How long do YOU wait to offer cash for keys?

[Tomas Calvino]

Hello,

Do you believe in cash for keys? If you do and have done it before. 

How long do you wait to offer them the cash? I'm guessing you'll serve notice first, but do you get the legal work started to try to scare them into paying? I'm guessing if you want to avoid an eviction you'll offer the cash before you start paying a lawyer. 

I know everyone has had different situations. So how was yours? 

I'm interested in reading how that went.
