I'm using yellow paper and printing lines on it from a template.  

After reading I've decided to go with yellow postcard and it was a huge success. 

And that turned out to be a company who was selling on behalf of their clients.Following that I sent out 150 Yellow Letters to a Tax Delinquent list - using yellowletters.com - complete with my NZ address and a "local" Florida phone number at the bottom of the letter, and got an amazing response of around 12%.I'm convinced it's the quality of the list which matters, and not (for the most part) locations, so long as it doesn't cost the recipient an arm and a leg to make contact with you.

All the same yellow letter, we buy houses, etc, etc stuff.At this point it is just about impossible to find a good deal on the MLS, and the competition for REOs of any kind is through the roof with multiple offers on every property driving up the price well over asking.

I would like to send out post cards instead of yellow letters.

When finding out about a foreclosure is it inappropriate to knock on their door and talk to them instead of a yellow letter or calling them?

We use the 3 x 5 size and do it in neon colors, instead of just the old fashioned yellow sticky note.

Im going to the courthouse today to get some leads and will be sending out yellow letters soon!

(i.e. what if I spend money on yellow letters, which aren't exactly cheap and don't find any motivated sellers. or even if I do find motivated sellers, how would I know how much to offer so I can make a profit?

Last December/January I did a compressed yellow letter campaign to a single zip code in Austin.
