As a former Realtor Associate, I recall making suggestions to my Sellers on making their house more presentable for a prospective buyer. I also recall that it took a lot of effort and strategy to engage this potential client in a dialog that would ultimately turn from potential to "client".
Once a Realtor has accomplished this, do they want to risk telling their client that either the home smells from the cat box, or there are way too many personal photos in the living room, or the driveway needs to be power washed, etc, etc,???
This is where a Realtor can blame the Home Stager! The surveys and studies have proven that using a Home Stager causes a house to sell quicker and at a better price. But, trying to convince a home seller to pay for a home stager is often futile. As the Realtor, spend a small amount of money for a consultation and transfer all the blame for constructive criticism on the Home Stager. You might just get your listing sold quicker and receive a nice commission check. Why don't you consider making a Home Stager recommendation part of your listing presentation?? The initial consultation is minimal and it allows you to maintain your relationship with your seller.
Sometimes the Realtor pays for this and other times the Home Seller.
