YELLOW LETTERS expectations

[Christopher Gil]

Ok so I am pulling trigger on yellow letters from the .com site.  Sending to tax default absentee owners, code violation absentee and owner occupied with ownership history over 15 years, and evictions list in orlando.  I have seen anywhere from .5% to 15% response rate.  I have not seen anyone say ANYTHING about closing rate.  So my question is what is realistic to expect for response and from that response what would one expect to contract?  I am assuming .25% overall contract rate so if i send 2000 I am hoping to contract and sell 5 am i crazy?  does it take 6 mailings to see any results?  Thanks in advance for replies
