Wholesaling - Listsource.com, Courthouse, Other?

[Dustin Morgan]

Good afternoon, BP.  I'm looking for your preferred medium to obtain data that has been helpful in your wholesaling experience.  My specific plan is to send postcards to home owners in more rural areas outside of the St. Louis City.  I'm currently filtering my sources to unoccupied, tax liens, between $100 and 250k with equity 25% - 100%.  I'm looking for advice on steps to move forward and any secrets or advice some of you may have.  Feel free to offer any alternative methods than those listed as I am new and interested in the best routes both online and in person that have led you to closing wholesaling deals.  I'm just as interested in what not to do.  Thanks ahead of time.  - Dustin
