Look for people who have specific catalysts and are pulling their hair out, preferably in big clumps.Don't show up with hair spray and brushes.

I'm new to direct mail but I do think that a >10% response even with a yellow letter to a good list is better than you should expect.For the postcards that seems just a hair low.I think for that many pieces I would have expected 10+/-3 calls so not that far off.

The other thing I would do is make sure you tell everyone you know or encounter that you're looking to buy, (family, friends, hair salon, nail salon, literally anyone you can engage in small talk).

It's great for pizza and hair salons however not selling a specific piece of real estate.I would however send a postcard to the following list of property owners.

@Wayne Brooks My Rays are prescription and I can't grow hair anymore except places it shouldn't grow.

@Shane Woods If wanting to do EDDM I would suggest going in with other business owners to help cover the cost as the cost per preferred prospect is much higher to you when using EDDM.Pick a hair, nail, pizza, and  restaurant to share the cost with and have them split the cost equally thus making your ad space free besides the time investment. 

The housing authority has the landlord by the short hairs.

Yeah, the math works but it seems like splitting hairs to me.

The previous tenant was a guy , he didnt bake , had work uniforms( little laundry)  , didnt keep the place 80 degrees , and was bald , no hair to dry .  

Like 5-10 minutes.Sometimes I hate my age, height, hair color, and gender.
