Do not use Combo Lockboxes on GFC CMLS listings

The GFC CMLS does not support combo lockboxes, nor do we recommend using a combo lockbox on your listings. It has come to our attention that people are using combo lockboxes to access vacant homes and steal the copper piping. The GFC CMLS only supports electronic lockboxes because they maintain an audit trail of who has accessed the lockbox. Combo lockboxes do not have this security feature.
