This has worked well for me over the past couple of years. On the back is a message from the family to the people they are notifying of the address change. This side has my picture and logo on it and a message that tells their friends that if they ever consider a move Jerry Fowler would be someone they would recommend handling the job. This is a very inexpensive way to get you name out. Finally, you've got to find a way to track your marketing efforts or you'll go broke.
Different things work in different markets.
You want to quickly discover which marketing avenues pay off for you and which don't. Once you know what works, you can rest assured that your marketing dollars are well spent. When a call comes in, I know immediately where the potential buyer heard about my listing. Each month I create a marketing report that tells me the number of calls I received from each source. I remember one time I had a small town newspaper come to me preaching about how many people they reached and how effective their paper was.
