8. What is a lock box and is it required? 

The Key Safe or Lockbox placed on the home is a secure method of controlling and monitoring visitors.  Only after a authorized user inserts their Keycard and their Pin number will the Lockbox release the key.  The Lockbox records the Date, Time, and the Identity of the Keycard holder requesting entry.  This record is kept electronically in the Lockbox and can be read at anytime by the owner of the Lockbox.  Occupants of the property should require all visitors to release the key from the Lockbox and produce a business card.  All legitimate agents will have a Keycard and a business card.
