Direct mailing tax delinquent properties

[Jordan Dahl]

I have a list of tax delinquent properties that I will be direct mailing in the near future and am torn between sending a very straight forward yellow letter or sending something with more information.  It is my understanding that a basic yellow letter stating that I am interested in buying the house gets a higher rate of return on responses but often times is lower quality lead where as a mailer that has more information regarding exactly what we do for people in distressed situations might get less responses but will be a higher quality lead since they know what we have to offer and that we have a general understanding of their situation and still respond anyway. 

Can anyone share their experience mailing tax delinquent properties and what they found works best?  Any advice would be fantastic.  BIGGER POCKETS BABY!
