It's amazing how that works, for that listing, looking into "just listed" postcards to the neighborhood, and when it comes time to "just sold" cards. 

I don't door knock anymore or wholesale on purpose, but I do mail pre-foreclosures and vacant, high-grass houses.To get a letter or postcard from me, the pre-foreclosure must have equity.  

Do you prefer postcards/letters? 

They were pretty reasonable compared to Post Card Mania which is an awesome company but found the same product for cheaper and locally.

I personally dont like YL for the reasons you mentioned, but pretty much all marketing methods work with enough volume (postcards, YL, flares, smoke signals, etc).It DOES attract sellers, since I know some great investors who ONLY use yellow letters.  

Aside from the signs, how else are you planning on marketing, postcards, yellow letters?

Aside from that, you could mail them a yellow post card or letter and see if they are interested in selling.

Sending out large postcards  usually work best with hand writing.I just turned 60 years old and I have plenty to say and I have been learning on BP for about a year full time while I medically recover and this is.

We have tried Jumbo Post cards, Minis, and the handwritten letters.

You could also send postcards, zip letters, or computer generated font letters.
