Though this may be a bit of a silly issue, a good tip when going through the lockbox process is to not abuse it. In 2010 a Standard of Practice was added to article 3 in The Code of Ethics saying realtors can not give access to properties listed except as those made by the listing broker or owner of the property. Hence, as a realtor, do not give out the lockbox code to your clients and allow them to view the property without their realtor or their realtor will be in violation of article 3. This avoids the clients from entering an awkward and embarassing situation if they walk into an owner occupied property without a realtor. A realtor can get into big trouble with the association he or she is a part of and with his or her lockbox vendor. Remember that even if they buyers are under contract to purchase the home and this is not a first showing, the clients will still need permission to enter the home and must be with a realtor when entering. This is a good tip to avoid complaints from the property owner or listing broker and to keep your clients thinking highly of their realtor.
