Wholesale Mailing Question

[Reuben Royal]

So I'm just starting out attempting wholesaling and I'm going to attempt mailers to a variety of property owners and I have a couple questions. First up, I intend to mail to substitute trustees and people who are nearing or in pre foreclosure. With these types of people, what type of wording should I use on my postcards? What kind of post card design works best? 

Second question, I also intend to mail to a variety of high equity owners as well, and curious as to the best wording to use for these also.

Thanks in advance for any help
