[Michael Dunn]

them, is via a Phone Call ?

I have my Cover Letter and Envelopes ready to go ( with a Picture of the Property copied on the Envelope, bu I am trying to think ahead, and have a plan of action ( well mainly what to say, / How to present myself that I am Interested in purchasing their vacant looking property , etc.  )  If I end up having to Call them to find out if they want to sell. 

Can anyone shed some light please on how to approach the Owners of Vacant/ Distressed looking properties, when we are Driving For Dollars and wish to purchase the property from them ?

Thanks so much
