Identifying motivated sellers who appear on multiple lead lists?
I have been pulling some really great lists of motivated sellers of whom I will be sending direct mail. I am trying to identify sellers who have a higher level of motivation to sell than others by finding names and addresses that appear on multiple lists I have pulled. Is there a platform out there or a system I can use to identify these names that are on 2, 3, 4, or more of my different lists just by plugging in the names and addresses? I want to target sellers who appear for example on all 3 of the tax delinquent, absentee owner, and pre foreclosure lists I have pulled. Any advise?
