Sellers never know how long their property will be on the market, so opportunities to reduce costs while a house is for sale are welcome. One idea is to let your stager know if you have furniture available to use for staging. Even if you are moving and the house will be vacant, there may be items you could leave and move at a later date. This could reduce the cost of monthly rentals while the house is for sale. Of course not all furniture is suitable for staging, and it's important to trust your stager's judgement about what to use (or not use), since they are knowledgeable about how to make property appeal to potential buyers, and a quicker sale will save you the most.
Shown below is a home where furniture available from the owner was suitable for staging, with rentals and accessories also used to complete the look.
