What does a letter to a possible seller need to say?

[Gary Dale McKee]

Since I am new to the business and have had some trouble finding properties, I am going to start sending letters to owners of properties that look in distress. 

• what does the letter need to say.  

• how does it need to look; does it need to have a picture of me, or can it just be in standard letter format. 

• is there any legal concerns that needs to be addressed.
