Wholesaling specifically for personal buy and hold properties

[Matthew Gillespie]

First and foremost,  I apologize if this is in anyway a re post or redundant.  I tried to search the forums for this topic and was unsuccessful.  If anyone has any relevant links please share!

Basically,  I'm wondering if anyone on here has developed a direct mail or lead generation campaign specifically to purchase properties under market value for their personal portfolio.  I'm in the beginning phases of mapping out a direct mail campaign specifically targeting back tax, and absentee owners.  My current goal is to get them under contract and purchase them for a persona buy and hold portfolio, hopefully between 30-50% or more under market. Anyone using this strategy? Any tips or considerations?  Is there a good method for finding marketable leads? 

Thanks!
