has anyone used black book data or some similar service that tracks home owners who are late on their payments?

I have seen people coming out with a black eye. 

In my (our) area it can be a challenge to find a house without "black fuzzy staining" somewhere.  

Set a criteria at your screening agency and set up a pass or fail criteria...its not grey its black and white fail or pass.

@Aksel A. glad you made it last night to Black Diamond, hope you enjoyed it. 

It's black and white not grey.

Big yellow print - black background - 5.5 x 8.5 postcards with a "you might be a landlord if..." style list on the back of the card.I prefer humor and/or shock for attention getters.Chris Cho & Arthur Garcia - thanks!

The XL black cartridge costs 36 bucks and does about 2,500 full size pages.

I've been using the very basic 4.25 x 6 yellow postcards (with plain, black ink) for almost all of my mailings for the past five years, and I don't think I've ever gotten a response rate of less than 5% (at least, none that I can remember).
