Owners, residents, shareholders and tenants alike in luxury buildings expect and deserve and the same "white glove" service that is found in 5 Star Hotels. There is only one reason why they don't get it. Building Services staff(s) are rarely formally trained in interpersonal and resident care skills.
All sales teams need refreshment and renewal from time to time. Don't let yours fall into that comfort zone of selling the way they always have. Buyers and renters have grown much too savvy.
If you are a builder, developer, sales / marketing company or property management company you have a huge investment. Don't let it suffer due to poor performing staff members. Have them evaluated periodically.
