Cash for keys is definitely the best way to get people out in the day when I was very active at court houses steps cash for keys was by far the best way to get folks to move and bad tenants in a state with bad eviction laws to me would be the preferred method. you simply pay them when they are leaving the house not before.. that works fine and you give them more than 1k .. you make it worth their while..

This is the simplest method, but it also means your tenants are more likely to abuse the utilities by leaving windows open with the heat or A/C running, leaving lights on, ignoring the toilet that constantly flushes on its own, etc.3.

And while nothing is foolproof the most consistent method of finding good vendors is relying on OTHER real estate investors that have worked with those vendors. 

What's the highest success percentage method to find a previous tenant's new address for this? 

My experience with friends/some clients is get their numbers via whatever method you can and reach out via the phone.
