Who Is Marketing With Virtual Tours

We are currently photographing more virtual tours for businesses and apartments than for homes.  These commercial customers search out virtual tour photographers on the internet where they find us to shoot their properties.  I don't know why more realtors don't use virtual tours to sell their homes.  It is our experience that those who add a tour to their marketing sell their properties faster.  I'm sure the principle of turnover of inventory to improve profits is as valid in real estate as it is in retail sales and improving turnover would be a universal goal of realtors.
