new house!
