Getting a "wow" means you went beyond their expectations.  Each client has a different wow factor because they each have a different relationship with you.  It takes some thought and time, but after closing, I visit them at their new home (buyer) or send to their existing home (investor)  a custom basket of products that were 'things' we talked about during the real estate process.  They are always shocked that I was listening and I always get a "wow".  Carolyn Koskan, PB Utah and Idaho.
