A lot of sites offer mail lists based on location, the one I use is realtor postcard, and they tend to be cheaper then a specialty list.

Your third time you could do a postcard.

Anyone know of a good site online for creating double sided post cards for cheap??

Personally, if you have the budget, I recommend direct mail at 2,500 or more addresses in a 3 to 5 mailing campaign over 3 to 6 months.3) Postcards are cheaper than letters.

Who do you think I should be targeting, and does putting that I want the home for myself in the letter or postcard make a difference?

We send two pieces of mailers, Yellow Letters & Post Cards.

You can do postcards for about 60 cents (total); the "yellow letters" cost about DOUBLE that, so I'm not a huge fan of letters.

I am actually doing post cards and keeping it very simple.
