Looking for sellers to target besides absentee owners. Advice?

[Jonathan Studdard]

My business partner and I are looking to start generating leads in our area with mail. However, we know absentee owners are probably getting blown up with other mail. 

We plan to get on listsource and mail absentee owners with 50-70% equity in the property, but I know there are other events like tax liens, divorce, etc. that cause people to want to sell. We'd like to target some of those as well, but aren't sure how to go about putting a list like that together. 

We want our mailers to speak to the problems of the type of sellers we are targeting, and we want to think outside the absentee owners box. Who do you mail and how do you generate your lists? 

Any advice is much appreciated.
