What are the "best" motivated sellers to target?

[Brett Allender]

Obviously this is purely an opinion with no right or wrong answers, but just want to hear from wholesalers (with at least some success) share which type of motivated sellers they have had the most success. 

I am trying to determine which group to target with yellow letters...absentee, probate, high equity, landlords, pre-foreclosure, etc. 

All opinions greatly appreciated!
