Everyone does open houses, and most agents have a traditional approach to the process.
Typically an agent will determine a date and time, place an ad in the Sunday paper, put out the open house sign and wait in hopes someone will show up.
I prefer to use the open house as a marketing opportunity and like to get pro-active to make sure that the event gets the maximum exposure possible.
