The following image below is a sample of the sign or standard riders that will be optionally available for purchase once you are a customer. These signs are affordable, reliable and reusable since the property codes that come with your plan are reusable.
When you list a new property, you simply pick which available property code (i.e. CS3378) you want to associate. Then take your sign and prop it in front of your property.
After that, prospective home buyers passing by can simply get the info by following the instructions on the sign.
