Sending direct mail to homes in default?

[Tyler McLeod]

So i have been browsing BP and learning from all the great content! I have spent some time browsing the County Deed Records looking for Notices. I also have been looking at sites such as zillow for pre foreclosures. Would you recommend sending a direct letter to homes that are already in default? I am trying to narrow down and master my strategies for finding the best deals in my area! 

Thanks for all the help!
