An empty room feels cold and uninviting and actually appears smaller with no furniture, especially in photographs. Furnishing an empty room not only gives potential buyers some perspective to the actual size of the room it also can give a feeling of warmth and comfort. . Staging a vacant home is well worth the cost as it will appear significantly more welcoming and help the buyer to imagine themselves in this space.  If your budget doesn't allow the whole house to be staged the most important rooms are the living room in #1 spot and master bedroom as #2.
