It's pretty hard to sell a vacant home unless it's already something that's highly desirable and affordable. Depending on the price range and other homes available, it may be worth it to stage at least two rooms in the home.
Usually it's easiest if the seller can leave a set table in the formal dining room - they probably won't be using this in their new house right away... a few armchairs and side tables in the living room - they can live without these for a little while... and optimally their bed, fully made, in the master bedroom if possible (tough to live without, but tougher to make 2 mortgage payments for 9 months.)
