Dev Horn - see if you can work this into some copy for a postcard for direct mail to absentee owners:
"Friends teasing you about being a slum lord?"
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! Great info on the websites and Mr. Kennedy has a ton of books on Amazon (fortunately at a discount for the kindle editions). I'll be spending lots of time on the deck reading this weekend.
Sharon Vornholt - I started reading your blog after your BP podcast. I was already headed towards direct mail before your podcast, but your endorsement of it made it a certainty. My meager $1500/month marketing budget shifted from bandit signs & sign rentals (with a little direct mail here and there) to direct mail with some bandit signs thrown in every once in awhile. Headed over to your blog right now to see if I can find a link to that book.
Thanks everyone for the great info so far!
