The property I have in my mind is currently held by a private motivated seller who just wants out of the game.  

Each time I listen to a BP podcast I find myself with even more motivation than before. 

It would depend on your motivation in my opinion.

Sure, it's a stretch, but the more motivated they are, the better you can create a relationship, the more your chances improve.  

Your top priority is to make the phone ring with motivated sellers.

this leads me to believe 2 thingsA) no one is "motivated" in my marketB) the information on preforeclosures/tax liens is not accurateif there is a better way to generate these leads in listsource it would be appreciatedif there is a better source of leads it would be appreciatedWould I be better off just hitting the courthouse?

Im about to start another direct mail campaign and I'm wondering what is the best type of mailing to get the most motivated seller leads.

-If I'm good at finding deals or have a motivated seller, there's a good chance I'll be purchasing below the appraisal value, correct?

If the seller is truly motivated they will want some cash and be done. 

Part of the motivation in the IRS serving levies is to bring the taxpayer into compliance (ie unfiled tax return 2014).
