Post cards

[Mikey Cas]

Hi guys, I have heard that sending out postcards is an effective way to reach out to potential investors that may want to unload some properties that are headaches for them. What is the best way to do this? I am sure there are many different ways, But, as a starting point....is there a way I can get a directory of landlords and thier addresses?? Or do most people just sned out hundreds of post cards to everyone in their area?? Thanks in advance for any insight.
