Paying for moving costs of a free market tenant

[Daniel Greenblatt]

I am purchasing a property where there is a tenant with no lease that I want to get out.  The difference between what he is paying in rent and market rent is approximately $3k per month.

As many of you know, to start a holdover case is going to take a minimum of four months to get him out and could take as long as a year if the tenant knows how to play the game.

I offered to help him out with moving costs but the amount he came up with is way too high. 

What is a fair price to pay him?
